Timeline of the Ancients: Legacy Period: A.D. 2002 to A.D. 2005

Timeline of the Ancients

Introduction

This timeline is part of a larger timeline that covers the over 50-million-year history of the Ancients. To view the entire timeline, visit Timeline of the Ancients, which also includes an overview of the Ancients' evolutionary path and author's notes.

**MAJOR HISTORICAL PERIODS OF THE ANCIENTS**
Date Range	Period	Human	Ascended	Galaxy	Notes
Over 50 million years ago	Alteran	Yes	Uncertain	Original home galaxy, often referred to as simply the Ori galaxy because only the Ori remained there.	The Altera and their brethren the Ori were humans on the evolutionary path toward ascension, but it is unknown if there were ascended beings who existed before or during this period, and if they existed, whether or not the humans were aware of them. The Ori greatly outnumbered the Altera and were preparing to wipe them out because of their conflicting philosophical views. By the end of this period, the only Ancients that existed were the Altera, the mountaintop villagers who chose to leave their home aboard a single spaceship rather than engage in a war. The Ori were left behind to continue on their own path.
5 to 10 million years ago to 50 million years ago	Ancient	Yes	Possible	Primarily in the Milky Way, their new home that they named "Avalon". The Altera became known as the Ancients.	This period includes the establishment of the Stargate network in the Milky Way, the exploration of their new home galaxy and others through the launch of their exploration fleet of Stargate-seeding starships and follow-up exploration vessel Destiny (see Stargate Universe), the formation of alliances, the advancement in weapons and other technology, the development of the means to collect and store their accumulated knowledge, and the continued research into the acceleration of evolution through genetic alteration to achieve ascension. Some of the Ancients had evolved to the point that they could ascend on their own. The defining moment that ends this period is the occurrence of the plague that swept throughout the galaxy that forced the Ancients to ascend, to leave the galaxy, or to die out. Because of the plague and the heightened research into ascension, the Ancients never boarded Destiny, but instead left the exploration fleet to continue on its automated course.
10,000 years ago to 5 to 10 million years ago	Lantian	Yes	Yes	Pegasus. The Ancients were called the Ancestors by the humans of the Pegasus galaxy.	This period opens with the plague sweeping throughout the Milky Way that forced the Ancients to leave the galaxy in one form or another—whether it be by ascending, by leaving the galaxy as humans (in spaceships, for example), or by dying out. The Ancients that ascended joined together in a collective called The Others. The Ori, although not hit by a plague, also ascended and established themselves as the gods of the religion "Origin". This period also includes the creation of the second generation (evolution) of humanity in the three galaxies: the original Altera/Ori home galaxy, the Milky Way, and Pegasus. As they did in the Milky Way, the Ancients in Pegasus built a Stargate network and settled on several planets. By the end of this period, more Ancients had ascended and apparently joined their own ancestors who were with The Others; however, no more ascended beings joined the Ori because the Ori did not wish to share their power and prevented their humanity from evolving to the point where they could ascend on their own or through the use of advanced technology. This period ends when the last of the Lantian survivors of the Wraith-Ancient War abandoned Atlantis and used the Stargate to return to Earth, where they blended into Earth's societies, left the planet through the Stargate, or ascended.
Present to 10,000 years ago	Legacy	Possible	Yes	All except original home galaxy.	This is when the majority of Ancients are Ascended Beings, and other races use and abuse their legacy. At the beginning of this period, the Lantian Ancients had just returned to Earth after abandoning Pegasus to the Wraith and chose to blend in with Earth's societies, to leave Earth through the Stargate, or to ascend. Proof of the Ancients' blending into the human population of the Milky Way is the natural occurrence of the ATA gene (Ancient Technology Activation gene) that allows the possessor to activate and interface with genetically-keyed Ancient technology, as well as the cultural influences of the world's ancient civilizations. Some Ancients from earlier in this period survived into the modern era in human form via stasis, time travel, or some other form of technological means, while a few Ascended Ancients chose to retake human form. This period includes the reopening of the Stargate in modern times and a near-repeat of history as the humans of Earth assimilate the Ancients' legacy, which not only includes knowledge and technology, but also old rivalries that the Ancients had failed to resolve. It also includes the discovery of Destiny, which opened up the universe to exploration (albeit limited) and to the exposure to new life forms untouched by Ancient hands.

ca A.D. 2002-2003

This time estimate corresponds to Season Six of Stargate SG-1.

