I'm going to leave the rest alone, as there's really nothing more to the topics than for us to circle around. ;)
I'm pretty sure I read somewhere that Maraad was married to MU Yrel and she died in one of the major battles between the orcs and draenai. In the AU, Maraad was never born, thus which is why she didnt know him in WOD.This gives his sacrifice and the quote "In the light, we are one" a whole new meaning: Marriage being to become one under the light. It was his way of telling her how he felt, and getting closure over the wife he had lost in the MU.
