Mythic Engine World of Darkness
The Dreamspeaker Spirit Master Lelooska has enslaved the Crooked Beak of Heaven, which is often claimed (by the Wendigo Tribe, who are somewhat acquainted) to be the most fearsome of the foursome. The Beak of Heaven shatters reality where it breathes. Lelooska is the most powerful wizard in the region other than Unagilis.
He appears to be a thrall, just as the other three Dreamspeaker Hamatsa priests.
