The dragon is not a magical beast, except insofar as it enjoys adding magical objects to its hoard. In theory, a dragon could do just about anything it happens to want to do, but in practice, what it wants to do is gather a great heap of treasure and lie on it, sleeping or drowsily counting and sorting every last gold coin. It is a truly fearsome beast in its prime, capable of gulping down any number of second-string heroes, but despite the claims of certain popular songs, dragons don’t live forever, and sooner or later someone is going to leap boldly past the flames and drive a sharp point into its heart. Dragon Time is the age when abstract concepts, heaped up like gold in a dragon’s hoard, dominate human consciousness and suppress magic—for a time.
