lucifer took part in the Great War, fighting alongside humans and his companion, Duke, so that the two races could coexist with one another and live in peace. The Entelexeia lost the war, but Elucifer was greatly injured from it as a result. Humans took advantage of Elucifer's weakened state and killed him out of fear once the war was over, despite his help, which spurred Duke's hatred for humanity. Duke buried him on Ehmead Hill in a grave that looms over the sea, visiting frequently. When Duke fights the protagonists for the final time in Tarqaron, he draws upon Elucifer's strength to assume a new, more powerful combat form.
