Elysium (Earth-5875)

Elysium was a major city on northern Eridanus II, falling under the administration of the Republic of Eridanus II.

History
In 2494, the Insurrectionist group United Liberation Front took control of ridanus II, deposing the Republic of Eridanus II. The UNSC responded to this, driving the insurgents back away. They would try to do again in 2513, now under the command of insurgent leader, Colonel Robert Watts. During Operation TREBUCHET, the whole rebellion was dismantled, and Watts was presumed dead. He, in fact, had faked his own death and hid in the asteroid Eridanus Secundus, starting to lead the remaining of his forces from there.

Elysium was the birthplace of John-117, and also where he grew up before being kidnapped by the Office of Naval Intelligence and replaced with a clone to be used for the SPARTAN-II Program. He grew up alongside Parisa Gusev, and the two became best friends. The two attended the Malala Yousafzai Elementary School, where he was encountered by Dr. Catherine Halsey and Jacob Keyes in 2517.

In 2524, a nightclub favored by CAA personnel after their duty was attacked by Insurrectionist bombers, which killed dozens of civilians, the CAA pilot Allison Stark, and putting Eric Santiago into a coma. Gage Yevgeny and Felicia Sanderson were two of the only survivors.

The city was glassed and destroyed alongside the planet when the Covenant invaded the planet in 2530.
