Cursed Ciphers: The Record Keeper

Some habits outlive the people who created them.

Every document recovered from the archive carries the same unmistakable opening, a convention followed so faithfully that no one ever thought it could become a weakness.

Sometimes the oldest traditions leave the deepest fingerprints.

Objective: Recover the hidden flag.
