The Mount Holly Estate is a house that is constantly changing, and as you continue to explore and draft new rooms, you will uncover new entries in the complete Mount Holly Directory. Blue Prince players can use this to reference every Room in the game and track their progress toward the Explorer's Trophy achievement, which requires you to fill out the Mt. Holly Directory.
