Commander Kalfas of Tagrea was afraid of his planet's past. When SG-1 arrived with the crew of the Prometheus, he was cautious and distrusting. In his attempt to protect his people from the dangers he felt Earth's people represented, he relied heavily on his weapons and the use of force. Finally, he was commanded to lay down his weapons and was placed into custody for his attempt to overthrow Chairman Ashwan, in the episode, 6.20 "Memento".
