The most cunning and strict of the lesser dragons, rock serpents are always looking out for themselves above all else.   A rock serpent has a face and body made of obsidian, stone, and igneous rocks from its years of eating and burrowing down in the depths of the world. By the volcanos of the great seas, its semi-translucent blue skin ending at the base of this mighty beast tail the earth of the depths of the world being their one true protection from there great predators. Over the years their body absorbs the many minerals on their body and that they have consumed bringing a sharp and near indestructible obsidian tail to serve them in the creation of there lairs and tunnels. When a rock serpent is in its wyrmling years where they have no protection serving them they will often cling to their fathers and devour the coating of rocks and ores they have amassed to survive afterwards they are cast out or swiftly eaten. Over the years as a rock serpent ages, the eyes become gems called Worlights while their bodies start growing at an accelerated rate usually resulting in their death from their own coating however if they can survive they become something known as world devourers.
