Muulthim

Muulthim was a monstrous demigod created by Vaeke to slaughter the dwarves of Secera in southern Aduna for their betrayal of their creator. Creating Muulthim used up the last of Vaeke's power, and Muulthim turned the land of Secera into a horrible, deathly landscape until Chaos Legion killed him in an effort to steal away the Divine Spark of Muulthim, which was instead lost to the lich Sullivar.
