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.
Þrymr was foiled in his scheme by the gracefulness of Heimdall, the cunning of Loki, and the sheer violence of Thor. Thor, son of Odin, later killed Thrym, his sister, and all of his jotnar kin, which had been present at the wedding reception. The poem Þrymskviða gives the details of how Thor got his hammer back. Bergfinnr is a son of Thrymr, the Giant of Vermland.
In the Dungeons & Dragons role-playing game, Thrym is the lord of the frost giants. He is a god of cold and ice, as well as a deity of magic.
Thrym was first detailed in Deities and Demigods (1980).
Thrym was detailed in the 2nd edition AD&D book Legends & Lore (1992), including details about his priesthood. His role in the cosmology of the Planescape campaign setting was described in On Hallowed Ground (1996). His role in the giant pantheon of the Forgotten Realms setting is detailed in Giantcraft (1995).
Thrym was described briefly in Defenders of the Faith (2000). He was detailed in the third edition version of Deities and Demigods (2002). His priesthood is detailed for 3rd edition in Complete Divine (2004).
Thrym is a hulking menace, appearing as a mighty frost giant with white eyes, blue hair, and a constant snarl. He can plunge any part of the Prime Material Plane into a state of extreme cold. His animal is the white dragon. His holy symbol is a white, double-bladed greataxe.
Look at me walking the streets at 3 a.m. and you're saying what a crazy fool I am
But the one I love is out tonight with him somewhere making love at 3 a.m.
I need a drink but all the bars are locked up tight
A lonely man gets mighty thirsty late at night
I won't ever kiss her sweet sweet lips again this old world's an awful place at 3 a.m.
[ steel ]
There's the river here's the bridge it's too late now
I've got nothing left to live for anyhow
In the news they'll say he couldn't even swim and he gave his love for love at 3 a.m.
