"safe room"

Inside my story, I mentioned about there is a room the boy get inside, the room full of magical power that can protect him. I did find something useful.Those charms and things that can make bad spirits away.

this image I have found it online.

From image above I can see that there are quite many stuff can make bad spirits away. So roughly I have some idea how to put those stuff inside the safe room.

The boy playing alone in the room A, after he realize the shadow.. He run toward to the Room B

The room window pattern is pentacle,the light outside will get through this window and form the shape on the floor and there is an angel statues in the room .
