Dragon "large scale-armoured egg-laying fire-breathing carnivore, not to be confused with the sea serpent of the Central Ocean or the taniwha of Quilth. Dragons are not related to the colony creatures of the Swarms but are related - distantly - to the phoenix and the basilisk, and - very distantly - to the platypus. There are three types." [I p. 45]. III p. 337 A dragon, any dragon, is much more than a bundle of claws and muscle mass. Dragons are used by something - we don't understand what, and we don't understand how - to project itself into what we think of as our world [DZ].

Dragons are afraid of mice.
