I don't follow the idea that Sithis is similar to deadra, or daedra are purely Padomay blood born, but that's just me. I'm more following the concept brought up in Source of Chaos in which it is claimed that Sithis, as a deity, is basically the idea of Padomay as an action mixed with the ideals of Daedra worshipers.

As well as the claims of the Loveletter that Oblivion is the echo of the Void, and that mortal death is the echo of Oblivion, seeming to make it appear that Sithis is Oblivion as it is sort of the middle ground between Void (Padomay in this case) and mortal death (Lorkhan).
