Thora Borgarhjort(Þóra Town-Hart or Þóra borgarhjörtr)receives an adorable baby lindworm as a gift from her father Herrauðr, the Earl of Götaland (in Sweden).
Alas the lindworm grows and takes Thora hostage, demanding to be supplied with one ox a day (or more).Thora is eventually freed by a young man in fur-trousers named Ragnar, who then obtains the name of Lodbrok ("hairy britches") and becomes Thora's husband.
What happened to the Lindworm? It was of course killed by Ragnar.who became a great hero. He appears in many legends and folklore tails and it is beleived his story is based off viking sagas.

The lindworm was like a giant snake, sometimes it had frontlegs and sometimes also wings (although that was not so common in scandinavian lindworms, more so in England, then they were called wyverns and France, vouivres).One can for example see lindworms in viking runestones.
There are two forms of lindworms, one is like an enchanted prince in disguise, and gave fortune if you met one. The other was very dangerous, like an evil dragon, it moved by biting it's tail and rolled like a wheel.

Technical stuff: PhotoshopCS2 about 40 hours. No special reference used, except for my hand holding my daughters plushie in front of the mirror. For the scales I found a texture that I used at CG textures [link]
