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.

AquariusFinn is a quiet dragon who enjoys staring for hours on end into the lake she calls home. While some say that she's vain, she claims she can see the future in the water, and will offer to tell your fortune. While her predictions don't usually come true, she persists in saying she can see the future in her reflection and continues to look into the water every day.

Although they come from totally differnt environments, she thinks highly of dark green dragons.  It is because of them that she can live both in her lake and in a spring inside the Brood's cavern that was expanded by TendrilMaw and TetrusFirma. They created a tunnel underground so she can swim between homes and expanded the once small underground spring so she could live in it when her lake turns to ice.
