The Lich Sheazac

Sheazac began his life as a halfling named Omake on the Westernmost island on the map. As one of the village elders and the sole wizard on the island, he was responsible for being the keeper of arcane knowledge and the authority on all things magical. He grew old and for reasons as of yet unknown, he became unsatisfied with the mortal lifespan. Fearing his impending death he studied Necromancy and discovered and executed the ritual to become a Lich. He did so under the guise of preventing a volcanic eruption on the island but instead sacrificed the souls of his fellow village elders, binding them into a phylactery and then committing suicide. His body stretched and deformed as he assumed the thinly skinned, skeletal form of a Lich, now named Sheazac. He left the island to be destroyed by the volcano

His activities since then have been shrouded in mystery save for the few missions that the Brotherhood has undertaken against the undead. However, it appears that he has built up a stronghold in the southern swamp known as the Breathless Morass and his forces slowly encroach northward.
