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.

Rheikanio is normally an introverted dragon, shy to any social activity with any creatures other than the dragons he grew up with. Even then, he usually doesn't show his face. Most of the times, Rheikanio stays in a nearby cave, coming out only occasionally. Just because he's a bit of a recluse doesn't mean he doesn't care about the other dragons or Vinny. In fact, the millisecond that danger the others rears its ugly face, he'll spring out from the cave to fight against any assailants. Rheikanio is not only quick to fight for the others, but he is also very skilled at it. He can shred up an unaware enemy with his horns and claws within a minute. Luckily, for the sake of any creature passing us, he rarely has to do this. Other than being totally willing to viciously fight for his friends, Rheikanio is quite peaceful, although his telepathic words may be a tad bit blunt and easy to misconstrue. Somebody who has never met him may confuse his mental wording for something more offensive.
