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.

Great Tsunami spends her time looking for dangers in the sea and catching big fish for  the cave. Because her diet consists mostly of big fish she doesn't take much from the cave stores, but she also brings back plenty of fish to add. She has earned a taste for deer though as all hatchlings were taught to eat a little of everything that they could stomach.
