Spotted Greenwings are relatively small nocturnal dragons. Easily recognizable by the fleshy appendages growing off of their head and rump, they are most commonly seen in forests at night, leaping and soaring from tree to tree. While generally social, spotted greenwings are very quiet and rarely make any sort of vocalization. Their bodies are unusually warm to the touch, though they are unable to breathe fire. Greenwings are voracious feeders and will consume nearly any living thing that they can fit in their mouths.

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.

Her name means "Moss" in Japanese. She is a daughter of Hanuke and Kuroi-Yimei. She grew up alongside her cousin Kirei, and the two are best friends. When they were little, hide-n-seek was Sentai's favorite game. Of course, she has always been much better at hiding than Kirei, who's golden scales glitter in the smallest amount of light. Sentai still loves to hide, but now she hides so that she can observe wild animals very closely without being detected. Both girls have always been very adventurous, and love to go exploring. That's how Sentai met her mate, Genshirin. The two just so happened to be exploring the same bit of jungle, when they ran into each other. They decided to keep each other company, and together they found some ancient ruins hidden deep in the jungle, and they also fell in love. They are so in love, and always will be.
