Field Notes —
Real History

Every place, manuscript, and phenomenon in Masters X is grounded in a documented record where one exists. 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 Neolithic stone chambers in Britain, Ireland and Malta. 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.
