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.

Amnun comes from a long and proud lineage of Wyverns, started by two pairs of Nebulas whose goal was to unite all Wyverns into one big family. Due to this heritage, Amnuns loyalty is not confined to his pack, his mate and offspring. He will defend any Wyvern, even strangers, without hesitating or considering his own safety. However, he does no think that Wyverns are better than other dragons, and he will just as quickly punish Wyverns if he catches them misbehaving.

Because of his strong sense of fairness, many dragons, including ones he defeated in battle (if they survived), seek him out to help them settle disputes.
