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 of dragons, Ember Dragons are incredibly loyal and will defend their pack by any means possible.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Yule Log (true to his name) has a weird fascination with eating wood. Typically, Embers will only eat plant matter when desperate, but tree bark is Yule's favorite food. He'll go to great lengths to scavenge it and has been known to scrape some trees bare. His family just sees him as a weirdo, but, since this habit doesn't really bother them, they leave him alone. Yule is not super aggressive or threatening, but he is oblivious to others. He doesn't really care about anyone but himself and will all but ignore everyone around him. Even if he is being directly addressed, he'll pretend he doesn't hear them. The only times he'll pay attention to somebody is if they offer him food or pose a threat to him. Though he ignores everybody, Yule does not take threats lightly. He is a physical brawler in combat, possessing some shockingly tough muscles and a bite like no other. (He does get a workout chewing trees after all.) Yule usually just tries to ward enemies off so he can go back to eating.
