I'm not well and truly familiar with Air and Earth Dragons.
I'll try and read up on them tomorrow.
I'm not familiar with Dark Dragons either, though I love that concept.

I suggest that we concrete Fire and Ice Dragons, consider Water Dragons, and I'll read upon the other three (Air, Earth, and Darkness) tomorrow.

Perhaps we could spiff up Dark and Light Dragons as primarily magic reliant. What do you think? They could be the masters of magic and the two castes of Elders while the elemental based Dragons are lessers.
