Hub 2: Constable's Gate

You begin on a high ledge looking down over several foes and the gate itself. But don't sit there idling at the scenery as there is another couple of ledge in sight with Chaos Serpents on. Note the crystal sitting on the closet ledge; the Heart of D'sparil, which is your primary objective this hub, though of course you have to complete the entire hub to get it.

Below are several Centaur that will be alerted as soon as you fire a weapon. There is also a single Slaugtaur among them that may take you be surprise if you choose to hang up on the ledge to pick the Centaur off.

Once the area is sufficiently clear jump down and go to the gate. Behind it is a few Slaugtaur. But the bigger threat here is the Heresiarch that appears as soon as you enter a little way in.

You can battle the Heresiarch or, given that you don't need to go back out, you can lure him outside the gate where he is unable to get back in if the door shut's.

Up in the room the Heresiarch emerged from is the first part of your first task this hub; collecting three Yorrick's skull artefact's. Behind the skull is also where you must place the Heart of D'sparil once you have it. There are two wooden doors leading off the grass area behind the gate. The one nearest the gate leads to a currently sealed off portal. So enter the other one. A pair of Ettin's will ambush you as you reach the door. Behind the door is a large room with a switch on the back of a raised platform. Pressing it will open several alcoves with more Ettin's inside. Several of the alcoves also contain switches. Press them all and the door to the next area will open at the far end of the room.

Cross the bridge watching for the Stalkers in the slime on either side and head up the front stairs and follow the passage around to find a valve (note the portal you can see through one of the windows). Turning it will open the Sewer gates at the far end of the slime on the right side of the bridge (pressing it again will close the gate, and again open it etc), which you must go through. There will be a narrow corridor to your right. Travel down it and through the door to a room of Afrit's. You can find a segment of your forth weapon at the back of this room.

Enter the only other door to find two more valves. One lowers the slime in front of you while the other reset's the sewer gate. Though don't worry about resetting the gate, as like the other gate switch, this one is also re-usable.

Go back outside to the slime and enter the newly revealed passage to be presented with three passageways, two of which are currently sealed. Travel up the open one to find a switch which opens the bars blocking one of the other two passages. Up this second passage is a switch that opens the door blocking the third passage. Go up the lift behind the third passage to be presented with a teleported and another portal just around the corner.

The portal will take you to where you will ultimately need to place the three Yorrick's Skull's; Hub 2: Locus Requiescat and also one of two key's you require to unseal the portal back at the gate; the Axe key.

Returning with the Axe Key
Your back, with the Axe key. Now go through the above mentioned teleported to be taken to the room containing the portal you could see through the window back at the start of the slime area. Enter it to enter the Hub 2: Market Place, where you can pick up another Yorricks Skull and also the second key you need to unblock the portal back at the gate; the Steel key.

Returning with the Steel Key
Head back to the gate and use both the Axe and Steel key's to unlock the portal to Hub 2: Ordeal. Here you can collect the final Yorick's Skull.

Returning with all three Yorick's Skull
At this point you should have all three skull's. Head to the Hub 2: Locus Requiescat to place them.

Returning with all the Castle Key
After returning here from the Hub 2: Locus Requiescat with the Castle key, head to Hub 2: Ordeal to use it.

Returning through the portal from Treasury
You'll appear in a new, but fortunately small area of the map. You can turn left to find a portal back to Hub 2: Treasury and also a door leading to a part of the level you've already been to.

But you want to take the lift directly in front of you which will take up to a small passage way which leads to the ledge with the Heart of D'sparil on it. Pick it up and return to the room the Heresiarch emerged from right back at the start of the hub and place it on the pedestal. A switch will be revealed that completes hub.
