Elysium is a Terran Federation colony world.
Elysium was originally one of a series of Pioneer colonies established by the Terran Federation during their Great Expansion. The dedication of the colonists and contact with many species during the Great Expansion led to the establishment of Elysium as a prosperous world.
During the Scoodian War, the Scoodians attacked Elysium in an attempt to intimidate the Terran Federation. However, a woman named Lynda Williams organized the colonists into fighting against the invaders. After the war, the Williams Memorial was erected in the capital of Elysium City.
After the war, Elysium became home to several refugees whose homes were destroyed in the war.
