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.

Mujaki is rather proud of her magic-deadening ability, because she feels it gives her an edge during skirmishes with enemy clans that may arise. She's carefully studied the exact range and strength successions of her passive nullification field, so she can strategize with magic users in the Sylvain clan when they go off into battles. The one thing she is unhappy about is that she can never be healed using magic, which means she needs to be more patient than her siblings each time she catches a cold or sustains a battle injury.
