a malicious form of Dwarf from Northern England. They revel
in tricking people into dying.
The dwarfs of the Norse, they live in the rocks and hills and are
brilliant metallurgists, and are smiths for the gods. They were once
the maggots in the giant Ymir's flesh, and became the duergar when
he died. They became the partakers of human knowledge, and although
they resemble man in most ways except for their short legs, long
arms which almost reach the ground when they are upright, and grumpy
dispositions, as well as the fact that they turn into stone when
sunlight shines on them.
