Everquest 2: You lift my draggin' heart .....

Jindrack gave us some insight into the habits of dragons today:

Generally a dragon's breath is reflective of that element, but not necessarily, and breeding could vastly associated one breath type with a completely different scale color. All other dragon colors and types derive from the intermixing of these types, except for the law prohibiting the mating of dragons of directly opposite elements; Red-White, Blue-Black.
