If you have spent time exploring the druids castle in Atomfall, you will have likely found that there is a secret entrance behind the fireplace. There is a lock with a key hole to the right. If you are looking for the Atomic Battery here or for Mothers Jego’s book, you will need to gain access to this secret area.
The key is found within the castle itself, you wont have to look too far. From the fireplace, turn around and take the path to the right side of the room. This should lead you to the kitchen area of the castle.
If you look around the kitchen for a while, you will come across the key sitting on top of a cooker where the food is being prepared. The screenshow below will show you a better shot of where the key can be found.
Once you have this key, you will be able to head back over to the fireplace and use it in the key hole/lock to the right side of the fireplace.