Ancient woman is discovered in Antarctica; Daniel Jackson interferes while ascended; Anubis destroys Abydos; Oma ascends the Abydonians; The search begins for the Lost City of the Ancients:

True to his Goa'uld nature, Anubis used left over Ancient technology to further his position among the System Lords. He had promised that he'd deal a serious blow to the Tok'ra and Tau'ri. Anubis found an Ancient-built Stargate Destroyer (for lack of a better term) that caused an energy build-up in a target Stargate's capaciters that would result in a massive explosion. Such an explosion, enhanced by the naquadah in the Stargate's composition, would wipe out life on the planet. Unfortunately, Stargate Command had no way of stopping the explosion, so they removed the Stargate from Earth, and it exploded a safe distance away. This was the end of the Antarctic Stargate. The Russians leased the Giza Stargate to the Air Force so that the Stargate Program could continue. Teal'c's son Rya'c destroyed the Ancient weapon. (6.01 "Redemption Part 1", 6.02 "Redemption Part 2")
An Ancient woman was discovered in the ice in Antarctica, not too far from where the Stargate had been found several years prior. She miraculously revived when the ice around her began to thaw. Some of her brain functions were impaired, but she managed to learn how to speak some English and to communicate with the research team and SG-1. Ayiana, as she was named by the researchers, demonstrated advanced human abilities, especially that of healing through touch. Her genetic make-up was similar to modern man's, but there were notable differences. Ayiana carried the plague that killed many of the Ancients, and she exposed the members of the team to it. She was able to heal all of them except for Jack O'Neill before she died. (6.04 "Frozen")
The discovery of Ayiana led to the conclusion that modern humans were not the first evolutionary form of humans in the galaxy and that the Ancients lived on Earth millions of years ago. (6.04 "Frozen"; Stargate Atlantis: 1.01 "Rising Part 1")
Because Jack O'Neill had not been cured of the plague at the time of Ayiana's death, he approved to have a Tok'ra symbiote implanted to heal him. The arrangement was just for the time needed to heal O'Neill and to obtain the latest intelligence that the Tok'ra Kanan had gathered on his last mission. Once blended, however, Kanan usurped O'Neill's body to rescue his lover who was a slave to the System Lord Ba'al. When captured, Kanan fled from O'Neill's body, and Ba'al tortured, killed, and revived Jack in the sarcophagus repeatedly for information. While Jack was at his lowest, Daniel visited him to comfort him and to offer ascension, but Jack refused. Because of this, Daniel sought other ways to help and finally interfered by giving mental hints to the rest of SG-1 as to where Jack was and how to give him a fighting chance. The work Daniel did in secret helped O'Neill and the female slave escape. (6.06 "Abyss")
SG-1 discovered Egeria, Ra's rival and queen of the Tok'ra, on the planet Pangar. Egeria died soon thereafter, but not before helping the Pangarans resolve their Tretonin addiction. The Tok'ra reverently mourned Egeria and then commenced the reformulation of the drug to save Jaffa. (6.10 "Cure")
Earth built its first starship, called Prometheus, which was the product of combining their own technologies with those of the Goa'uld, Asgard, and Ancients. (6.11 "Prometheus")
The Asgard managed to use the remains of the android Reese to call all of the Replicators in the known universe to assemble on the planet Hala in another galaxy. They then activated a time dilation field around the planet so that time progressed much more slowly within the field, giving the Asgard the time they needed to figure out a solution to their "bug" problem. Unfortunately, the Replicators had assimilated some very advanced technology (most likely from a distant galaxy) that enabled them to figure out how to reverse the time dilation so that time inside the bubble moved faster relative to that outside. The Replicators evolved into human form, taking on the image of their creator, Reese. SG-1 managed to reactivate the dilation field, but one of the Replicators named "Fifth" was very close to the device, which meant that there wasn't very much time for the Asgard to find another solution. (5.01 "Enemies Part 2", 6.12 "Unnatural Selection")
