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.

The youngest of the little group of mismatched friends, Inu is an honourable dragon, willing to put himself at risk in order to protect anyone in danger. Though he is not above using his blades to punish a certain Bleeding Moon for his drunken bouts of stupidity.

A dragon always willing to learn new ways to use his wings, it is common to see the little Inu begging the Cave Mother for lessons in the ways that humans use swords in combat. Though considering his small size and physical frailty, it is not surprising that she normally turns him down out of fear of injuring him. It doesn't stop him from trying, though.

The reason for his constant insistence is simple: he aspires to join The Saints of the Blade, after being witness to a training match between the leader, Gwyndolin, and another dragon seeking membership. Inu is in awe of the Gold, and seeks to become a member so that he might aspire to be as a noble a leader and knight as his idol.
