Cassare Dragons are known for their magic-deadening abilities. Though not a conscious ability, a large field surrounds the dragon through which magic is passively nullified. This field is strongest near the dragon itself, and falls off with distance. The absence of magic often makes other creatures avoid them, though some will have the opposite reaction and seek refuge instead. It has also caused them to be hunted, as though the field is severely weakened once dead, their bones and scales retain some of the effect. Possessing such an item is considered a necessity by those who expect to face hostile magic.

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.

Fasach Uasal is the adopted daughter of Fasach Luas and Breithe An Chroi. The two cassare dragons took her in when they found her egg at the bottom of the mountain in their territory. Although Fasach Uasal knows she's adopted, she loves her adopted parents very, very much and treats them with the utmost respect. The young cassare dragon is missing a few scales on her tail from a run in with a knight who was searching for cassare scales to fight another dragon. She is very cautious around humans because of this event but will trust those who prove themselves to not be a threat. May213 tends to read to Fasach Uasal on nights the two can't sleep as a way to lull the young dragon to sleep.
