Bloodline of Focalor

A cruel taskmaster and sole being responsible for the most horrifying monsters Sheol puts forth, Focalor of the Fiendish Flock is an influential Demon Lord. His creations make up a sizeable portion of the Infernals' armies and his Tieflings are also legion. He never makes the same thing twice, so his Tieflings vary wildly in form and function, but they all share a common trait: a pair of large wings extend from their backs. Many of them additionally bear natural weapons and other mutations that make them more efficient warriors. It does not take a sage to deduce their, and Focalor's, purpose. He is not willing to rest until all bow before the Lords of Sheol.