SG-1 discovered a planet formerly belonging to the Furlings, the fourth in the Alliance of the Four Races, but there were no living beings left there. There was a transporter system that took travelers to the planet's moon, but all other Furling evidence was long removed. All that was left on the moon when SG-1 arrived were the skeletons that appeared to be those of humans and of a Goa'uld, who had infiltrated this "utopia", where only the "righteous" and unarmed could pass. The Goa'uld introduced a halluciogenic plant to the colony that caused the people to kill him and each other. Not much else is known about the Furlings, who seemed to have simply vanished. (6.15 "Paradise Lost")
SG-1 found that the Goa'uld Nirrti was using an Ancient DNA Manipulation Device to engineer an advanced human host, or hok'taur, on a group of humans on P3X-367. Nirrti apparently didn't have the same background in the Ancients' research on ascension as Anubis had, so her experiments were done in a hit-and-miss fashion, resulting in gross mutations and death. Some of the subjects did display the advanced human characteristics that Ancients had, such as telekinesis, enhanced strength, and the ability to read others' minds. Some of the alterations Nirrti did to team member Jonas Quinn resulted in his ability to see future events, but Jonas lost the ability when a near-fatal brain tumor was removed. Nirrti's subjects on P3X-367 killed her and then destroyed the Device after they returned themselves to their original states. (6.16 "Metamorphosis, 6.21 "Prophecy")
Master Bra'tac and Teal'c were gathered at a summit for Rebel Jaffa on Kresh'tar when they and over 100 other Jaffa were attacked. The assailants removed the symbiotes from all of the Jaffa's pouches, except for one. Teal'c and Bra'tac shared the symbiote until help arrived. For three days, the two were very close to death. Daniel visited them and interacted with Teal'c in his "dreams" to keep him encouraged to save himself and Bra'tac. The two Jaffa survived and were given the reformulation of Tretonin that the Tok'ra had successfully engineered specifically for the Jaffa to end their dependence on Goa'uld symbiotes. (6.19 "Changeling")
Daniel's adopted home Abydos was in trouble, and he couldn't stand by and do nothing, so he contacted Jack O'Neill to ask him to help the Abydonians fight off Anubis, who was going there in search of the Eye of Ra, a device that Anubis needed to enhance a powerful weapon for his new mothership. Anubis had already collected the other Eyes, including the Eye of Tiamat that had been buried in the rubble of the ziggurat on P2X-338, and he only needed the Eye of Ra to complete the set of six. SG-1 thought that maybe they could find the Eye before Anubis, so Daniel began helping them look for it. He found the tablet written in one of the oldest forms of Ancient that Ra had stored away that told of a "lost city" where powerful weapons were located (the name "Atlantis" was not written on the tablet). This tablet was quite valuable, since whoever found the "lost city" would surely have galactic domination. Daniel said that he didn't know about the "lost city" identified in the tablet, but he promised he'd help them look for it. The team had by this time found the Eye of Ra, and they used it as a bargaining chip to get off of the planet with the tablet. The team left thinking that Daniel would protect the Abydonians. (5.08 "The Tomb", 6.22 "Full Circle")
To buy time for his friends' escape and to protect his people, Daniel confronted Anubis, whom he learned was a "bastardized" version of an ascended being, but Oma Desala pulled Daniel out of the confrontation before he could destroy Anubis. With Daniel's interference gone, Anubis used the weapon on Abydos, and all of the Abydonians were killed, but Oma helped all of them to ascend. Afterwards, SG-1 returned to Abydos through a Stargate temporarily created by the ascended Abydonians, and found that Daniel's whereabouts were unknown to Skaara, who was now an ascended being himself. Skaara bid O'Neill a fond farewell and kept the Stargate on the planet long enough for the team to return to Earth. At that point, the team concluded that something terrible had happened to Daniel because he had failed to stop Anubis. (6.22 "Full Circle")

