Common, they originated in the tropics. Whites are only male, and are only slightly bigger than greens. Since they are opalescent, they can blend into water, clouds, and rainbows. They are the only dragons that can teleport, giving easy transportation to normal people. Personalities vary greatly, as whites are a combination of all colors. They can mate with bronzes Golds, Greens, and Purples. Science definition of powers: Whites are able to open wormholes. They can do this by concentrating their mind to do so (again, with their mind's electricity). However, to be able to open a wormhole, extremely precise calculations must be made in their mind so that they come out where and when they like. This accounts for the mass, also. There must be at least the size of a dragon to be transported or the wormhole sucks something else in with it.
