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.

Tobias Fangor doesn't like fighting and was highly picked on until he became part of the Dragonmorph clan. Before being a Dragonmorph he would allow himself to be physically overpowered by other dragons who, luckily, never intended to kill him. Besides being picked on by other dragons, he was hunted by humans who wanted his power to nullify magic. As a Dragonmorph he is relegated to scouting and can only participate in a few missions because of his breed's ability. This makes Tobias feel like he isn't really part of the clan and he ends up doing risky stunts because of this perceived flaw.
