Malgoth

Malgoth is the lord of the Shadowlands, cursed to be forever a prisoner of his own realm. He resents his sisters creations and blames them for his eternal damnation. He does everything in his power to rend the Mortal Realm to ash and would like nothing more for the Shadowlands to swallow up the Mortal Realm.

His worshipers associate him with:
Death, Conquest, Power
