Note: The Black Soulstone quest doesn't start at the Hidden Camp like other quests in Act II. This quest commences when you have collected both Blood of Zoltun Kull -- completing the quest: Blood and Sand.
Use the Town Portal at the Vault of the Assassin. Then use the Waypoint at the Hidden Camp to teleport to the Desolate Sands (if you unlocked it earlier).
Search for the Archives of Zoltun Kulle at the northern end of the Desolate Sands
I doubt that Kulle's archives will be much more appealing than anything else I have seen thus far. This will be my chance to see how deeply disturbed he actually is underneath that sneer.
LOCATION: DESOLATE SANDS
Note: Take the Waypoint to Desolate Sands.
Note: Head west and go through the bridge to enter the Archives.
Zoltun Kulle: My archives are at the northern tip of the Desolate Sands. There we will find my body and the Black Soulstone. Here is the entrance to my archives. Let me activate the portal.
Note: Enter the Archives of Zoltun Kulle.
Go to the Terminus in the Archives of Zoltun Kulle
LOCATION: ARCHIVES OF ZOLTUN KULLE
Zoltun Kulle: I had to build all of this for my research and my experiments. The Black Soulstone was a complicated creation. I sacrificed much to make it.
Note: As you walk past the Archives of Zoltune Kulle Waypoint, Leah teleports in.
Leah: Looks like I got here just in time. Emperor Hakan? What are you doing here?
Emperor Hakan II: Good, everyone's together. I came to tell you that I have found Belial, and I'm ready to lead you to him.
Zoltun Kulle: All well and good, but first I will be made whole.
Leah: We're ready to do our part. Just you remember yours.
Zoltun Kulle: Beyond these portals lie two relics that were once powered by my blood. Take the vials you recovered and use htem to activate the relics.
Leah: I will stay here and prepare the ritual. Be careful!
Open the Shadow Locks in the Unknown Depths and the Storm Halls.
Unknown Depths Shadow Lock opened
Storm Halls Shadow Lock opened
The further we go, the more I'm convinced that this is a dangerous plan. Leah is uneasy as well. Should anything go wrong, I will be ready.
Note: Enter The Unknown Depths.
LOCATION: THE UNKNOWN DEPTHS
Zoltun Kulle: Angels are no better than demons. Did you know that they once voted on whether or not to eliminate all of mankind? Only one vote saved us from extinction.
Zoltun Kulle: Yes. Whatever else he may be, he is the Aspect of Justice... and there is no justice in murder.
Note: Explore The Unknown Depths until you find the Shadow Lock -- which is this giant orb in a circle.
Zoltun Kulle: I could have helped all men become nephalem and ushered in a golden age! But my Horadric brothers could not accept man's true destiny.
Note: Don't forget to pick the Hunter's Journal.
Note: Activate the Shadow Lock.
Note: Go to all the remaining 3 wings to search for the portal back to the Terminus.
LOCATION: THE TERMINUS
Note: At the Terminus, go through the bridge to the portal that takes you to The Storm Halls.
LOCATION: THE STORM HALLS
Zoltun Kulle: We all agree that the end times are upon us, but do you truly believe that Belial and Azmodan could have engineered these events?
Necromancer: For now, they are the greatest threat.
Note: Pick the Hunter's Journal near the Shadow Lock.
Note: Search the 3 wings around the Shadow Lock to find the portal back to The Terminus.
Enter the Realm of Shadow through the Terminus
Kulle's behavior is increasingly strange. If he doesn't contain himself soon, I may be forced to use his wretched body for skeleton parts once I retrieve it from the Realm of Shadow.
LOCATION: THE TERMINUS
Templar: This must be the shadow portal. Let us be done with this.
Find Zoltun Kulle's Body in the Realm of Shadow from the Terminus (0/1)
LOCATION: REALM OF SHADOW
Zoltun Kulle: The Horadrim did all this to lock my body away. They must have been very angry with me.
Necromancer: If they could not kill you, what else could they do?
Zoltun Kulle: They were never very imaginative.
Note: Search for Zoltun Kulle's Body and loot it.
Zoltun Kulle: You do not trust me. I understand. But we are more alike than you know. We have both tasted what it is to be nephalem. Join with me, and we can become the masters of this world.
Necromancer: You have misjudged me. Do not do it again.
Note: Pick the Hunter's Journal from the ground.
LOCATION: THE TERMINUS
Necromancer: I have the body.
Leah: Then let me begin the ritual... but I'm warning you, Kulle, you'd better not cross us!
Talk to Leah in the Terminus
I begin to see what has gone awry in Kulle's mind. He can see that the angels and demons are two sides of the same battle -- opposites in every way, but an equal threat to humanity. But he has no sense of the Balance, or his place in it.
Zoltun Kulle: You are surrounded by deceit, young one. I am the least of your concerns.
Zoltun Kulle: Concentrate, Leah!
Zoltun Kulle: Soon now. Just a bit longer. Just a moment... Almost... Yes! My blood... thunders within me! This fetid air fills my ravaged lungs... I am alive again!
Leah: You're welcome.
Necromancer: And the soulstone?
Zoltun Kulle: Very well. The bargain stands. Quickly, to my sanctum!
Enter the Soulstone Chamber through the Terminus
Kulle's body was never meant to be reformed. I do not know what spells Adria taught Leah, but her magic is foreign to me. Kulle himself has become bolder, as though he can no longer disguise his ambitions. For all his brilliance, he suffers from an overabundance of ambition.
Note: Click the Soulstone Chamber portal.
Talk to Zoltun Kulle
Zoltun Kulle: At long last, I can complete my life's work. All will tremble at my power!
Zoltun Kulle: What is this?
Zoltun Kulle: How has this happened? The souls of the dead Lords of Hell have been absorbed into the stone! Abandon your quest, nephalem. Your allies seek only to control you. With the power I offer, you and I could rule over all creation.
LOCATION: SOULSTONE CHAMBER
Necromancer: No. Give me the stone, or face me as your enemy.
Note: Kill Zoltun Kulle at max level in less than 30 seconds in Torment difficulty to get the Achievement: How Imaginative.
Get the Black Soulstone in the Soulstone Chamber through the portal from the Terminus
Kulle's betrayal was inevitable, but Adria's manipulation of the Black Soulstone came as a surprise for all of us. She'd better not be keeping other secrets.
Zoltun drops a journal.
Note: Before leaving the chamber, move to the center through the sandy bridge so that your hero is beneath the Black Soulstone. A cutscene is triggered. Adria takes the Black Soulstone.
Necromancer: Is it true, then? The slain Lords of Hell are within this stone?
Adria: Twenty years ago, during the Darkening of Tristram, Cain told me of Zoltun Kulle's profane soulstone.
Leah: That's why you left me... You went to mark the demons' souls, so that they could be drawn into Kulle's vessel!
Adria: Yes, my daughter. I have sacrificed everything for this...
Talk to Adria in the Hidden Camp
LOCATION: HIDDEN CAMP
Note: Use the town portal to leave the Soulstone Chamber and return to the Hidden Camp.
Necromancer: This soulstone is a weak vessel. It may not be able to contain Belial and Azmodan as well as the others.
Adria: Then I will shatter it, and the Lords of Hell... will be no more.
NEXT QUEST: THE SCOURING OF CALDEUM

Note: These dialogues are unlocked after completing The Black Soulstone quest.
