Found within the mountain realm, the luster dragon has become a bane to treasure vaults everywhere. Known for their gluttony, luster dragon's diets consist of gold, silver, and other rare metals. Possessing a rubbery skin, they are able to fit copious amounts of treasure within their stomach without fear of puncturing their own stomach lining. Due to their girth, they can become quite clumsy or oblivious to their surroundings. In some cases they have been known to get stuck or lodged in tunnels after a heavy binge.

An Idea that I had for a dragon variety that will eventually be worked into a book.
