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.
