Dungeons and Dragons Lore: Linnorm Dragons
Known as the Nordic dragons due to their origin in the folklore of the vikings, Linnorms are some of the most powerful, ancient, enormous and evil of all dragon kind. Many are descended from legendary serpents such as Jörmungandr and at least one of them can go toe to toe with Tiamat or Bahamut in the Dungeons and Dragons roleplaying game.
