Originally Genie, Asmodeus created Devils in the 3rd age from the most dedicated among the genie, mostly from the Efreet. They willingly used their powers to collectively warp and harden their bodies and souls for combat, burning away all morals and pity and leaving only absolute loyalty to Asmodeus. Their discipline and ruthlessness singlehandedly turned back the Primordials, ending the Prime War. In the 6th age, they followed Asmodeus into Hell, willingly putting themselves on the front lines of an eternal conflict knowing their failure would result in the loss of the entire universe to Narsix.
