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.

After seeing the cave's Vocaloid Dragons rising in popularity, The Dramatic Song decided to write a song of her own to try and achieve stardom. Unfortunately she was unable to think of anything to write about. Then she hit upon a bright idea: she would write a song about the fact that she wasn't very good at writing songs, make sure that it sounded really dramatic, and then find dragons that didn't speak her language to sing it to. Her strategy has proved mildly successful; as she actually sings, "This song sounds dramatic but I'm bad at writing words. If you don't understand it, this probably sounds pretty good." When anyone asks her what the words mean, she always tells them that a perfect translation does not exist, but that it's basically about fifty billion rainbows and the sun and the moon setting at the same time. Although OMG A Double Rainbow is rather a fan of Dramatic's due to this last point, the other Vocaloids are not fooled and refuse to let her join their clan.
