Tsunami Wyverns are gigantic dragons that live near the ocean. These wyverns can create deadly tsunamis by vigorously flapping their wings directly above the water. They create these waves to catch the eye of potential mates or as a form of self defense, as they are hunted for their beautiful skin. A Tsunami Wyvern’s wings are also helpful in gliding over the ocean without expending much energy. Their colors make it easy for them to blend in with the ocean water, which can be useful while stalking prey. Using their rudder-like tails and webbed feet to dive deep into the water, they can easily catch and eat their fill of big fish. Tsunami Wyverns can be found mostly near island chains.

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.

Quavius was raised with Cashma and Vamiora, though he and the Pink Dragon never had the chance to interact with Vamiora since she was only 'alive' past their bedtimes, Quavius and Cashma were very close friends. Quavius acts like the 'big brother' to many other aquatic dragons in the cave. Especially Alagaa and Squelwie. While the two of them were hatchlings, he had fully matured and took the role of their guardian, helping Riath take care of them when they wandered too far out to sea. Still, he prefers the company of his best friend Cashma. The two usually hang out near the beach and watch him make waves, or they stroll through cities and enjoy the view.
