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.

Far above the sea, far from the cave, soars a lone tsunami dragon. Darth seldom visits the cave but whenever she does, it's always memorable. One set of hatchlings tell of the day Darth arrived, looked at them, and proclaimed, "Luke, I am your father." Since none of them were named Luke, and Darth was a female tsunami, the hatchlings were all baffled by this outburst and quietly scuttled away to the opposite end of the cave. Darth quickly left, too, and returned to her soaring over the ocean, leaving no one the wiser as to what she had meant.
