Þrymr

In Norse mythology, Þrymr (Thrymr, Thrym; "uproar") was king of the jotnar. In one legend, he stole Mjollnir, Thor's hammer, to extort the gods into giving him Freyja as his wife. His kingdom was called Jötunheimr, but according to Hversu Noregr byggdist, it was the Swedish province Värmland, then a part of Norway.
