Faithmarked

A faction in Skull City. This order of necromancers and their undead servants worship Acererak zealously. They believe that the demilich is alive, but that his abandoning the tomb shows his wrath against unknown transgressions on their part. The Faithmarked seek their deity’s favor and pardon, primarily by destroying the “heathen” Blackfire Disciples wherever they find them.
The Faithmarked bear the image of a skull on their foreheads, weapons, and armor.
