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.

Bodies crunched under Rayuj's paws as he strode through the Necromancer's army. He didn't really need to do anything more than that, as his natural anti-magic field did all the work, cancelling the animation spells that drove the warlord's victims forwards towards the flock's territory.

A sorcerer shrieked in pain as Rayuj approached, incinerated by the flames of his no longer docile mount. Arrows hissed through the air, fired at the Cassares and Desipis by the living soldiers that followed the undead. Most did not reach the ground, destroyed in mid-flight by the magic of Rayuj's flock-mates. A single arrow penetrated, piercing Rayuj's wingsail in its descent. He flicked the injured limb and hissed in displeasure. Whites were as affected by his field as any other dragon, and the pastes they used to heal Cassares smelled awful.

There were no more bodies dropping in front of him, only a wide gap then living humans. Rayuj sprung into the air. His job was done, time for him to leave.
