- "Doctor Weir, your people have been putting their lives in jeopardy to save my people, and I have rewarded that kindness with doubt and suspicion. I apologize."
- ―Chancellor Lycus[src]
Chancellor Lycus was the leader of the Taranian people. He was present when Lt. Colonel John Sheppard's team arrived on Taranis and told them about the outpost. He later traveled to Atlantis when it was discovered that a super volcano that the outpost derived power from was about to erupt. When the Stargate shut down after he came to Atlantis he accused Dr. Elizabeth Weir of kidnapping him to exchange for the Orion behind the outpost on Taranis, but later found out what had really happened and thanked them for their help. (SGA: "Inferno") He was most likely killed along with the other Taranians by Michael Kenmore. (SGA: "Vengeance")
