Known only as EK-496 in the lab, Eternal was forcefully retrieved from an advanced research Citadel, brain wiped and re-injected. Then released as a newly augmented capsuleer by an unknown benefactor.
Engineered specifically as a capsuleer from the ground up. EK is naturally blind, but because of his augmentations can still "See" the world around him. Seemingly designed for leadership and combat, Khans plans for new eden are unknown.
