Scimitar-wing Wyverns are a small breed, eating mainly birds and small vertebrates; as such, they lack the large teeth and heavy claws of their larger cousins. They are far from defenseless, however, and are named for the blade-like growth that forms over the first digit of their wings. The wyverns use these blades to defend themselves from any attacker. Their blades are quite strong and can cut through almost any scale or hide.

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.

Assentive is calm and easygoing, even when facing great danger. She isn't confident that she'll escape alive or eliminate the threat so much as she feels that appearing frightened will lower her odds of survival. She does genuinely feel fear but is excellent at hiding it. Assentive's attitude is unique in the Caldera, and others in the community couldn't emulate her cheery demeanor if they tried. She enjoys number puzzles and writes figures in base-14 for fun, using her own made-up symbols.
