Acquired: This quest is triggered while exploring Lud’s Holm. You will also find the quest during part of the Treehouse questline.
Objective(s):
- Cleanse the Doors of Your Perception

- Neutralize the Cultist Priest
- Leave the Mystery House
Cleanse the Doors of Your Perception
To enter the Mystery House, you will need to consume a Histoplasma Mushroom to open the door.
Find the Source of the Strangeness Without Being Seen
Before you enter the Mystery House, know that if an enemy spots you while inside, you will be kicked out of the house and have to start all over again. The best way to complete the quest is to take your time and knock out each enemy as you come across them. The below path assumes you will also be looking for the Ephemeral Lines while in the Mystery House as part of the Treehouse quest.
As you make your way to the front door, there will be two enemies to watch out for. Once you pass through the door, take a right and crouch walk under the planks blocking the doorway. This leads to a hallway filled with debris. From here, head through the kitchen into the dining room while keeping an eye out for the enemy that is patrolling this area. After entering the dining room, turn left and follow that hallway while keeping your eyes peeled for another enemy patrolling. You will pass the library and bathroom as you walk down the hallway taking a right once you reach the end to arrive at a door. Head through this door to enter a big open room with a piano and to sets of stairs leading up to the second level. Head up the stairs watching out for the 2 enemies that patrol it. Head to the room set up like a church with an enemy facing the wall to trigger a cutscene.
*Here is where the ephemeral linens were for me in the Treehouse quest:
- 1 on the counter in the kitchen next to the stove
- 4 in the dining room closet (first door on the left in the dining room)
- 3 on top of the bookshelves in the library
- 4 in the bathroom closet
- 1 on an end table in the piano room
Neutralize the Cultist Priest
You can either sneak up and take down the cult priest or engage him in combat to neutralize him.
Leave the Mystery House
The quest will complete as soon as you exit the Mystery House.
