When Water Dragons mature, they lose the ability to survive on land, entering the water permanently. They are adept swimmers and eat whatever fish are in the lake they live in. They tend to inhabit the same lake for their entire lives, although a few live in the ocean and swim all over the world.

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.

Isaih's name appears to be missing a letter, and that's intentional. He's been in discussions with the GoMA about how his birth name, "Isaiah", violated the OSL clause of their Performance Agreement and that he'd be liable for damages to the party of primary ownership if he didn't take action. These were tiresome discussions and Isaih is a small, simple dragon with not enough of his life to lose over something he thought trivial, so he compromised. He doesn't regret leaving his brethren to come to Aquebecker to do bigger, more impactful things that they won't understand, but he does wish he had read the contract more carefully. When he talks about minor woes to his sapo and tercorn housemates, they usually look confused because he speaks with more jargon and vague phrasing than they can understand.
