Mythril is something from "common" fantasy which fits dwarves very well.
For those of you who can't stand graphical versions, here's a screenshot from my elf-hunting game (almost every human, even farmers, wear elf bone crafts and a lot of people are living in forest retreats which are highly populated and had a lot of buildings are built, and the only elves left alive are shopkeepers).
