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.

Cras has to be the laziest Wyvern in the whole clan. Whenever he is told that he has to do something he will nod eagerly with a friendly smile and ask the dragon until when it needs to be done. And then he will promptly forget about his task until moments before the deadline, or maybe even a few days after. Whenever someone reminds him in the meantime, he will always have good reasons not to fulfill his duty immediately, other tasks that need to be finished first, pressing dates he has to keep, etc.

Still he has quite a few friends among his clan's members because he always has time for a friendly chat or a nice game of dragonballs between friends.
