When an army of devils invades to bathe a region in bloodshed and hellfire, it is likely that one of Hell's most powerful and diabolical generals, the pit fiend, masterminded the incursion. Cunning, powerful, and ruthless, pit fiends often serve the archdevils directly. They rule infernal duchies, subjugate mortal worlds, and usurp infernal rivals using unparalleled despotism and calculated ferocity. To realize their tyrannical machinations, pit fiends claim mortal souls that they corrupt into lemure servants, which can then be shaped and transformed through infernal manipulation into the terrifying devils that form Hell's formidable legions. They often select the most wicked and vicious lemures for their armies, drawing upon these lesser devils' depravity during powerful magical ceremonies to create hideous and terrifying abominations that can cow and eviscerate the pit fiend's enemies.
