HISTORY: These dragons seem to have originated in England, and are said to live in forests and wells. They love any place near water.There are many famous worms in England's history, the most famous perhaps is the Lambton Worm. This is about an Heir to Lambton Hall in England who caught the small worm, but thought it too ugly to eat, so he thew it in the local well. Over the years the worm grew to enormous proportions and left the well to harass the locals. When Lambton came back from a war to see the horror he had created, and was told by witch he must slay the worm, but also must kill the next creature he saw. He slayed the worm, but unfortunately, the next living creature he saw was his own father, of whom he could not kill. It was said that the Lambton family was cursed for the next nine generations, and doomed to die abroad, and never at home.
