We know the entities we're facing are interested in evoking fear, and Pyre's performance did that. They made a point of making Gloucester the first stop where he did his show--the decision likely came down from above, from Fenix. He pushed the idea that ADI had something to do with the Smoke and Mirrors derailment 100 years ago, so it might have been his idea of revenge against ADI.

The funhouse, we understand less about, but from what I've heard, the mirror at the center was the focus for whatever happened there.
