Ilius is a charismatic and pragmatic Forsaken, who leads a branch of the Cult of the Forgotten Shadow. He liked the concept of lightslayers, but disagreed with their implementation. Ilius had been a human scout in life, but before that he had made a living as a sneak thief and burglar. Recalling those skills, he now trains a few faithful cultists and sends them on solitary missions against the Scarlet Crusade. These lightslayers proved much more effective, and their use has spread to many branches of the Forgotten Shadow. They shared more rogue-like qualities, rather than fighting directly.
