@Remus2Sounds like the way to go, I approve.
All you need is a master with a copper angel, be it in a music box, on a candlestick, or maybe as part of a chess board. If he can get someone to pay close attention while aware of the angel he can convince them of anything to the point of supernatural effects. That's where the Things come from. The gun that can't be aimed at the master. The bracelets of submission. The hoodie of invisibility. The lighter of blackouts. All of it.
If he's bad at explaining or the listener is bad at comprehending that misunderstanding gets built into the Thing.
