Bright-Breasted Wyverns are a breed of dragon easily recognized by their bright red markings. They are a small breed, only the size of a full-grown man. However, they have developed poisonous barbs on their feet to make up for their size. Their coloration is used to warn off potential predators of the danger, and is also used to attract mates. They are very social, and can often be seen preening in large groups.

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.

Zach is pretty infamous in Recila's Cave for being a playboy—girls flock to him, gossip about him, sigh longingly in his direction, the whole shebang. This isn't intentional, of course. It's merely that he's an exceptionally handsome dragon with a—surprisingly natural—gentlemanly personality.

Zach finds this very annoying, especially as he's told them all that he is NOT interested, that he's about as straight as a Misfit's flight path, but they just laugh it off and assure him that, one day, he'll 'see the light'.

At the moment, Zach has taken to sleeping in Kon's Cave, simply because his fellow Bright-Breasted Wyvern is too busy preparing for doomsday to kick him out.

As of late, Zach's developed an infatuation with Null, an observant, but shy, Falconiform dragon, and has decided to try pursuing him. So far, he's only good friends with the other wyvern, but he'll keep trying.

The girls of the Cave are decidedly put out by this, but haven't given up yet.
