Callistana means: Sydney Sage summons a kind of demon from her witch-like Bloodlines series. Although it looks similar to a small chinese dragon, and can move about freely, the body is actually made from quartz. The spellcaster can turn it back into rock and then back again. The caster is the most likely to be the one it bonds with. It bonds to more than one person, however. It’s used to alert those who are bonded to it of danger by making screeching sounds, but it also makes screeching when hungry. Once cast, the spell will last for one year and one day.
