Azrakael's Spirit

Azrakael's spirit manifests before you in the Citadel's deepest chamber - the same chamber where you destroyed the Corruptor's avatar. He looks different now: translucent, void-black, his celestial light replaced by void-darkness. "You destroyed my body," he says, his voice like cracking ice. "But the Corruptor gave me a new one - made of nothing. You cannot kill what is already dead, mortal." He attacks. But as you fight, you realize something: his spirit form is weaker than his living form. The Corruptor gave him power, but not enough. He's a shadow of what he was. And shadows can be dispersed.
