"Ah, it's you." You are approached by a member of the Lodge whom you recognize: one of Carl Sanford's bodyguards from your previous meeting with the president. "I regret to inform you that Mr. Sanford and the other members of the Lodge are busy with an important task at the moment. I would suggest you come back at a later time." You tell the man that your task is important, and offer to help in return for a meeting with Mr. Sanford. He considers you for a moment, then nods. "All right. We are attempting to open a device which we believe will help us bind the revenant you encountered earlier. You'll want to speak with Nathan Wick if you want to help. You can find him in the library upstairs." You thank him and turn to leave, but he grabs your arm and stops you, adding one final warning: "You should know that we intend to open this device at any cost. If you cannot stomach the consequences, once again, I suggest you leave."

At first, your investigation yields few answers. There is indeed a meeting of some sort happening at the manor tonight, though you're not sure why. Finally, you catch a break. On a nearby table, a written summons explains the reason for tonight's gathering: "Our timetable has moved forward. We must complete the trap by midnight tonight. The device we found will aid us in binding the revenant, so it is imperative that we find a way to open it before the ceremony begins. We have no time to waste with prudence or cowardice. Report to Nathan Wick in the sanctum at once." You are left with more questions than answers.

Though the box itself seems to fight you at every turn, with all four key components in your possession, you finally manage to piece together how to open the contraption. First, you twist and contort the box's many mechanical devices until the image on its lid lines up perfectly with the diagram in your possession (N). Next, you chant the Latin incantation inscribed on the small wooden plaque you found (M). It takes a few tries to get it right, but eventually you hear a click as the surface of the wooden container shifts and changes. A round indentation has appeared on the side of the box, matching the size of your mysterious block onyx coin (O). As soon as you place the coin inside, another wooden panel opens on the other side, revealing a keyhole. Finally, you insert the key of bone (L) into the keyhole and turn it. The lid begins to open, and suddenly the entirety of the room is engulfed in a rush of air as all light, color, sound, and matter is sucked into the box.
