A Burrowing Worm-Dragon. This design was inpired by real life animais like amphisbaenas; and caecilians and the idea that if Dragons could evolve, they could evolve to something less complex and more specialized. This species lives in tunnels created by themselves and in caves or dungeons, they lost their ability to fly and to spit fire, which doesn't make them less dangerous. They can move incredibly fast while digging in dirt or sand and can break rocks with their powerful claws and are often said to cause small earthquakes. They are very agressive hunters that guide themselves mainly by the smell and touch, compensating for their poor vision.
