Ashmodai
So he knows that there are pieces of tech left by Merlin/Moros, and a vault full of gold (which he needs; as he does need money according to the scene in Gringotts) and knowledge of the Sangral, but chooses to leave it alone?
heh would be very interesting if he showed up at stargate command during the Tollan incident :D meeting the Nox and asking them for help or maybe even during one of Asgard visit.. I do hope he helps the Asgard... I do love them but I hate their ending... I know the books gave the Vanir (pegasus Asgards) happy ending but still miss Thor and others...
