Summary
From the Onyx Path catalog:

"The Exarchs are real.
The Dethroned Queen,
cast out of the Heavens by wiser gods than she,
proves they’re real. You can doubt her existence,
but doing so only proves your ignorance.
The Dethroned Queen was real.
Soon you’ll see.
Soon you’ll get it.
Then you’ll believe."
