The Athos Codex: Word Puzzle

You are Theodoros, a scholar of Thessaloniki, writing a hypomnema (scholarly commentary), on how Christian thought reshaped the pagan Greek philosophers: how it widened the circle of "us" they had drawn around their own.

One source would finish it: the Forbidden Codex. But it was torn apart generations ago, fragments hidden in the libraries of each monastery on Mount Athos.

Separated, the pages were harmless. Together, they hold the lost teachings.
Your hypomnema has stalled. Every source you need is behind those gates, but they are not for you to enter. So you enter under another man's name.

The synod meets in spring to burn the Codex.
The monks are watching.
Don't be discovered.

Guess hidden words, evade suspicion, and study the Codex before the synod destroys it.

The Athos Codex is a branching word puzzle. Choose your route through the monasteries, manage the monks' suspicion, and complete your hypomnema one deciphered fragment at a time.

A WORD PUZZLE WITH STAKES
Every puzzle begins with a hidden word. You have six guesses to find it. Every wrong guess raises the monks' suspicion. Stay too long, make too many mistakes, and a monk finds you. The run ends before the chamber gives up its secrets.

BRANCHING MONASTERY RUNS
Every monastery is a branching path through three chambers. Each chamber is more challenging and presents puzzles with different word lengths, difficulty and rewards. Decide how deep to venture, when to press on, and when to slip away before suspicion overwhelms you.

TOOLS FOR THE HARDEST WORDS
Discover a scholar's tools, represented as upgradeable cards, to help decipher difficult words. Upgrade them as you progress, and decide carefully when each one is worth using. The right tool at the right moment can save an entire monastery run.

EXPLORE THE REAL MOUNT ATHOS
Travel freely between the twenty real monasteries of the Holy Mountain on an authentic geographic map. See what they look like. Learn their history. Every destination brings new words, new dangers, and new fragments waiting to be recovered.

COMPLETE THE HYPOMNEMA, AND IT IS REAL
Every successful run recovers another fragment of the Codex and progresses Theodoros's adventure in writing his hypomnema.
The hypomnema is the precursor to a real, finished book.
The medieval commentary and the modern book are one work, separated by centuries and completed across them.
The chapters you unlock are drawn from The Circle We Choose, a published work exploring why people who share the same values end up bitterly divided over immigration, identity, and fairness, and how the instinct to protect "our own" has driven both heroism and atrocity.
The full book is available separately on Amazon.
