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.

Infera was picked up right outside of a cave filled with Ember dragons. The egg appeared to be abandoned, but was close enough to the others it might not have been. Either way, the Castle Master stole her away, managing to get away with only first degree burns. When she hatched, the warm hatchling kept mostly to herself, though now when she's confronted she is almost always in a bad mood, snapping at whoever thought it was a good idea to talk to her. The only ones she obeys are Edin and the Castle Master, having no choice unless she'd rather fend off the ferocious Seragamma.

The lumbering dragon can often be found below the castle in the dungeons, her skin's glow flaring in the dark, just barely noticeable in the looming shadows. Infera has seen much go on beneath the surface; horrible, unspeakable things that not even her companion Razous knows of. Such things are the reason she fears the Castle Master more than any dragon alive.
