Field Notes —
Real History
Every place, manuscript, and phenomenon in the Masters X Trilogy is documented and verifiable. SubTropolis is real. The Strahov Monastery is real. The Voynich Manuscript sits in Yale's Beinecke Library. The 111 Hz standing-wave frequency has been measured by acoustic researchers in stone chambers on four continents. These Field Notes are the documented record — real history, honestly told, that opens onto fiction.
The fiction is the payoff, not the disguise. Real places, fictional events.

The fiction is built on all of this.
The Masters X Trilogy follows what happens when a fired Kansas City security guard inherits 30 years of classified acoustic research — and follows the cross-references into a sealed Prague crypt.
