Wyrm
The Limbless Ancient Dragon
The wyrm is a primordial limbless and wingless serpentine dragon from Norse mythology and English legends. From the Old English word for serpent or dragon, it preserves a more ancient form than later chromatic dragons or wyverns. Most famously, Norse Jormungand—the world serpent of Midgard—encircles the entire human world by biting its own tail, fated to perish alongside Thor at Ragnarok. English tales of the Lambton Worm and Lyminster Worm tell of village-terrorizing local monsters with massive bodies and deadly venom.
