A lore-infused puzzle codex for rigorous reasoning.
A puzzle-book series created at Neohm Labs — built around “corridors” of challenge: probability, logic, theorems, and form. Read Volume I below.
Note on naming: “Vault of Echoes” may share a name with other works. This is an independent project; we’ll continue refining subtitles/series branding to disambiguate when needed.
The Vault accepts only what survives a later reading.
A codex of puzzles with lore threads and structured difficulty — meant to reward revisiting.

What’s inside Volume I
Volume I is structured into corridors — each corridor is a different style of reasoning challenge.
Corridors
- Lanterns of Chance — probability & risk
- Council of Witnesses — logic & testimony
- Scroll of Lemmas — theorem webs
- Labyrinth of Forms — geometry & structure
(We’ll keep expanding the series, experimenting with format, and iterating on the lore system.)
How to read it
Treat it like a codex: attempt, reflect, return. Many puzzles reward a second pass after you’ve built the right mental “tools” from earlier corridors.
This is designed to be fun — but also to train the same muscles we care about in education: step-by-step reasoning, checking assumptions, and communicating a solution clearly.
