This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Dvergr (Norse)
Dvergar or Norse dwarves (Old Norse dvergar, singular dvergr) are creatures in Norse mythology. They are associated with rocks, the earth, craft and metal work, wisdom, and greed. The dwarves came from maggots that formed on Ymir's skin as he was killed by Odin, Vé and Vili. Odin transformed the maggots into dwarves. It is said that dwarves are blacksmiths and built weapons for war between the gods. Some say that dwarves and elves are the same thing.
The term dwarf (Old Norse: dvergr) denoted a species of fairy inhabiting the interiors of mountains and the lower levels of mines. Dwarfs were of various types, all of small stature, some being no more than 18 inches high and others about the height of a two-year-old child. In appearance they were sometimes beautiful, but more usually they resembled grave old men with long beards and, in some cases, humped backs.
