There are such things as dwarf gods. Dwarfs are not a naturally relgious species, but in a world where pit props could crack without warning and pockets of
fire damp could suddelny explode they'd seen the need for gods as the sort of supernatural equivalent of a hard hat. Besides, when you hit your thumb with
an eight pound hammer it's nice to be able to blaspheme. It takes a very special and strong minded kind of aetheist to jump up and down with their hand
clasped under their armpit and scream "Oh, random-fluctuations-in-the-space-time-continuum," or "Aaargh, primitive-and-outmoded-concept on a
crutch!"
