Hub 2: Locus Requiescat

Retrieving the Axe key
Your first visit to this Graveyard map is literally a flash. The Axe key is right in front of you. Just walk around the side of the bars to get it.

To exit the map turnaround from where you start to find two small passage ways with lift's that lead up to a room with a ledge that overlooks the graveyard below. On said ledge is a switch. Pressing it will lower the wall at the back of the room behind you. Behind which is the portal back to Hub 2: Constable's Gate (map).

Retrieving the Castle key
You should now have all three Yorrick Skulls. The Locus Requiescat is split into four segments, the one where you start and three others. At the entrance to each segment is a headless statue of Yorrick. Placing one of your skulls on a statue will remove the tree's blocking access to the area behind the statue. In each of these areas is a switch, all three of which must be pressed to access the Castle Key.

West statue
Having placed a skull on this statue and dealt with the Reiver's that emerge, enter the only accessible exit down hole and along the narrow passage to come to a wider corridor with a sealed door at the end and several doors down the sides, behind each lurks a Chaos Serpent. Slaying five of these will open said sealed door revealing a room a switch. This switch will raise a step back outside allowing you to reach the other exit off this segment. It will also open the walls either side of you revealing an Afrit and the entrance to the spiders tomb (pick up the shield) if you wish to try to get some goodies.

Head back outside and climb the steps up to the other exit off this segment to a room containing the required switch to complete this segment and also a pair of teleporters that take you to the ledges you could see behind the Chaos Serpent room's and a couple of small goodies.

North statue
There is only a single passageway leading off this part of the graveyard accessed after placing a skull on the statue. Down the end of this corridor is a switch that opens several walls back around the corner revealing pen's containing Dark Bishops. The back wall of one of these pens’s is fake (the angled one) and leads to another room containing more bishops and the segments switch. Pressing it will open several more Bishop containing pen's around you.

East statue
The right exit from this segment leads to a large amount of combined mana that you can get if you follow the rule. However break the rule and it's game over.

The left exit is where you need to go here. After dealing with all the Afrit lurking inside, notice the large number of destroyable corpses (some of which are up in alcoves behind the statues) and also the destroyable tree.

Destroying the tree opens a wall behind you leading up to the small windowed room containing a couple of Bishops who had been trying to attack you through a window that was too small for them to fire through, along with a Krater of Might.

Destroying all the corpses opens a smaller wall near it containing the segments required switch.

Getting the Castle key
Having pressed all three switches, the edge of the large tower in the centre of the map lowers allowing access to its interior. Dead centre of it sit's the Castle key on a raised pedestal. Picking it up will trap you briefly as several unavoidable darts and fireballs are launched at you from wall mounted launchers. After which you are free to escape.

You are now done with this map. Return to the Hub 2: Constable's Gate (map).

Trivia
Many of the gravestones on this map when pressed will display messages from HeXen's level designers.
