Elysium is a hospital that specializes in both physical and psychological treatment for former GUILT victims. Elysium is first introduced to us in Under the Knife 2. Heather Ross works at Elysium as a nurse and as Emilio Juarez's personal nurse and caretaker.

Elysium is also the scene of a GUILT outbreak, where a mutated version of Kyriaki reappears after three years.
