Rolan was a planet in Lucian Alliance territory. A caravan of kassa being towed by an al'kesh was attacked by SG-1 in the region of space near Rolan. The kassa crop was destroyed, but the members of SG-1 who bordered the vessel (everyone but Vala who was flying the cloaked tel'tak) were tagged with an isotope, making them trackable to bounty hunters wanting to receive the Lucian Alliance's reward for capturing the team.
Unknown if Stargate is on planet
