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.

Running in the River, or Running as the members of his cave refer to him as was the first dragon to be documented by the proprietor of the cave.  In spite of being confined by his nature as a water dragon to the underground lake inside the cave, he is the leader of the dragons in the cave, and thus is looked to for wisdom and advice.  However, the squabbles between the other members of the cave occasionally annoy him, and thus he travels through the underground river that connects the underground cave to the outside world to escape from the realities of cave life.  All the same, he enjoys the life he now leads as the leader of the cave and the ability he has to regulate the activity of the other members of his cave.
