Kohraki Dragons silently stalk their prey, concealed within the thick, rolling fog that blankets autumn forests. They prey on the lost and unwary, luring them close by mimicking familiar voices and sounds before swallowing them whole, leaving no trace behind. Bustling, warm villages have been left silent and cold after particularly foggy nights, their inhabitants having fallen prey to swarms of Kohraki Dragons. After, these dragons disappear as quickly as they come, leaving behind only unease and footprints.

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.

She is usually paired off with her Black Marrow partner, Vassago, since the both of them share a distinct taste for flesh. They are notorious tricksters known to toy with their prey and even threaten the members of their own group. However, those who know them also know that they are both phenomenally stupid and a non-threat to anyone possessing strong enough magic. Gusion is the more dangerous of the two, if only because she isn't as eager to exercise her fear factor as Vassago. She is, however, the least intelligent of her group. She doesn't even use her own voice. She communicates entirely through sounds mimicked from others. She is a voracious creature who thinks exclusively about eating. This is evidenced by how she will refer to others as sweets. For instance, she may call a purple dragon a blueberry muffin or a person a gingerbread man. It can be maddeningly unsettling, especially with how quickly she can down her prey the second they look away.
