The unreliable narrator is ever unreliable. Mortals cannot become Aedra, as Aedra were those eight great et'Ada that gave part of themselves in the creation of Nirn. Arkay is just the Imperial Aspect of the Aedroth that governs Life and Death: the theory that arguably holds the most weight is that his mirror-brothers include the Nordic Orkey, Elven Trinimac, and thus also the Daedric Prince Malacath (who Boethiah transformed Trinimac into).