ca A.D. 2003-2004

This time estimate corresponds to Season Seven of Stargate SG-1.

Daniel Jackson returns to human form and becomes a target for his ascended knowledge; Sekhmet is used in genetic research; The search for the Lost City continues:

Daniel's ascension ended when he made the choice to return to human form after he discovered that Oma had ascended Anubis and then removed him from his confrontation with Anubis on Abydos for fear that The Others would do something worse to him. Daniel was angry that The Others permitted Anubis to continue wreaking havoc as the powerful ascended beings stood by and did nothing to stop him. Their punishment for Oma's breaking of the non-interference rules and ascending Anubis was to make her watch powerlessly as Anubis continued his evil plans. Daniel, speaking from the heart, argued that it was wrong, but The Others paid no heed, and when he made his decision to return to human form, the rules of The Others dictated that Oma remove all of Daniel's memories, but she broke the rules once again and merely buried his memories deep into his subconscious mind. She made the ascended knowledge inaccessible for Daniel's own protection, but apparently felt that he deserved to keep it. She sent him in this amnesic state totally naked and alone to Vis Uban, where he was discovered and taken in by the nomads who occupied the Ancient ruins there. Daniel didn't even know who he was, so the nomads gave him the name "Arrom", which means "naked one". (7.01 "Fallen Part 1", 8.18 "Threads", 10.03 "The Pegasus Project", 10.11 "The Quest Part 2")
While Jonas Quinn, Daniel's replacement on the SG-1 team, was translating the Abydos tablet, he was hit with a sudden bit of inspiration and determined that the "lost city" was really the "city of the lost" and that it was the last planet that the Ancients listed in the Repository of Knowledge from the "Place of Our Legacy" that O'Neill had accessed. The team went to this planet, Vis Uban, found Daniel there, and convinced him to return to Earth with them so that he could learn about himself. Jonas's translation of "city of the lost" was wrong, but most likely a hint provided to him by Oma so that Daniel could be found and returned home. (7.01 "Fallen Part 1")
On the first night of his being back at Stargate Command, Daniel started to remember key parts of his past: specifically, Sha're's name and what the Abydos tablet said. He corrected Jonas's translation and told the team that the "lost city" was "still lost", his assumption being that it was purposefully hidden by the Ancients under some kind of camouflage. Amazingly, this was an accurate description of what had happened to Atlantis 10,000 years ago in the Pegasus Galaxy: they had submerged the city into the ocean to protect and hide it from the Wraith. Their strategy apparently worked, since the city still sat untouched by the Wraith at the bottom of the ocean all of those thousands of years. (7.01 "Fallen Part 1"; Stargate Atlantis: 1.01 "Rising Part 1", 3.20 "First Strike Part 1")
SG-1 used Anubis's pursuit of Ancient knowledge against him and led him into a trap on Vis Uban where they destroyed the superweapon on his mothership and sent the System Lords against him to battle it out. Unfortunately, Jonas was captured during the mission, and his mind was probed. This probe gave Anubis all the information he needed to begin his own search for the "lost city". (7.01 "Fallen Part 1", 7.02 "Homecoming Part 2")
The majority of Daniel's pre-ascension memories returned to him soon thereafter, but he still was unsure why he had returned to human form. He felt great uneasiness not knowing if the decision to return was his or if he was thrown out. As he continued to try to remember his time ascended through meditation, he recalled seeing Bra'tac and Rya'c being taken prisoner on Ba'al's planet Erebus, and with that knowledge, he helped to rescue them and the other slaves in the camp. Even though Daniel couldn't remember all the details surrounding his return to human form, he finally made peace with himself and determined that he belonged on Earth as a human striving to help humanity any way he could, rather than as an ascended who was pursuing his own enlightenment at the cost of the sacrifices made by so many others while he did nothing but watch. (7.04 "Orpheus", 8.18 "Threads")
