Omaka

Omaka was a Warlock of Imix that had acquired hightened arcane powers when he found the ruins of an arcane research facility in the volcanic caves below Bleakburn.

Omaka managed to enslave a powerful Efreet and used his assistance to kill the ruler of the Firenewts and throwing his son (Aytal) in prison, thereby usurping the throne. Despite being under his control and having to protect the warlock, the Efreet was unhappy with this arrangement, tried to spite Omaka however he could and used the group to get out of the Warlock's control.

By causing the volcano to erupt and destroy the city of Bleakburn, the Firenewts managed to capture a majority of villagers that fled the calamity to use as miners in the underground caves.

Omaka, with the help of the Firenewts and slaves, searched the ruins of the arcane research facility for some sort of artifact, which turned out to be a black key, that the group later found in a secret chamber.

Death
Omaka died in the Evergate chamber of the arcane research facility when Integrity incinerated him with holy fire. After the warlock had died, his body was reanimated by a strange necromantic force after which he spoke to group in a different voice and language before being impaled by one of Floyd's crossbow bolts.
