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.

Isabella Hart is a goofy dragon that just wants to play all day. She enjoys the hatchlings and spends almost all of her time with them. She is known as the "ultimate dragon mother" because she adopts all of the eggs that don't have mothers. She wants kids of her own, but hasn't found her Mr. Right. She and James Hedgrou had a thing, resulting in an egg. However, due to the hatchling number, the egg was accidentally abandoned. This fact haunts Isabella, and she hasn't been able to look at James again. Lately, she has fallen for Dash Hedgrou, who has promised her the future that his father figure never gave her. She and her firstborn daughter, Alexis McKinley, are not very close. Alexis left home the moment she grew up and refused to keep her father's strange last name.
