Deep Sea Dragons, as their name suggests, spend most of their time in the darkest depths of the sea. They have a bioluminescent dorsal spine that serves to attract prey and communicate with their own kind. As with many deep sea animals, they generally eat whatever they can manage to bait. They rarely leave the ocean floor, surfacing only during breeding season. When they do choose to travel to the shallower depths, they avoid bright lights and will only come up far away from shore.

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.

Utau Chara's egg washed up on the rocky beach near the mountain. When she hatched, she was moved to a pool of saltwater in a damp cave. Utau is often visited, especially by Jorick and Tadese Daidouji. Utau is, despite her appearances, an innocent child-like dragon. She is a go-lucky girl and often doesn't notice things and moods. Utau is a singer and sings in beautiful dragonsong that echoes down into the valley below the mountain where Arcait's village is. Many of the Crystal Cave Clan's dragons fly in for concerts that happen once every moon.
