The ancestral home of the Tevarin species, Elysium was incorporated into the UPE at the end of the First Tevarin War (SEY 2541-2546) and cleared for Human habitation. The system became the focal point of the Second Tevarin War (2603-2610) when the shattered remnants of Warlord Corath'thal's fleet crashed into their former homeworld to end the conflict.
