Ugrach

Ugrach, Curator of Death, former ruler of the Underworld, where he resided in his fortress of Cor Kanth in the Unsguul Mountains. His creation was sparked from the soulbleed of the multiverse's first death. His son, Slith, now Lord of the Undead in his stead, played a pivotal role in the War of Humanity.

At his immediate beck and call were the five remaining Ur'Vampires - Lieutenants Gerzson, Asztrik, Tizane, Prioska, and Zigana - as well as Death Knight Lord Kemnast, captain of the Death Knights. He kept as his pet a twin-tailed giant scorpion.

When his son slew the god of Death, Thoth, the Divine called a moot trial to decide Slith's fate. Ugrach raced to his son's aid, striking a bargain with the gods by which his son would be punished but not executed, to be locked afterwards in the Underworld, while Ugrach himself abdicated as Lord of the Undead and took over Thoth's role in the guidance of souls within the Halls of Death.

It was his vacancy of the Underworld after eons of rule that sparked The Underworld Rebellion.
