Bar-Hathor the Flamewalker is one of the otherworldly beings involved in The Great War.
Lore
Bar-Hathor is one among seven beings who is called upon to the realm of men. He could make fire flow like water. During The Great War, a person named Hassatur became a vessel of his manifestation in the realm of men. His vessel was seriously injured twice during the war, though not before bringing down one Qantari legion. He was then taken to the sacred chamber of Mountain Monastery and put into a huge tank that sustained his life. He did not get the chance to be reawakened during the war, however, and remained in the chamber beyond the Titan's Gate, locked for eternity. It appeared that sometime later, the tank failed to sustain his body, and what remained within the tank was eyeballs and some sort of figures that resemble a face.
