A traitor lurking in the ranks

Exploration Stage: Octopus Citadel
From: Violet
Description: After being stranded in the Sheriff's Department building by the fog, I decided to lead everyone instead of the director. The hardest part was putting down the prison riot. One of the officers gave the prisoners the keys to the jail, which are difficult to forge. Find the key and see for yourself!
Completed: If you look at this mechanical key, you'll see how difficult it is to forge. Without this key, there is no way to open the cell door. The Order has succeeded in winning a few Bureau members over to their side by promising them eternal life. They freed the prisoners and took the Order's side.
