lorkhan is considered aedric, because he gave most of his power to creat nirn, which, in turn, created Mundus, and Talos is one of the Nine Devines, all of whom are Aedric, and being an Aedra means he fights sithis to remain in control of himself, thus he fights himself, for Talos(an Aedra) and Sithis(Creater and Destroyer) are one and seperate, enemies and family.