Anubis began creating his cloned Kull Warrior army using the technology of the Telchak Device and sarcophagus. These warriors were implanted with symbiotes with limited intelligence that made them strong and completely loyal. Anubis started to send these warriors out to eliminate lesser Goa'uld and absorb their domains. The warriors' creation was probably a reaction to the Jaffa Rebellion, but Anubis soon realized that the Tok'ra and Tau'ri had developed technology that could kill them easily, so it is possible that he soon began experimenting with creating a new type of warrior, a type of harsesis who had his own "genetic" memories, who could join him in the ascended planes after eight treatments with an Ancient DNA Manipulation Device gave them the physiology of the Ancients in their advanced human form. (7.11 "Evolution Part 1", 7.12 "Evolution Part 2", 7.16 "Death Knell", 9.09 "Prototype")
Daniel wasn't given the chance to adjust to his new life for very long before his ascended knowledge became the target of Anubis, who apparently knew that Daniel's memories of his time ascended were buried in his subconscious mind. Anubis sent his lieutenant Osiris (hosted by Daniel's former lover Sarah Gardner) to probe Daniel's mind while he slept. Osiris was captured and the symbiote removed (and most likely killed in the process). Finally, Daniel was able to save someone he loved from the Goa'uld (he had a very hard time forgiving himself for reopening the Stargate on Abydos that resulted in Sha're's being taken as a host and eventually killed while still a prisoner in her own body). (4.14 "The Curse", 5.21 "Meridian", 7.15 "Chimera", 10.07 "Counterstrike")
The canopic jar containing the banished Goa'uld symbiote Sekhmet was obtained by a rogue cell of the NID and the symbiote was used in unethical research to create a human-Goa'uld hybrid who could access the Goa'uld's vast genetic memory. The jar had been found by Napoleon in Egypt and eventually made it into the hands of the Nazis and then the son of a Nazi war criminal, Dr. Keffler. The hybrid, named Anna, was used by Keffler to commit mass murder (over 30 people were killed in the research facility) and to threaten Orange County, California, with a naquadah bomb. Even though SG-1 tried to help Anna, she couldn't be saved. More than likely, the Goa'uld symbiote Sekhmet also died (whether or not the symbiote was alive upon discovery was not revealed, but her being alive was not a requirement since merely her DNA was harvested for the research). (7.19 "Resurrection")
Anubis and Stargate Command were in a race to find the location of the "Lost City of the Ancients". The race came very close on the planet P3X-439, where Jack O'Neill took a second download from a Repository of Knowledge. After the download, SG-1 destroyed the Repository so that Anubis couldn't access it. Jack led his team to Praclarush Taonas, where he showed the location of the Lost City of the Ancients: it was Atlantis on Earth in Antarctica from 30 million years ago! While at the Taonas Outpost, the team picked up a rare power source, later called a Zero Point Module (ZPM), that permitted Jack to power up the defense weapons in the Antarctic Outpost that destroyed Anubis's massive fleet in the skies of Antarctica and in Earth's orbit. Until Jack could access the Ancient defense weapons, the Prometheus under the command of Gen. George Hammond and a squadron of F-302 intercept fighters led by Lt. Col. Cameron Mitchell battled Anubis's death gliders and al'kesh over the skies of Antarctica. (7.21 "Lost City Part 1", 7.22 "Lost City Part 2", 9.01 "Avalon Part 1")
Jack, unfortunately, was about to die from the download, so he instructed that he be placed in a stasis chamber that was located in the Outpost. The Asgard had saved him from the first download, so his team knew to look for Thor to help this time as well. Several of the F-302 pilots were killed, but Mitchell survived, and he faced at least a year's worth of intense physical therapy to return to active duty. (7.21 "Lost City Part 1", 7.22 "Lost City Part 2", 8.01 "New Order Part 1", 9.01 "Avalon Part 1", 9.02 "Avalon Part 2")
The Antarctic Outpost wasn't Atlantis, though, so the search had to continue, but at least Anubis had been eliminated as a threat, or so it was thought. (7.22 "Lost City Part 2")

