Although there is very little known about his past, it was believed that Lord Tantalus was an experiment of the rouge Dreaming Celestial
. It is documented that he inspired the members of the original Deviant races to raise a "Holy War" against the baseline creatures of their homeworlds. His crusade eventually brought him to Tebel, where he was shocked to meet Nirvana, daughter of Khult, a Deviant woman who was immune to his Black Legacy. Tantalus made her his wife, and renamed his homeworld from Arqa to Armechadon.
