You now have the Machine Room Key, so what’s left is to find the Elevator Parts in order to go deeper into Brennenburg Castle’s Inner Sanctum, where Alexander is. However, this will definitely not be as easy as getting the key was. There are a lot of things you need to do before you can get to them, and it may get a bit frustrating.
As you leave the Guest Room after getting the MACHINE ROOM KEY, you’ll find a dismembered torso in front. The monster that you hid from earlier in must have been feasting on it before it started to look for you. With that out of the way, it’s time to move on to the next room on the left, which is the Study.
Go straight and there’ll be an open room to the right. Once you’re inside, there’ll be a TINDERBOX on the shelf to your left, and another in a chest near the window. Go the the next room at the front and you’ll see a note on a table near the window. It’s from a certain Agrippa, a teacher who says that he stole an orb and was chased around by some monster. While trying to escape, he got teleported miles away from where he was. Whatever was chasing him seems to have caught him and taken back the orb.
Go back to the hallway and make your way down until you find an area with lots of windows. It seems that the first window is a bit weak, and there’s a bottle of OIL there. Leave that for later and enter the room on the right. It looks like a really weird slaughterhouse where animals were killed. Head for the table to the right and watch the flashback.
You’ll hear Alexander cutting up animals, which is pretty sick. Around the table in the middle of the room, you’ll see a note near the candle and the decapitated dog’s head. The note explains why Alexander was going psycho on the poor animals was because he was harvesting something from the brains of humans and animals. To produce this something, fear and pain must be induced upon the victims for “harvest”.
There’s another note on the table in the next room. This time, Alexander was frustrated about not being able to get what he needs due to lack of previous data. After that, search the drawers for a TINDERBOX and a cute surprise. Exit the room and walk back into the hall. There’ll find that the boulders are blocking your path. There seems to be no way out at this point, but remember that there’s a weak window from earlier.
Once you’re in front of that window again, click on it repeatedly until it breaks. You can also throw something at it to break it, like a decapitated dog’s head. Either way, you can make your way through it with no problems. Just make sure to grab the bottle of OIL there before you go through. Land on the perch, where you’ll find a TINDERBOX. Jump from perch to perch to another open window.
Inside, you’ll find a glowing canister, which you must read. Whoever wrote it expresses disappointment at Agrippa, the teacher who earlier stole an orb. The author speaks of having lived for centuries and having done so much for Agrippa, only to steal the orb and enter the gate instead of him. The plot thickens.
The next room has an oil barrel for replenishing your lantern. There’s a table with a rod and a note that talks about a certain setting to make the Elevator work — 8 up and 8 down. Three rods are needed to make it work, and the one on the table seems to be the Flow Cycle Rod. The next room has a chest on the left corner near the painting with two TINDERBOXES. There’ll be nothing left for you in the Study, so head back to the Back Hall through the window and proceed to find the rods.
After getting out of the Study, go right and make your way down the stairs. At the fountain, you’ll get a flashback of Daniel being embarrassed about being forced to use a parasol. On the right from the fountain, there’s a door that leads to the Storage room.
Down the stairs, there is an open area where Daniel will start writing in his journal about the Storage being so dark that it can’t be natural. Of course, you’ll need to light some torches. There should be a table in front of you, a hallway behind that, a door to your left, and another hallway to the right. Get the TINDERBOX on the table and proceed to the left. There’s a TINDERBOX on the shelf to the right side of the room. There are two more on the middle shelf by the left side. The shelf in the corner has a Drill Part. As you take it, you’ll hear a monster outside. Danger is coming, but you should be safe for now.
Get out of there and and walk into the hall directly in front of you, not the one to the left. As you reach the bottom of the stairs, turn right. Enter the door into a room. There is yet another table with a note and a TINDERBOX at the bottom. The note tells about Agrippa, who turns out to be Alexander’s teacher, having prepared an explosive. The required chemicals are in two large vats outside that room. The chemicals are said to be unstable, so you must handle them with care.
Exit the room and keep moving while hugging the right wall until you reach the next room with a slightly open door. The shelf on the left has a TINDERBOX, and the shelf on the other side has another TINDERBOX. There is a chest by the corner containing another TINDERBOX, a bottle of OIL, and some LAUDANUM.