ca A.D. 2004-2005

This time estimate corresponds to Season Eight of Stargate SG-1 and Season One (and a small portion of Season Two) of Stargate Atlantis.

The Replicators emerge with a new leader; Atlantis is discovered; Atlantis Expedition reawakens the Wraith; Sacrifices are made on two planes of existence as the Goa'uld, Replicators, and Anubis are defeated:

Carter and Teal'c found Thor near where Hala used to be. The Asgard were monitoring the Replicators in their time dilation field and decided that the best course of action would be to destroy the entire planet by blowing up Hala's sun to create a black hole. Thor retrieved Jack from the stasis chamber in Antarctica and asked him to use his advanced knowledge to create a means to defeat the Replicators, who had used the time dilation device to escape the gravitational pull of the black hole and were heading toward the Asgard's new homeworld. Jack accessed Ancient knowledge and developed an anti-replicator weapon that emitted a frequency that severed the bonds holding the nanites together. The weapon worked, but Fifth escaped. (8.01 "New Order Part 1", 8.02 "New Order Part 2")
Fifth captured Carter and tortured her for her betrayal (when she promised that SG-1 was taking him with them when they turned the time dilation field back on against the other human form Replicators). After she begged him for mercy, he tried to persuade her to stay with him because he loved her. She pursuaded him to let her go, and he did, but afterwards, he created a human form Replicator in her image that had her memories. (6.12 "Unnatural Selection", 8.02 "New Order Part 2")
Daniel went to the Antarctic Outpost to conduct research into the destination of Atlantis while an international team of engineers and scientists studied other aspects of the Outpost. Once Daniel discovered that Atlantis had been taken to the Pegasus Galaxy, Dr. Elizabeth Weir assembled a team of "the best and brightest" to go through the Stargate. Even though the trip was dangerous, the team felt that it would be worth the risk if they found living Ancients. O'Neill, who was promoted and given command of the SGC base, allowed the Expedition to go, but forbade Daniel to, claiming he needed him in the Milky Way. (Stargate Atlantis: 1.01 "Rising Part 1")
Upon the Atlantis Expedition's arrival to the Lost City of the Ancients, it became readily apparent that they needed to find new Zero Point Modules (ZPMs), as Dr. Rodney McKay called them, to power the city-ship's shields that were holding back the water in which it was submerged. On their first trip through the Atlantis Stargate, Col. Marshall Sumner and his team, including Maj. John Sheppard and Lt. Aiden Ford, met the Athosians and learned about the long-abandoned City of the Ancestors and about the Wraith, who attacked when Sheppard, a possessor of the Ancient gene, unwittingly touched an amulet that the Wraith had created to detect Ancients. The Wraith took several prisoners, and Sheppard followed on a rescue mission. Just like the Ancients over 10,000 years ago, Sheppard's team awakened the entire lot of the Wraith when Sheppard killed the Wraith's Keeper. Col. Sumner was also killed on this first mission, but Sheppard managed to save most of the Athosians, including Teyla Emmagan, their leader who soon joined his Stargate team. (Stargate Atlantis: 1.01 "Rising Part 1", 1.02 "Rising Part 2", 1.05 "Suspicion")
Anubis had not been destroyed along with his fleet in Earth's orbit. He managed to possess the bodies of one person after another, starting with a Russian cosmonaut who was in the International Space Station, until he got to the Stargate. Whenever he inhabited a person's body, he took over completely, but memories of the possession remained in the host, just like what happens when a Goa'uld takes a human host. Anubis's energy form had a detrimental effect on the host's body, however, similar to radiation poisoning. Daniel proposed that they attempt to get Anubis to break the rules and gain the attention of The Others, but Anubis managed to get the Stargate on his own. Carter programmed the Stargate to a connect to a frozen planet, where Anubis was stuck for a short time. (8.03 "Lockdown", 8.16 "Reckoning Part 1")
Dr. Carson Beckett was a member of the Atlantis Expedition and was the one to isolate the Ancient Technology Activation gene. He also possessed the gene, but it was rare and varied in strength from individual to individual. He created a gene therapy for those who didn't possess the gene naturally, but this therapy had only a 47% success rate. Remarkably, the inoculation takes only an hour to become effective. (Stargate Atlantis: 1.01 "Rising Part 1", 1.03 "Hide and Seek", 3.03 "Irresistible")
The Atlantis Expedition found a lab with an energy lifeform inside a trap that the Lantians were studying for their genetic alteration toward ascension. The lifeform fed off of other forms of energy and the Expedition had to get rid of it by sending it through the Stargate to a barren planet. The existence of ascension research on Atlantis proves that the Ancients tried several artificial ways to reach ascension for those who were not able to do it on their own, indicating that not Ancients evolved to have the ability naturally. The origin of the energy lifeform is not known, so it is possible that it could have been brought to the Pegasus Galaxy when the Lantians left Earth 5-10 million years ago after those that could ascend did so in order to escape the plague. This would indicate that the Ancients who were on Atlantis when it first arrived in the Pegasus Galaxy either chose not to ascend or were unable to ascend on their own and were seeking to intervene in evolution in order to do so. (Stargate Atlantis: 1.03 "Hide and Seek")
