Delivered twice monthly over 12 months by Gravepost Jack himself. Each envelope contains evidence, medical records, newspaper clippings, and artifacts that shouldn't exist.
Every letter conceals secrets. Decipher the codes, solve the puzzles, and unlock exclusive video content that reveals what really happens in the basement levels.
Scan QR codes to access terrifying video sequences, security footage, and POV encounters with the creatures that hunt Ravenwood's corridors.

Surgical masks hide faces that have been altered beyond recognition. They stand in the darkness, heads tilting at impossible angles, waiting for you to make a mistake.
Fast. Relentless. They climb the trees and snatch prey from above. The patients know the rules: never go outside after dark. Never look up into the branches.
This isn't just mail. It's a one-of-a-kind immersive adventure that took over 16 months to create.
Medical charts with injection sites mapped on human diagrams. Patient files marked "CONFIDENTIAL - PROJECT BLACKBURN." Newspaper articles about staff who went missing. Photographs that show things that shouldn't be there. Every artifact is meticulously crafted to pull you deeper into the nightmare.
Challenge your mind with crosswords, word searches, and intricate mazes hidden throughout the letters. Each puzzle reveals clues about what's really happening in Ravenwood. Perfect for thrill-seekers who love escape rooms and alternate reality games.
