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.

Tune is a member of a group of Water Dragons who reside in a large lake. He is a helpful dragon, having the innate ability for finding others who have situations that need to be solved. He has the odd habit of pulling his lips up to smile like a human, which actually looks quite frightening to land-living beings but is normal to the other Water Dragons.

Like the rest of his pod, Tune can use his voice to create songs. Using whistles and purrs, Tune's music is light and bubbly, with smooth rhythms and a clean flow. He sings for anyone who wants to hear him, soothing flared emotions with ease. When he is alone, the dragon will sing for himself as loud as he can. Tune likes to hear when his voice echos around him.

Tune is a loyal friend to the leader of the group, a dragon named Pern. He is always hanging out around him, telling him to take small steps forward in fixing a problem. Sometimes, Tune sings little snippets of music to his friend, hoping to ease his mind.
