A dragon is a type of lizard-like animal lifeform]. Creatures of this specific type are not believed to have evolved on Earth, but the general description of such an animal exists in Human mythology. Humans have since discovered actual dragon-like creatures living on other planets.

Hebitian tombs often had statues of a sleeping toj'lath, representing a dead ruler being wakened by a dragon. (ST - New Worlds, New Civilizations short story: "The Glories of the Hebitians")
