A kind of demon summoned by Sydney Sage, a witch in the
Bloodlines series by Richelle Mead.
It looks like a palm sized
chinese dragon and is able to move around, but is made of quartz. It can be turned back into a rock by the caster of the spell and back again. It bonds to the
first person it sees, which is usually the caster. If more than one person is present however, it bonds with both of them.
It is used to warn those it's bonded to of danger and by screeching but also screeches when it's hungry.
The spell lasts for a year and a day after the cast is made.
