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.

Matilda, at the beginning of her life, was an energetic and hard-to-control hatchling. When the adult dragons were paying attention to the other hatchlings, she would swim away and end up near human territory. Here is why some dragons call her 'Matilda the Interested'- she was so interested in humans. She would watch from under docks as humans built mysterious structures, which she heard were houses. She watched from underwater as they caught fish with metal hooks attached to string and wooden sticks. When the adults finally noticed she was gone, they'd go into panic. Eventually, they learned where she would go all the time. She always returned home, so they learned not to panic as well. Even though she is mature now, she still watches the humans. Because of this, she has the most knowledge about humanity. Dragons use her knowledge to protect eggs and hatchlings and to avoid them. Some say if you look deep in the water near the dock she lingers in, you might just see her.
