Xiuhcoatl are among the most cunning and dangerous of Dragons. In form they are enormous flying serpents, with long venomous fangs and vast feathered wings. They can also exhale blasts of supernatural fire from their jaws. Individual Xiuhcoatl are on a par with most other breeds of dragon for sheer power, but alone among their kind they possess the ability to take human form without sacrificing any of the strength or power of their draconic shape. This makes them particularly deadly infiltrators, able to work their way into the cults of their enemies and destroy them from within.
