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.

Blitzing over the seven seas like a powerhouse, an eager mother wyvern accidentally dropped one of her eggs precariously into the crow's nest of a ship owned and boarded by one Insidious Pirate-Captain Black. Kept secret by the First mate, herself. Within a few months, the Tsunami Wyvern broke out of its egg. The small squealing hatchling now practically impossible to hide, it soon became known to everyone on board. For people voyaging, it was a great de-stresser, and they didn't have to worry about its food because they were literally surrounded. Soon enough they had a well-trained, fast, six-ton mass of reptilian flesh as their new fishing net.