A few months after their arrival, Sheppard and McKay began to explore the east pier of Atlantis where they found the "Oracle" room from the Lantians' sociological experiment. Not realizing that the societies were real, the two thought that the control room was a very sophisticated simulation program. They called it a "game", unaware of how their competitive actions were affecting real lives on another planet. (Stargate Atlantis: 3.15 "The Game")
Goa'uld came to Earth and began taking top executives and government officials as hosts, but the existence of alien life and the Stargate network remained outside of public knowledge. At one point, the Goa'uld tried to start a nuclear war just so that they could gain access to the Ancient Outpost in Antarctica, which was the location of the powerful defense weapon that was used against Anubis's fleet, but they were stopped just as the Russians were about the launch the first missile. (8.08 "Covenant", 8.10 "Endgame")
The Replicator duplicate of Carter tricked Carter into helping her gain access to the Asgard's anti-replicator technology and destroyed Fifth with it in orbit over the Alpha Site. She escaped and began her own plan to take over the galaxy, starting with the Goa'uld. (8.11 "Gemini", 8.16 "Reckoning Part 1")
The Atlantis Expedition discovered the Lagrange Point Satellite that was a weapons platform and the last line of defense for Atlantis during the Ancient-Wrath War. On a planet nearby, a lone surviving Wraith that was aboard a cargo ship loaded with humans for food was encountered. He had lived those 10,000 years by hibernating and feeding off of the human cargo and the other Wraith crewmen. He proved how very hard the Wraith are to kill by surviving all kinds of attacks thrown at him, including Wraith grenades and P-90 bullets. It took an Ancient drone fired from a puddle jumper to take him down permanently. (Stargate Atlantis: 1.12 "The Defiant One")
While exploring Atlantis, Expedition scientists found a nanotechnology lab from which some of the nanites had escaped from broken containers. The nanovirus killed those humans who didn't have the Ancient gene. The only way to stop the spread of this nanovirus was to expose them to a large electromagnetic pulse (they used a naquadah reactor as a bomb). The discovery of this nanovirus left a very important question: If Ancients didn't create this virus, who did? (Stargate Atlantis: 1.13 "Hot Zone")
The Atlantis Expedition met Chaya, the Ascended Lantian Ancient who had been banished by The Others to Proculus to be their protector. She explained how she could not take in refugees because of her punishment for interfering when the Wraith attacked the planet thousands of years earlier. After this encounter, it appeared that the Expedition did not return to her planet ever again, apparently satisfied that these humans, at least, were safe from the Wraith. (Stargate Atlantis: 1.14 "Sanctuary")
Because they hadn't heard from the Atlantis Expedition since it went through the Stargate, Lt. Gen. George Hammond, now head of Homeworld Security, assembled a rescue crew on the Prometheus, including Dr. Daniel Jackson. Unfortunately, the ship was damaged and unable to complete the mission because a pirate named Vala Mal Doran hijacked the ship, which was subsequently attacked by Ba'al's forces when its defense shields were down. Vala escaped after the attack, and the Prometheus had to return to Earth for repairs. (8.12 "Prometheus Unbound")
SG-1 discovered an Ancient time machine built inside a puddle jumper on a planet in the Milky Way. The time traveling Ancient (most likely the Atlantian Ancient Janus) recorded what he saw in the future on stone pillars. Daniel read the Ancient text that led to SG-1's search and discovery of the timeship. General Jack O'Neill was called in to fly the timeship since he had the genes needed to interface with Ancient technology. It was taken to Area 51 for study. (8.13 "It's Good to Be King")
The Atlantis Expedition found the time traveling Elizabeth Weir in stasis, but she died soon thereafter. In her version of the timeline, Atlantis's shield failed and the city flooded, killing everyone except Sheppard, Zelenka, and herself, who managed to get into a puddle jumper that just so happened to be a timeship. Sheppard flew the craft, but it crashed when they went back in time 10,000 years during the Wraith's siege on the city. Only Weir survived the crash. The Ancients healed her of her injuries and learned about the Expedition. Acting on her information, Janus reprogrammed the city to rise when the Expedition arrived, but Weir had to stay behind to manually rotate the ZPMs. Weir met Moros, the High Councilor, and he was very adamant that she not travel back to her own time, fearing the harm that could come with time travel. He ordered that Janus destroy the timeship, but Janus secretly took his research with him when he abandoned the city. Janus was the only one who knew Weir remained in the city in stasis, and before he left, he gave her a note with five Stargate addresses where he knew there to be ZPMs. (Stargate Atlantis: 1.15 "Before I Sleep")
The Atlantis Expedition met several new human societies and learned how some had adjusted to life under Wraith control. The Hoffans developed a drug that could make a human immune to the Wraith's feeding, but would also kill 50% of their people. This drug also killed the Wraith attempting to feed on them. The Genii led two types of lives: one above ground as a primitive agrarian society; the other, underground as a military power building atomic weapons. The Expedition also learned that ZPMs were rare in the Pegasus Galaxy just as they were in the Milky Way. Any ZPMs that were found were already being used as protection against the Wraith or were otherwise inaccessible, including those found on M7G-677 and Dagan, two of the locations that the Lantian Ancient Janus had given the time traveling Weir as places where ZPMs could be found. The people of M7G-677 were protected by an EM shield generated by a ZPM that was close to depletion, and a New Quindosim kept the ZPM hidden in the hopes that the Lantians would return to reclaim the sacred artifact known as the Potentia.

