Vladimirith

The Crooked King and lord of the lost Nyssaor, Vladimirith was birthed by the acidic spittle of Kael'Karum himself. He thirsts to release his master from his prison, but the combined might of the remaining High Conclave keeps him at bay. He was slain by the six Sages atop the Blightspire, and though Kael'Karum was able to elevate him to godhood, the destruction of his physical form placed upon him a curse from the Powers That Be: He can never interfere directly on the Material Plane again.
