Re: Shifting realms?
Serving a different deity would be a descending into lower realms for me. "Serving" is not the right term, however. I am "part of" the univeral notion or consciousness of creation that is everything and everywhere in the multiverse. Serving a different entity would mean a kind of idolatry to me. So I am part of the multiverse's consciousness in its purpose.
Of course there are many that serve a personified deity, being a messenger of it and all. However I cannot imagine that one changes that assignment. But: in the same pantheon, where more then only one deity is hanging around I can think of such incidence. But I am quite sure that this remains an exception.
