My plan for an axis of A-P specialization went something like this:

Choice 1: I like demons.
Choice 2: I like devils.
Choice 3: I like unspeakable Cthulhu-esque alien evil entities. (Or more something like the gods Elric calls upon, if you prefer, but in that rough mold.)
Choice 4: I like mortals and glorify mortal works and magic to a profane degree, roughly treating priests and divine interference as Battle treats magic. I.E. not atheistic because they're damn sure it exists, they just don't like it and what it implies.

Whether that plan would have survived contact with other immortals and/or more detailed planning, who knows!
