Aqualis Dragons inhabit the shallow seas of Valkemare, preferring to make their homes in coral reefs. Due to their need to return to the surface to breathe, they avoid deep water unless absolutely necessary. Although they are quite drab when first hatched, prolonged contact with salt water causes their skin to become bright and iridescent. This vibrancy, when combined with quick movements, confuses the fish these dragons prey upon. Nomadic males travel the length of Valkemare’s reefs in bachelor groups, while females tend to claim a specific area as their own. A group of males will herd a school of fish into a female’s territory, and if she is seeking a mate, she will join the hunt. Once she has eaten her fill, she will choose the most skilled hunter to be her mate.

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.

Trout has all the signs of an alpha male. He's bold, brash, listens to no one but himself, and constantly gets into scuffles with his brother in-law, Teal. The two of them have an on-going rivalry over Lagoon, Teal's wife and Trout's sister. As anglers, they are in a constant state of trying to one-up each other to impress Lagoon and the rest of the family. They can be very childish and petty, both of them, but this fighting is ultimately rooted in Lagoon's affection for both of them. Trout cares deeply for his sister's safety and does not wish to see any harm come to her, physical or emotional. Teal feels this way as well. So, they end up accusing the other a lot of hurting her. Obviously, Lagoon herself gets very fed up with their bickering, though she does love both of them in different ways. The one thing they can agree on, however, is Lagoon's safety. If ever she finds herself in peril from someone else, the two will call truce and work together shockingly well.
