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.

Kako the Mischievous is so named because of her strange method of attack. Rather than simply chasing prey down, Kako makes an initial, brutal strike from either the side or behind and runs to hide, as if she were "playing" with her opponent.

She often attempts to cause damage to the surrounding area by toppling any objects such as trees, large rocks, or even small human structures in what is either an attempt at distraction or an attempt to crush the foe. This proves especially effective at night, when her black coloration aids in camouflage. However, during the daytime and in open spaces, this bizarre attack pattern becomes pointless theatrics.

In her pack, Kako seems to be somewhat uncooperative. She either lags behind or runs ahead of the others, and doesn't coordinate with others too well beyond determining a target or a general hunting grounds. This and her odd behavior has lead to mild infighting, though the pack seems to believe that she is worth the trouble.
