Lanudo the Sorrowsworn was a member of the Boneyard's honor guard, protecting the valley of draconic bones from outside influence. When his companions discovered he was selling access to the sacred site he was exiled and branded with one of the worst possible marks - Defiler. He started his exile by collecting a small posse of other exiles, but realized that true vengeance would require supernatural help. Traveling west, he traded the lives of each of his companions in a Mabaran manifest zone for dark powers.
