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.
Vault of Echoes remains part of the Neohm Labs public surface while the portal and AEN continue to mature.
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 a different style of reasoning challenge.
Corridors
- Lanterns of Chance - probability and risk
- Council of Witnesses - logic and testimony
- Scroll of Lemmas - theorem webs
- Labyrinth of Forms - geometry and structure
The series will keep expanding as the lore system and puzzle architecture continue to evolve.
How to read it
Treat it like a codex: attempt, reflect, return. Many puzzles reward a second pass after you have built the right mental tools from earlier corridors.
This is designed to be fun, but also to train the same muscles Neohm Labs cares about in education: step-by-step reasoning, checking assumptions, and communicating a solution clearly.
