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.

Ace of Sky is the second in the Ace generation. Being a Tsunami Wyvern afraid of water, Sky's had an interesting life growing up in the mountains. She's brought a daily supplement of sea air and sea salt by the mixed-up SkyWing Tevorah, who more often than not tangles up and can't fly, and her friend the Neotropical Dzengal has to take over. And since Dzengal's afraid of flying and rarely does things right, Ace of Sky normally falls into a sick state, and has to be healed by any number of nearby dragons.
