Fedallah was a powerful psychic that was killed by a massive white whale known as Moby Dick. He became a powerful spirit, and trained Amelia Astelle. He resided in limbo, living in a small hut where he kept various knick-knacks. Amelia eventually killed him, and stole a holy amulet from his house, the amulet that contained a powerful wraith.
Fedallah was gifted with the powers of prediction. As a spirit, he could fly, teleport short distances, cross dimensions, and, as all demons, could become a vicious beast with sharp claws and glowing red eyes.
