The Hill Dwarves of Krynn come from many different backgrounds and live in many different places. The main difference between them and their Mountain Dwarf cousins is that they prefer to live in the world, not under it. Other differences are the characteristic clothes and the manner in which their beards are worn and trimmed.
Hill dwarves are unusually distant from other races and will not share any of their secrets with them. If secrets are shared, this is known as “breaking faith” within their society.
