Tri-Horn Wyverns are a mountainous species, living in high altitude areas among rocks and snow. The rough and rugged climate has bred a tough and hardened species, prepared to do battle with both the elements and other creatures. Their most distinctive feature is the three-horned crest mounted upon their head, for which they were named; these toughened spikes are powerful weapons, used to battle against predators, prey and fellow Tri-Horn Wyverns. Both males and females of this species fight for territory and resources, and wear scars with pride. However, Tri-Horn wyverns have a soft side beneath their many spikes. They work in loyal packs, of which they are deeply protective; if one can gain their trust, Tri-Horn wyverns can be powerful allies through the mountains.

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.

Although one of the younger Trihorns, Vexx has somehow managed to earn the honorary title of "dirty old man". He constantly spouts innuendos, shows a leery grin, or makes suggestive comments. Many think that Vexx is actually rather insecure about this whole mating-stuff and tries to hide this behind a mask of bravado, but no one can be sure.

For some reason Vexx is terribly afraid of two dragons from a friendly clan called Bindet Dich An and Deckenventilator, and he avoids their son at Delirium's Academy at all costs. But no one knows why; the Magi and both his parents never showed any interest in him.
