Lindworm

A wingless dragon with a serpent's body and two clawed forelimbs, dragging its bulk through fens and barrow-fields and leaving sickness in its trail. Lindworms are slow to anger and slower to forgive, lairing in burial mounds they have hollowed out, and their breath and blood carry a plague that withers crops and fells the strong.
