So Tall Papa (parallel to Auriel and Magnus/LDK) guides the gods through kalpas to escape Satakal's hunger (parallel to Alduin) and the Yokudan gods are the ones that make it. So Tall Papa creates Sep (parallel to Lorkhan) from the "dead skin" of the previous kalpas to help him when there become too many spirits who persist to keep track of. Sep then creates the mortal realm to which Tall Papa doesn't approve of. Now Sep tries to get people to stop reaching the Far Shores (parallel to Aetherius).
So... how does this fit with what the other races think went down?
