Editing Periodic Table of Dragons (section)

==Uranium 92==
Uranium and Plutonium dragons are very closely related subspecies, sharing a common genetic pool and often crossbreeding. They are profligate artists, crafting beautiful red, green, and yellow glass sculptures by mixing glass with their ground up scales. Colorful ceramics are also extremely popular. 

The two species can live almost anywhere, heated by an internal warmth that never ends. Red dragons can breathe hotter fire, but a Uranium dragon's heat is something altogether different. The two species are too heavy to fly, their wings having become vestigial cooling devices.

Though normally peaceful, Uraniums and Plutoniums can harness their internal fire in a very different way than most of the other Radiant Metallics. When angered, they can release a blast of heat and light of truly immense proportions, enough to shatter a city's walls or incinerate an army, and they can sustain this force for hours if need be. 

Most civilized nations treat them with some wariness, and in general, the Uranium and Plutonium species keep to themselves. Some few youngsters have been tempted by the promise of wealth and power though, and serve as unstoppable engines of war with which to conquer neighboring countries. It is unclear what this imbalance of power may lead to, but kings and emperors are emptying their treasuries to secure these dragons' services. 

What being used as siege engines may do to the dragons' mental state in the long term is an open question.
