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.

Kazek's vendetta against magi dragons stretches back to early hatchlinghood and a magi half-brother. Said half-brother was the darling of the weyr—quite unfairly, in Kazek's view—and not even Kazek's growing magic-dampening powers could change this. Worse yet, the magi dared laugh at Kazek's efforts to impress the weyr. Kazek has nursed his petty grudge for years, until it blossomed into the all-consuming desire to see all magi dragons wiped from the earth. He has had great difficulty in converting others to his cause, in part because he remains prone to greatly overreacting to small slights.
