The Workings of a Celestial and a Mikaelson

Summary: What if the world of TVDU of the show was a universe that was forcibly taken over by an R, O.B., and made to act out the show when the ROB finished, the world is taken out of alignment with the universe. When God retakes his world, he is stunned as beings he hid his multiverse from have been made aware. Needing a champion to go against his new enemies, God decides to pick Klaus and offers 11 boons. Return to a previous AU world, can the champion fight against evil, or will he fail?
