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.

KeenTsunami is a clever Tsunami Wyvern and is great at hunting big fish. She dives down underwater and "claps" her wings to make strong currents. She uses these to divert schools of large tuna so she can grab multiple fish at one time while they are all confused. KeenTsunami would probably get fat if she didn't exercise her muscles all the time while flying and while on the hunt. She actually uses so much extra energy while hunting that she is a very trim Wyvern, despite all the extra fish she catches and eats.
