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.

Duni is a gentle giant and only strives to do good. She is playful, silly, and a nice tempered wyvern but yet she's really still just a little hatchling on the inside. Duni loves the ocean but she also likes to explore other biomes, but none can compare to a place with a lot of water and is big enough for a large dragon. Sometimes Duni is a bit scatterbrained and will sometime do things without thinking, but she tries her hardest to make up for an little errors she may cause, though little is an understatement. As if typical of her breed, Duni seems to like using her ability of creating tsunamis, but she tries to keep it for only important cases, such as getting food, but sometimes her plans backfire and causes more trouble than help. Duni was also adopted by the Bluna Stellaluna and she likes to help out with the other sea hatchlings, and she loves them all.