Replicator Carter captured Daniel and probed his mind for his ascended knowledge. She extracted Daniel's memories of his confrontation with Anubis over Abydos when he was pulled out by Oma so that she could prove that she had accessed his ascended memories and that he knew how to defeat Anubis. She also discovered the existence of the device on Dakara that the Ancients used to seed the galaxy with new life after the plague. She recognized that the device could be calibrated to destroy her and her brethren, so she sent her fleet to Dakara to destroy it. In the meantime, Anubis had gotten back into power, and Ba'al was working with him as his lieutenant. Anubis told Ba'al of the weapon's existence, and Ba'al told Stargate Command because he wanted to prevent Anubis from wiping out all life in the galaxy. Anubis sent his fleet to Dakara to annihilate the Rebel Jaffa who had taken over the temple there. (8.16 "Reckoning Part 1", 8.17 "Reckoning Part 2")
Replicator Carter opened Daniel's subconscious mind further and started to extract the "knowledge of the Ancients" to disseminate among her bug-like brethren, but Daniel used it to send the command to all of the Replicators to freeze. This period of inactivity gave Carter and Jacob/Selmak time to calibrate the device on Dakara to destroy the Replicators and leave organic lifeforms unharmed. Replicator Carter killed Daniel to break his control. The time that Daniel had managed to hold the Replicators was enough for Jacob/Selmak to activate the weapon, and all of the Replicators were destroyed throughout the galaxy. (8.16 "Reckoning Part 1", 8.17 "Reckoning Part 2")
The Rebel Jaffa tried to capture Ba'al, the last remaining System Lord, but he escaped and fled, leaving his fleet and domain to the new Free Jaffa Nation, who decided to make Dakara their center of government. (8.17 "Reckoning Part 2", 8.18 "Threads")
Jacob Carter and Selmak died soon after the battle over Dakara, but the alliance between the two peoples continued with Samantha Carter continuing to act has Earth's primary representative. (8.18 "Threads", 10.19 "Dominion")
Oma Desala rescued Daniel's spirit at the time of the Replicators' destruction, placed him in an ethereal diner drawn from his childhood memories, and offered him ascension once again. While he contemplated his options (ascension or death), Anubis entered his plane of existence in the form of a friendly businessman named Jim. Jim and Daniel discussed Daniel's first ascension, and after talking to him and to Oma, Daniel discovered the circumstances of his decision to return to human form from his last time ascended. He also rediscovered how Oma's punishment by The Others had allowed Anubis to continue with his plan to kill every living thing in the galaxy. When The Others, taking on the form of humans eating in the diner, appeared to ignore him, Daniel tried to take action against Anubis himself, but discovered that he had no powers. Finally, Daniel, once again angered by The Others' refusal to act against Anubis, used the last weapon he had, his words, and pleaded for Oma's punishment to be over so that Anubis could be stopped. The Others did not respond, but Oma, moved by Daniel's plea, decided that she should be the one to stop Anubis because she was the one responsible for his ascension. She knew that she could not destroy him, so she chose to engage him in an eternal battle that ended any further interference on either's part. The Others were satisfied with this action and stopped some of the things that had been put into motion because of Anubis's interference. They confused his Kull Warriors on Dakara, and the Jaffa easily defeated them. They also stopped the self-destruct that Stargate Command had started to prevent the fatal wave from the device on Dakara from coming through the Stargate. Daniel was returned to human form (a new, third option), but this time, his memories were left intact. (8.18 "Threads")
The Rebel Jaffa established their new center of government for the new Free Jaffa Nation on Dakara and began restoring the old structures left behind by the Ancients. (8.18 "Threads", 9.01 "Avalon Part 1")
A future version of SG-1 used the timeship to travel 5,000 years into the past when Ra was at the height of his power on Earth. They went there to hunt down a ZPM that was depicted in a book that Daniel had inherited from Catherine Langford at her death. They found the ZPM and put it in a First Dynasty tomb that Daniel knew would be discovered a few weeks prior to their decision to travel back in time, thus eliminating the need for their future selves to travel back in time. The time traveling SG-1 were stuck in Ancient Egypt, though, and died there. (8.19 "Moebius Part 1", 8.20 "Moebius Part 2")
Sheppard's team in Pegasus discovered a Wraith reseach lab in which a Wraith had experimented on humans to make them more compatible with Wraith by making the feeding process more efficient. This meant that he altered the DNA of some humans to have Wraith DNA, but the experiments went wrong when these humans were able to tap into the Wraith's psychic network. Instead of destroying his subjects, he placed them back into the general human population, hoping to dilute the DNA to stop the psychic connections, but still keep the rest of his work intact. Some of these people went mad because they could hear the voices of the Wraith's telepathic communications, while others created special bloodlines wherein the ability to sense the Wraith coming helped their people escape the cullings. Teyla's ancestry included those with traces of Wraith DNA, and her father called it "the gift". Teyla became the leader of her people because she was always the one to sense the Wraith first, even though there were others among her people who also had the ability. (Stargate Atlantis: 1.18 "The Gift")
The discovery of the Wraith scientist's lab revealed that the Wraith language was a derivative of the Ancient language and that their theories that the Ancients were responsible for the creation of the Wraith were true, even if this creation was accidental when humans were placed on the planet where the iratus bug existed. (Stargate Atlantis: 1.18 "The Gift")
The Wraith were on their way to Atlantis with three of their powerful hive ships, but the Expedition managed to destroy one of the hives with the Lagrange Point Satellite before the Wraith destroyed it. The two hive ships continued their approach while the Expedition prepared for the city to be sieged once again. They managed to get a quick message through the Stargate back to Earth, and in response, Gen. O'Neill sent heavily armed Marines commanded by Col. Dillon Everett through the Stargate, using the newly-discovered ZPM from Egypt to power the connection. He then had the ZPM placed on the new BC-304, the Daedalus, to arrive in a record-breaking four days to help to defend the city. It was a close call, but the city was saved by faking a self-destruct.
