Stone Dragons have a tough outer covering made of a stone-like material. They eat rocks, using the minerals they contain for nourishment and to keep up their stone outer shell. They rarely move, and are the heaviest of all types of dragons. Although they have wings, indicating flight ability, no one has ever seen a stone dragon flying.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Ghulom hatched from the third egg brought to the Dothraki Plains by the human girl Kaerth. Neither bitter like the eldest Varashii, a green, nor spirited like the purple Rhallaena, she has a very slow demeanor: calm, measured, cautious. The other dragons of the Plains consider her the wisest among them. Many a dragon have sought her out in her solitude to lay their troubles to her; and though she may take a few days to consider, Ghulom always seems to have sound advice. Finding it quite difficult to move much, Ghulom can most often be found on the northwest bank of the island, where a section of land fell into the see to form a small cliff face about 20-30 feet high. She spends most of her days gazing off across the sea.
