"That's right Mary. A demon is a malicious spirit that resides in, or possesses, an object in our mortal realm. Now, though they need the objects to get here, they also act as a sort of prison, keeping it bound to one place. The temple finds and stores these objects, until we can purify them. That is why most are kept in the Reliquary. The purified objects, however, are usually deemed safe to handle and we like to display them, like the cat and dog statue in the main hall."
