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.

Deter (other names are; Dettur, Dexter, Dexur, The Loner, The Inscrutable) is a veritable lone wolf. He has a very intelligent appearance and is quite big for a Cassare Dragon. His guarding skills are impressive and his fighting skills make up for his lesser hunting skills. But Deter isn't known to share his knowledge or wisdom: he's more of the reserved kind. He is loyal and demands everyone be loyal too; he doesn't accept disrespectful behaviour toward elders and leaders. He frantically sticks to the rules he laid upon himself and the others. Sometimes, with his maniac side, he makes believe he could be insane. It is said he would have a mental breakdown if he did not have the rules to stick to. Deter only asks the best of the others and isn't really interested in gossip and female attention.
