Zereth Mortis campaign

The Zereth Mortis campaign covers the storylines added in patch 9.2 as the concluding portion of the overarching Shadowlands campaign, tracked in the achievements Secrets of the First Ones and From A to Zereth. The quests take place almost exclusively in the new zone of Zereth Mortis.

To unlock this campaign, characters must have finished the first three chapters of the Chains of Domination campaign, ending with Good News, Everyone!. Once that is done, Call of the Primus will be offered automatically as soon as players log in after patch 9.2 goes live.

The main campaign chapters were initially time-gated after the release of the patch, with chapters 1-3 being available at launch and with one additional chapter unlocking each subsequent week. Since then, all of the chapters can be played through from start to finish without interruptions or additional requirements.

The primary campaign is eight chapters long and covers the heroes' arrival to Zereth Mortis, their search for a way to follow the Jailer into the Sepulcher of the First Ones and defeat him, the creation of a new Arbiter to restore balance to the realms of Death as a whole, and finally the ultimate fate of Sylvanas Windrunner.

The Primus summons the Maw Walker to Oribos, where the attendants create a new sigil of the Arbiter and open a portal to Zereth Mortis to pursue the Jailer. Pelagos of the kyrian volunteers to accompany the Maw Walker. However, a Mawsworn attack disables the portal and leaves the Maw Walker and Pelagos stranded in Zereth Mortis. In exchange for helping him obtain a strange automa core, the broker Firim leads the two to the Enlightened in Haven. After the Maw Walker earns the brokers' trust by defending them from the Mawsworn, Elder Ara helps open an Ancient Waystone, establishing a permanent connection between Zereth Mortis and Oribos and allowing the Maw Walker's allies to join them.

Bolvar sends the Maw Walker, Shandris Feathermoon, and Darion Mograine to find out what the Mawsworn are up to near the Forge of Afterlives. They discover that the Jailer is converting automa with Domination magic to weaken the Forge's defenses and that the covenant forces have been infiltrated by nathrezim. In a duel with Mal'Ganis, Jaina, Baine, and the Maw Walker learn that the Jailer and Anduin are headed for the Forge. They arrive too late to stop the Jailer from using the Forge to enter the Sepulcher of the First Ones, taking Anduin with him.

Pelagos and the Maw Walker head to the Genesis Fields to deal with the other major threat to Zereth Mortis, the devourers. They hear an automa oracle's call for help, but they arrive too late and she falls unconscious. The Enlightened refuse to help, so Pelagos and the Maw Walker bring the oracle to Firim in Exile's Hollow. The automa core from earlier reacts to the oracle and turns into Pocopoc, a tiny automa who bonds with the Maw Walker, granting them the Summon Pocopoc ability and access to the Cypher of the First Ones. In addition, completing this chapter gives players access to Zereth Mortis' world quests and daily quests.

Uther shows up in Haven with the news that Sylvanas has awakened back in Oribos. Bolvar is more concerned with finding a way into the Sepulcher. Elder Ara lends her help by taking the Maw Walker on a pilgrimage: first to Provis Esper to find some First One artifacts, then to Pilgrim's Grace to learn more about them, the Catalyst Gardens to repair them (and deal with haywire automa), and finally back to Pilgrim's Grace to use them to activate the Ancient Translocator between the Sepulcher and the mainland, giving players access to the physical raid entrance. Uther convinces the others to accept Sylvanas' help in saving Anduin from the Jailer, and they head into the Sepulcher to do so.

This chapter takes place after the first eight boss encounters of the Sepulcher, but does not require any raid progress to access.

The heroes bring Anduin to Haven in the hopes that he knows how to counter the Jailer's Domination magic, but he has no answers to give. The automa seem to be more resistant to Domination, however, so the Maw Walker is sent to experiment with the Helm of Domination and finds out that the automa's resistance stems from the language of the First Ones. The Maw Walker, Bolvar, and Taelia head to the Endless Sands to collect First One phrases, after which those who've suffered from Domination in the past meet up in Bastion to uncover their memories of what helped them defy it. The Primus gathers the group in the Runecarver's Oubliette and uses the cyphers and memories to reforge the helm into the Crown of Wills, giving the Maw Walker and their allies a way to resist the Jailer's power.

Pelagos comes to Haven to report that something is happening with the oracle—Saezurah—in Exile's Hollow. Saezurah speaks through Pocopoc and guides the Maw Walker on a lengthy trip to the top of the Resonant Peaks to retrieve the empty Vessel of an Eternal One. Back in Exile's Hollow, Saezurah awakens and reveals that—once her preparations are complete—the Vessel will be used to create a new Arbiter to replace the one that the Jailer destroyed.

The Maw Walker is summoned to Exile's Hollow: it's time to make a new Arbiter, using a soul in the Crypts of the Eternal. The Crypts are guarded by Mawsworn, so the Maw Walker and Pelagos put together an army of covenant forces to get inside. The ritual begins, but a nathrezim ruins everything by summoning the Echo of Argus. All seems lost until Pelagos decides to offer his own soul as a replacement, and Saezurah transforms him into the new Arbiter. He takes his place in Oribos to allow souls to once again be sent to their rightful afterlives, and only one task is left before balance is restored to the Shadowlands: defeating the Jailer in the Sepulcher.

The final chapter is optional in that it is not required to earn Secrets of the First Ones. It takes place after the events of the last three boss encounters of the Sepulcher, but as with the "Crown of Wills" chapter, no raid progress is required.

Following the defeat of the Jailer and the saving of the Shadowlands, Sylvanas is escorted to Oribos to be judged by the Arbiter for her past crimes. She hands herself over to her archenemy Tyrande Whisperwind, who declares that she'll begin her penance by freeing all of the souls trapped in the Maw and sending them to Pelagos for judgment. Sylvanas accepts this and disappears into the Maw to get to work, closing off this last part of the Shadowlands storyline.
