sadly in d&d you can kill the gods. There are stats for them and everything. Of coerce its neigh impossible, but you can. Heck even toee allowed you to kill a god in Cuthbert and Iuz, who's a demi-god (I think?). Oh and the max level was 10, lol!
btw, dwarves rule over the halflings, but that's about it. No big deal as everyone feels sorry for the halflings anyway.