Keep hugging the right side upon exiting the room and you’ll find another door. There’s a TINDERBOX on top of the box to the right, and another TINDERBOX in front of you. Behind that is another DRILL PART. Get out of that room and keep hugging the right wall to the next door. The shelf on the right inside that room has two TINDERBOXES. While the first tinderbox is within reach, the second one is high on top of the shelf. You can jump on the nearby table and jump towards that tinderbox, grabbing it as soon as you can. The other shelf and has another DRILL PART, which is the last one. Open your inventory to combine all drill parts by dragging one on top of another. Once combined, you have a HAND DRILL.
There should be a giant vat labeled “Primary” to your right outside the room. Open your inventory and use the HAND DRILL on the vat to make it leak. Open your inventory again to use the CHEMISTRY POT to get some of that chemical. Take the PARTIALLY FILLED POT and proceed to obtain the next chemical from the other vat.
Turn around and go for the other vat labeled “Secondary” right ahead. Repeat what you did with the “Primary” and that chemical will combine with what you already have in the pot. Congratulations, you’ve just made an EXPLOSIVE. You’ll hear another mad growl from the creature over yonder, but don’t fret just yet. Go back to where you came from upstairs and continue to explore the area.
From the top of those stairs, go straight down the hall to the right, which is the last unvisited part of this area. You’ll see a flashback of a woman crying and just wants to be left alone upon entering. There’ll be a room to your right that can’t opened, so ignore that for now. Go downstairs and get the TINDERBOX on the ground near the candle.
As you get back to those nasty boulders blocking the way, open your inventory and select your EXPLOSIVE. Use it on the boulders to blow them into smithereens by grabbing a box, backing up a good distance, then throwing it straight at the explosive on the bottom of the rocks. It will go kaboom and the path will be cleared.
As you go on into the next area, there’ll be a shelf in the room in front of you with a TINDERBOX. To the left near a doorway are barrels by a corner hiding a chest behind them with two TINDERBOXES and a LAUDANUM.
In the next area, you’ll have another flashback where the girl is being harassed. Head on forward and you’ll find yourself in a long room with a slightly open door to there right. Inside, it’s full of dead pigs, which is quite creepy indeed. There’s a shelf to the right with a TINDERBOX. Move the barrels off the corner to find a bottle of OIL, then exit the room. Go right and move on until you get to a shelf on the right that has a TINDERBOX, then move on. Once you see another room to your right, get ready and stick this information into your brain — DO NOT OPEN THAT DOOR BECAUSE THERE IS A MONSTER IN THERE. DO NOT OPEN IT.
Just keep moving forward, leading towards the Machine Parts area. You don’t need to go there yet as there is still stuff to hoard. Check the crates on the right side around the table for a bottle of OIL. The long table nearby will also have another TINDERBOX. As you move forward from there, check the right side for one more TINDERBOX. You’ve obtained all items in this area, so proceed to the Machine Parts area.
Turn around towards the Machine Parts hall and get yet another flashback of the girl, who is now being cut and tortured. Move on to reach another area that will suddenly shake and cause a fire in the middle of that room. Don’t worry about right now and just enter the room to your right. The last two Elevator Rods are on the shelf, which is quite fortuitous. You’ll also find a note that talks about the first Rod you got from the Study earlier. These last two rods are the Trinity Steam and the Four Phase Amplitude Rods, which sound like superhero weapons.
As you pick them up, a monster starts going berserk. Move on out and turn right, where there’s a TINDERBOX behind a box. Since you now have all ELEVATOR RODS, you’ll have to make your way back to the Back Hall while keeping that monster off your tail. Remember that once you see even a sign of that monster, you’ll have to run back to the room where you got the last two rods and hide until its gone. You’ll have to turn off your lantern and slowly move from one point to another.
If you see it at this point, run to the Machine Parts room and hide. After a couple of minutes, slowly open the door and check if it’s safe to venture out. If it gets a good look at you, it may even break the door down to get you. Just stay in the shadows and hide in the corner to keep from being seen.
As you start making your way out, the door that you weren’t supposed to open as it had a monster inside is now open for obvious reasons. Go inside and take the TINDERBOX off the shelf, then climb onto something to get another one on the top. There is also another one lying on some sacks nearby. Turn your lantern off and exit that room. You’ll have to move from room to room, avoiding the monster’s attention. Slowly head up as you pass, right until you get to the pig room, which is quite close to where you must go to reach the Back Hall.
Once you think that the monster is gone, make a run for it and don’t look back. The path towards the Back Hall is up ahead behind the table. Get out of there as quickly as you can. JUST RUN.
