The Abbey of the Proletarian

Overman Heinrich,
I left you a copy of The Ancient Music sheet so you might familiarize yourself with the principles I’m employing in this latest variation of Holger’s Device, or the "music box" as the men call it. As you should know, it produces harmonies that render heretical energies or "magic" inert through counter-balancing mathematical principles. Read the book and then make yourself useful by finding us some subjects to test it on. This land is choked with corruption and superstition, so I trust you won’t have to look far.
Signed, High Artificer Amadeus.

“I don’t understand what he means by this. We already have proof that the music boxes work against arcane forces, we have them playing on loop around the Archmage’s cell to prevent escape.” Said Heinrich, placing the letter down on his mahogany desk and sitting in his dark brown leather chair.
The woman sitting across from him sipped from a glass filled of amber liquid, and placed it on a coaster on the desk. “If you’ve been paying attention, you’ll have noticed that most magic has been rooted out of the capital city thus far, so what possibilities does that leave for him to have meant?” She asked, prompting the gears in Heinrich’s head to turn.
He sat forward with both elbows sharply against the wood, his hands up at his face resting at his mouth, fingers interlocked. “The only magic users left in the cities, let alone the nation, would be the clerics and paladins of the Church of Valous. But they’ve been working with us to eradicate heretical magics across the lands, so I don’t see what you’re saying, it’s a dead end.”
The woman smirked and stood up, walking over to the window and closing it so that their voices might not carry. “The church is currently in command of the Spellbreakers of the Abbey, but you don’t think Amadeus prefers that, do you? I think he wants us to find ways to tune the mathematical formulae of the music to disrupt even divine magic, that way the church won’t be able to hinder him when he makes his move. With the way tones and sound shape the very fabric of the world as we understand, there must be a frequency we can play to nullify even the powers of a god, no?”
Heinrich hummed for a moment as he pondered it, sitting back in his chair and falling deeply in thought before opening his mouth. “You’re right. The Abbey has always been in service to the Everyman. Magic of any kind allows men to be easily corrupted with power, and the only way to keep this world fair for every hard working common person is to find some way to nullify the power magic has over them. We will need some clerics from our local denomination to go missing, then.”
