Tercorn Dragons are typically friendly and peaceful in nature. Most individuals are eager to help, and show highly-cooperative behavior. However, they can easily feel disrespected by those unfamiliar with their customs. While the three long horns protruding from their heads may be fearsome, they serve mostly to scare off aggressors, and if an attack is deemed necessary for self-defense, it is never deadly in intention. Tercorn Dragons are quite social and active within their aquatic environment, but rarely emerge on land if not caring for unhatched offspring in hidden coastal caves.

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.

Muscle, though named after a variety of mollusk, also lives up to that name with his masculine charm and obsession with physical strength. He works hard at keeping his muscles well toned by exercising religiously. He flexes this strength mostly in racing and sparring. Muscle loves a good sparring match. He tends to use his arms way more than his horns so fatal injuries in such fights are infrequent. He's also a good sport all around; he loses with grace and treats others well no matter the outcome of the game. At least, as long as he views them as lesser to begin with. Muuscle has a complex about being relied upon. He'll help anyone in need, particularly if his strength will come in handy. Despite his good nature, Muscle is not above showing off or feeding his ego. He retains a noticeable sense of arrogance that he'll sometimes flaunt a little too readily. He never seeks to put others down, not unless he is in direct competition with another. Muscle does not like other built dragons.
