Vordakai
An ancient and powerful Iobarian Lich warlord. He was a massive skeletal cyclops adorned in robes, ribbons and jewelry. It is believed that he was able to use strange magic by cursing himself. At some point he acquired the Oculus of Abaddon, a powerful artifact which he made into his phylactery and used to summon and subjugate fiends. Due to his hubris and its supposed indestructibly, he carried it visibly on himself as a replacement for his eye. He was killed by The Constellation in 4712 in retaliation for abducting a village, and his phylactery was destroyed by Tristian. The events of his death were popularized by Keraak's retelling and immortalized in a festival complete with a dramatic reenactment.
Predating humanity, Vordakai used to rule over an ancient cyclops civilization in Iobaria and the lands of the Nomen Centaur. His empire fell before Earthfall. For more than a thousand years he operated out of his tomb in The Valley of the Dead.
Vordakai was resistant to cold damage and slightly resistant to physical damage (except for magical bludgeoning). As a wizard, he had a wide range of spells, including Counterspell, Dimension Door, Create Undead, Imprisonment, Paralyze, and Binding Circle. He was also able to attack with his claws, which could stop an enemy's heart temporarily or even permanently. The only known cure for his claw paralytic is panacea.
