Cathedral Grounds

This is the Mechanist Cathedral. These people are not fond of magic, but they do have a penchant for big, heavey hammers. Sneakery is very helpful here. Look for gears. They are important to the Mechanists.

Front Courtyard When the guard has gone by, go to the door in front of you and go through into the church. Once inside, turn left and go through the door and up the stairs. You will see a room with bookshelves and a bench on the right. There is also a door on the right made of bars. Now turn left again and go up the second set of stairs. From here, there are stairs going forward, and stairs going to the left. Do not turn left up the last stairs. Continue straight along the walkway. You can see the front courtyard below to your right. At the end is a door. This room is the bell room, where you can ring the bell.
Bell Room Past this room is another walkway with the east courtyard to the right. At the far end, part of the railing is broken away. You can jump down onto the metal ductwork which leads to a balcony. The door in front of you leads to Gretus' chamber. Once you get the special loot from the chest, continue to the next room. Walk past the short hallway and through the columns, then through the archway. There is a room here with beds and a sleeping person. Get the loot from the chest without waking him, or not. Now go back out to the balcony. Don't forget the health potion on the shelf in the hallway before you leave.
Balcony Go down the stairs into the courtyard. Enter the door on your right. When you get into the church, you can go to the other side through the front, middle, or back, depending on where all the guards are. There is another archway on the other side that leads to the west courtyard.
West Courtyard There are two Hammerites talking here. When they've finished, you can go forward into the factory.
Factory Entrance On your right is a room with a guard. Go in just a little until you see a lever. Pull it and leave. That will activate the bellows interchange grill. It will also kill the guard on the right if you haven't already done so. Go straight ahead from the entrance into the room with the grating on the floor. Activate the switch there. You are supposed to use moss arrows on the floor and sneak up behind the hammerite that walks through, but you aren't going to do that. There's a much easier way. You will go right into the room with the two doors and wait in the darkness. Then whack him when he walks through. Then go back to the grating room and turn right past the switch. Go through the room with the stamping machine. Turn left into the charnel furnace room. There is a sick puppy there doing experiments on the dead. Put him out of our misery somehow. Be creative here. Don't forget to pick up the loot in the furnace chamber. Once you have done this, continue on to Inspector Drept's office.
Inspector Drept's Office Unlock the door to the office. There is a switch inside that you need to turn on. You probably want the loot since you went to all that trouble anyway. Go back out of the office. Make sure to read the note on the table. This will give you a valuable clue for finishing the level. Also, pull the lever on the wall. Then continue to the next room. There are stairs on your left. Make sure not to draw the attention of the man looking down from there. Turn right so that you face the storage area. There is a switch on your right on the transform regulator. Then go into the storage area. Grab the unstamped gear from the shelf on your right. Flip the switch in this room, then grab all the other loot. Now you must backtrack. Go back through the charnel furnace room to the stamping machine. Place the unstamped gear in and wait. Don't worry about it hurting you. Continue on to the grating room, then turn left. Keep going until you see a door marked "Reliquary."
Reliquary Here you see two machines. They both have a small round mechanism in the middle. Put the hammer in the first, and the stamped gear in the other. The cage will lower. Go up to the top floor to retrieve the chalice from the cage. Now return to the outside and you are done.
