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.

Fish that Swims the Ocean is a fearless dragon who is best known for being one of the best aquatic Rune Hunters. A Rune Hunter is a specialized dragon trained to find treasures and other special things. He's found great sunken temples in great abysses and even ancient stone carvings depicting great human battles in coral. His most commemorative find was a great cavern with the largest pearl any human or dragon had ever seen. It was at least one foot wide and tall and it was tinted a soft blue. It was so bright and shiny that Fish had to cover his eyes the first time he saw it. He brought it back to The Cave and polished it which made it even shinier. Most of the dragons were extremely impressed and they placed it in The Cave Treasure Room, which was already filled with gold and other precious stones and minerals.

   Fish is the twenty sixth dragon accepted into The Cave and is mates with the one and only Claw that Catches Fish. Claw finds it funny that her name says she caught Fish.
