Fire Gem Dragons are a colorful, flamboyant breed often found in hot climates, particularly around active volcanoes. Their broad tails store the flames they breathe, which are colored by the heavy amount of minerals in the water they drink. These dragons come in a variety of colors, and will collect shiny trinkets and stones that match their own coloration. Despite their hoarding tendencies, though, Fire Gem dragons are social and will often congregate in groups and show off their collections while fawning over the stones their friends and rivals have gathered, occasionally arranging trades.

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.

Izuku is a "superhero." While she doesn't possess actual superpowers, she does help around the cave, and she has rescued hatchlings (and other dragons) in peril. With her shiny scales and her catchy catchphrases, she's loved among all the dragons in the cave.

However, every character has flaws. To her, the whole point of being a hero is not to save dragons from harm but is to gain fame, glory, and riches for doing it.
