This quest involves the treachery of the former Archbishop. It is initiated by Deckard Cain after the Staff of Lazarus is retrieved from level fifteen. He will reveal that Archbishop Lazarus has turned to evil. A "red town portal" will now open next to the pentagram on level fifteen. This leads to the Unholy Altar. Inside, there are two Books of Vileness on stands adjacent to circles on the floor. Reading each one will teleport the hero into a room with several Hellspawn, a type of Succubus demon. After both Books of Vileness have been read, a new circle will appear where the hero entered the Unholy Altar. Using this will teleport the hero to Lazarus immediately following a cutscene. Lazarus will declare that the hero is too late and will set off a trap, causing several more Hellspawn and an Advocate to enter the room. Lazarus also has two Succubus bodyguards: Red Vex and Blackjade. The fallen clergyman himself is similar to an Advocate, but more powerful. Defeating him completes the quest, allowing access to level sixteen, and the final quest.
The cutscene shows Tristram's Zakarum Cathedral with mountains in the background and the shores of a lake to the left. Inside we see a church office, and Archbishop Lazarus looks human at first, but as the footage starts to show him up close, his eyes give off a bloodied glow.
Sometimes, even after you defeat Lazarus, a spell bolt that was still en route to you when you strike him down will hit and kill you. Even after you keel over and die, once Lazarus dies at about the same time, you will still utter, "Your madness ends here, betrayer!" in a tone sounding as if you were still very much in full health.
This is one of the four Diablo Quests that appears in Multiplayer mode. Instead of having to retrieve the Staff of Lazarus, the quest is initiated by Deckard Cain anytime after first reaching level fourteen. Lazarus is on level fifteen itself. He is in a room with the Unholy Altar (the altar itself with the sacrificed child, not the mini-level) and several other enemies (Succubi and Mages). Like in single player, Red Vex and Blackjade are guarding him, but this time, due to his small group always having a couple Hell Spawns, he will also have Bloodlust lurking somewhere on the level. Defeating Lazarus allows the player to continue to level sixteen.
Quest Activation Dialog
Deckard Cain: "This does not bode well, for it confirms my darkest fears. While I did not allow myself to believe the Ancient Legends, I cannot deny them now. Perhaps the time has come to reveal who I am.
My true name is Deckard Cain the Elder, and I am the last descendant of an Ancient Brotherhood that was dedicated to safeguarding the secrets of a timeless Evil. An Evil that quite obviously has now been released. The Archbishop Lazarus, once King Leoric's most trusted advisor, led a party of simple townsfolk into the Labyrinth to find the King's missing son, Albrecht. Quite some time passed before they returned, and only a few of them escaped with their lives. Curse me for a fool! I should have suspected his veiled treachery then. It must have been Lazarus himself who kidnapped Albrecht and has since hidden him within the Labyrinth. I do not understand why the Archbishop turned to the Darkness, or what his interest is in the child. Unless he means to sacrifice him to his Dark Masters! That must be what he has planned! The survivors of his 'rescue party' say that Lazarus was last seen running into the deepest bowels of the Labyrinth. You must hurry and save the Prince from the Sacrificial Blade of this demented fiend!"
NPC Quest Dialog
Adria: "I did not know this Lazarus of whom you speak, but I do sense a great conflict within his being. He poses a great danger, and will stop at nothing to serve the Powers of Darkness which have claimed him as theirs."
Farnham: "They stab, then bite, then they're all around you. Liar! Liar! They're all dead! Dead! Do you hear me? They just keep falling and falling... their blood spilling out all over the floor... All his fault..."
Gillian: "I remember Lazarus as being a very kind and giving man. He spoke at my mother's funeral, and was supportive of my grandmother and myself in a very troubled time. I pray every night that somehow, he is still alive and safe."
Griswold: "I was there when Lazarus led us into the Labyrinth. He spoke of holy retribution, but when we started fighting those Hellspawn, he did not so much as lift his mace against them. He just ran deeper into the dim, endless chambers that were filled with the Servants of Darkness!"
Ogden: "Lazarus was the Archbishop who led many of the townspeople into the Labyrinth. I lost many good friends that day, and Lazarus never returned. I suppose he was killed along with most of the others. If you would do me a favor, Good Master, please do not talk to Farnham about that day."
Pepin: "I was shocked when I heard of what the townspeople were planning to do that night. I thought that of all people, Lazarus would have had more sense than that. He was an Archbishop, and always seemed to care so much for the townsfolk of Tristram. So many were injured, I could not save them all..."
Wirt: "Yes, the righteous Lazarus, who was sooo effective against those monsters down there. Didn't help save my leg, did it? Look, I'll give you a free piece of advice. Ask Farnham, he was there."
Player: "Your madness ends here, betrayer!"
