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.

Nexusa does his best not to offend any of the other dragons in his land. Though his powers means most dragons can't make a meal out of him he'd rather not make too many enemies. Even if he avoids most dragons he isn't really alone, animals tend to hang out around him happy to be away from the magic of more aggressive dragons. This can sometimes get a little annoying, but at least he has someone to talk to. He also has his Nocturne mate who is always happy to share a night time flight with him.
