User blog comment:Lecromis/Sithis: At least a god? The true God of Life and Death?/@comment-3492791-20120822235011

If i'm not mistaken, Sithis is not truly a "being". He is the void. All of it. Thus he transcends what is known to be a god. Primairaly the Aedra and the Daedra.

Since, as mentioned, Sithis doesn't really even care about Nirn, there is no reason for people to what to worship him because he doesn't actually DO anything. Also he is closely assosiated with the Dark Brotherhood. Which i'm sure gives him sort of a bad connotation.
