Ember Dragon

Ember dragons were released on the 10th of October, 2010 alongside Harvest dragons. Ember dragons are uncommon and currently have no breed specific action. When Ember dragon eggs crack, the cracks are red, as if the eggs have lava inside them.

Official dragon descriptions
Adult:

"Ember dragons have a great affinity for hot environments. While they themselves are not hot to the touch, their tendency to lurk amongst smoldering ashes has caused many to believe they are fire-starters. Their dully glowing markings serve many purposes; acting as a means of identification between individuals, as an important part of mating displays, and as a way of showing aggression. The long, low build of the breed makes them ungainly in flight, and the thick fleshy membranes of their wings hinder them further. As such, it is rare to see an ember dragon take to the air. Ember dragons are also not particularly sociable; females tend to be defensive, whereas males are more aggressive. Once they have settled with a particular group dragons, ember dragons are incredibly loyal and will defend their pack with any means possible."

Mature Hatchling:

"Aww... It's a cute baby dragon. It glows brightly, and seems to prefer warm areas. And look! It's grown its wings! It must be close to maturing."
