Striped River Dragons dwell in clear, deep-moving water. These dragons are playful and active, but wild individuals are very shy and tend to flee at the first sign of humans. They are excellent swimmers and can hold their breath for up to an hour, and are also capable of magic-powered flight for short distances. Their hoards usually consist of shells, smooth river stones, and freshwater pearls; Striped River Dragons often trade objects from their hoard and give “gifts” to dragons or people they consider to be friends. These dragons are intolerant of poor water conditions, so their presence is often an indicator of a healthy river system.

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.

Eslys may not be as magical as her mate, but she certainly knows how to make a splash. Her river winds through the conifer forests of his territory, regularly freezing over and requiring Eslys to break the ice. The stream is so pure and full of light that she doesn't mind. She loves to prank Yzuyx when he comes to drink, popping out of the water and giving him a big damp hug. She makes sure to pull the water off of him with her water magic afterwards, otherwise he might catch a chill. She loves to dance through the sky with him under the aurora during winter and hunt for flowers with him during the brief spring and summer of their polar clime.

Sometimes, other creatures come for a drink at Eslys's river. She likes to pop up and greet them, usually splashing them whilst doing so. Creatures of darkness—who are particularly sensitive to the diluted light mana that flows through the stream—tend to run for their lives when she appears. Most react more moderately. Eslys never means harm.
