Vorgoth

Vorgoth was an ancient wizard, obsessed with necromancy. He established a tower deep in southern Erellion before there were borders and regions. He is known to be the author and creator of spells and items to allow the user to create and control undead. He himself transformed into a lich around year 375.
He was destroyed by the The Circle of the Wise in approximately year 390. Over time adventurers discovered it and attempted to discover it's secrets. Some were more successful than others.
Most recently his tower has become home to Overlord Veth the Forlorn and his minions.
