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.

Koshi prides himself on being able to throw the best parties, but he's always been somewhat of a control freak when it comes to planning. He's incredibly meticulous in decorating the venue and deciding on the catering, and will often chase away anyone who tries to help outside of his directions. Koshi strives to add some sort of unpredictable element to all of his celebrations, whether spectacular feats of magic for the entertainment or exotic foodstuffs for guests to nibble on. His family hopes that he someday finds a partner or at least an apprentice to help take some of the party planning stress off his shoulders, but in the meantime, they're content to happily enjoy his boisterous coastline beach bashes and refined underwater galas.
