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.

Much like her closest friend Cumberland Spirit, Cumberland Lake Guardian has been referred to as the "Spirit of Cumberland Lake". This guardian has the duty to keep peace and protect all the inhabitants of Cumberland Lake- from the dragons that reside there to the fishermen who fish there.

This dragon was chosen as guardian due to her pristine lineage and her massive size for a water dragon. She is nearly twice the size of the other water dragons in EG's Cave. Despite her role as protector, she has frightened many other dragons and humans away from the lake due to her haphazardly fashion of swimming. She has been known to accidentally crash into boats and docks causing them to capsize or fall to pieces. Sometimes she doesn't realize how big she really is. Cumberland Lake has faced many problems due to her accidents, but overall she still manages to keep peace and guard an orderly and beautiful cliff-framed mountain lake.
