Lore

Devils personify tyranny, with a totalitarian society dedicated to the domination of mortal life. The shadow of the Nine Hells of Baator extends far across the multiverse, and Asmodeus, the dark lord of Nessus, strives to subjugate the cosmos to satisfy his thirst for power. To do so, he must continually expand his infernal armies, sending his servants to the mortal realm to corrupt the souls from which new devils are spawned.
