Blue Dragon
Dragon · Huge
Blue dragons rule hot deserts and badlands, burying themselves in the sand to burst out under caravans with a crack of lightning. They are proud and territorial, and they demand tribute from the oases and trade routes they claim. Desert travellers learn to read a sudden smell of storm on a clear day as a warning.
