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.

Despite having a feminine name, Lydonna the Brave is considered a myth wherever he goes, most often spoken of in witches' circles. He is rumored to have faced off against one of the most vile warlocks in Valkemare, and although the details on Lydonna's victory are muddy, most conclude he ended up consuming the terrible man in order to prevent the spread of his evil magic, saving hundreds of lives in the process. This is why today, Lydonna's worshippers, as few as they are, seek to prevent Cassare Dragons from being ruthlessly hunted for their bones. They advise people instead to raise and care for orphaned Cassare hatchlings and eggs.
