So the Bosmer and Khajiit worship Baan-Dar as the god of thieves and trickery and cunning. Yet Nocturnal seems to be the God of Thieves for the Thieves Guild, at least in Oblivion and Skyrim.

For reference, here are the wiki entries on the two: http://www.uesp.net/wiki/Lore:Baan_Dar

http://www.uesp.net/wiki/Lore:Nocturnal

Is there any connection between the two divinities? And what would that connection be? Are they different faces of the same god? Does one come from or depend on the other? Or is there no relation at all?

It seems there should be some connection, since Bosmer and Khajiit are such great thieves, and seem to be a natural fit for Thieves Guild characters in game. But how would Bosmer and Khajiit reconcile their traditional connection with Baan-Dar, with the T.G. connection to Nocturnal?
