A large brass key. I wonder what door this key fits?

The Castle Gate Key is a key in Haunting Ground. It is found in the room with the Metal Boots by using the REST plate key, and the player must save Debilitas and get the Smudged Key. The Castle Gate Key is only found on a second or more playthrough. It allows the player to unlock the main castle entrance and receive Ending C.


  • If the player has retrieved the Castle Gate Key from Debilitas, it is possible to turn it into a Magist Medallion by placing it in a refining machine after Hewie rescues Fiona Belli from her cell in the Water Tower.
