In Norse Mythology they were a subterranean race of craftsmen.

In Norse Mythology, they were either the Frost-Giants or Mountain-Giants, and were terrible magicians who lived at Jotunheim, engaged in contest with the gods, and would shatter the cosmost at Ragnarok.

In Norse Mythology, they were the "choosers of the slain," female warriors who selected brave mortal fighters who died in battle to live in Valhalla in Asgard. Attendants of Odin, they were also immortal waitresses that refilled the drinking cups in Valhalla. They were visible only to men about to die fighting.
