The Prometheus' resident warforged.
Zellex is a sentient golem who serves as patrolman and muscle aboard the Prometheus. He has a meticulously polished bronze casing, with smooth obsidian inlay, and his eyes are emerald gems that glow brightly when he speaks. Standing seven feet tall and possessing enormous hands and fingers, Zellex is an imposing figure indeed, and is the very definition of a loyal security detail.
He also is, notably, the one member of the current security detail that seems to respond well to Lieutenant Thotuk.
