In the southwest corner of Casterfell Woods, players will find the Druid Camp and Castle Ruins at the top of a hill surrounded by Druids. You may have been sent here by Mother Jago to recover her book, or perhaps you encountered this location as a natural part of your exploration of Atomfall.

Where To Find The Church Cellar Key In Atomfall
The St. Katherine’s Church cellar is locked up tight. Here’s where you can find the key in Atomfall.
If you enter the castle, though, you may feel disappointed in how little there is to discover within the cold cobblestone of these ruins. However, if you can find the Druid Castle Key location, you will be able to reveal a secret grotto behind the main hall that leads underground into the depths of the Castle Ruins. This guide explains how to find the Castle Key, and where the Keyhole that grants access to this hidden location is.
What Is The Castle Key Used For?
The Druid Castle Key is used to open a secret door in the main hall of the castle. Just behind the body of a soldier slumped next to the throne at the end of the dining tables, you will see a fireplace. Look for a keyhole to the right of the fireplace – this will open a secret room behind the fireplace, which connects back to the Castle Ruins underground area.
You can get to the underground area of the Castle Ruins by going through a side entrance just south of the main castle entrance, but this shortcut will connect the two and make it easier to return to Mother Jago after finding Mother Jago’s book in the grotto just beyond the fireplace.

Where To Find Druid Castle Key In Atomfall
The Druid Castle Key is not too far from the fireplace and main hall of the castle. To find the Druid Castle Key, Atomfall players should enter the castle via the main entrance atop the Druid Camp in Casterfell Woods, then continue forward down the hall. Turn left at the end of the hall to enter the castle kitchen area. Almost at the end of this room you will see an area to the right that leads to a stairwell.
The Druid Castle Key location is on a prep table close to this stairwell, which leads up to the left side of the throne room balcony area. Pick up the key, then head back to the fireplace to open the secret door, unlock the Castle Ruins shortcut, and find Mother Jago’s book.
