I think I read somewhere that, in the Spelljammer setting, spelljamming cultures and races have come to the conclusion that all the gods of the different worlds are aspects of the same multiversal pantheon (the Destroyer, the Nurturer...etc.). Do you know any sourcebook were that is explained? Do you know the full list of that multiversal pantheon?.
