My first thought is to play a character who occupies the role of "the weird one" as in something that isn't really a human being/elf but is some other wildcard creature that might elicit some weariness and confusion from others before they realize, "I don't know what the fuck that thing is but it brings x to the table in a really unexpected, out of left field way, so he can stay."

Someone who doesn't have any connection to a god but is along for the ride anyway because they've got something they can offer that you don't really get from the conventional ways. In short, they're the one who just comes out of left field with something you wouldn't expect to need but now you don't want to be without it. Some sort of benevolent (or at least no hostile) monster, maybe an alchemist with shady potions that probably warrant a Geneva convention analogue, a straight up golem, or a ghost possessing a suit of armor, etc.

How do you feel about that? A little weird and wacky companion.
