The Book of Lorath may have just teased where Diablo 4’s expansions could take place. By detailing a few events that take place after the Diablo 4 campaign, this lore book has given players some big hints as to where they might go next.
At the end of the Diablo 4 story, players are left on quite the cliffhanger. Neyrelle has absconded with the soulstone containing Mephisto’s essence, Lorath Nahr is the last Horadrim, and the Church of Light is hunting down the player and all of their allies.
Though the story in Diablo 4 itself is on pause until the expansion drops, the Book of Lorath, its companion lore book, goes on to explain what happens next. The tome was penned in-universe by Lorath Nahr himself, detailing the events that occurred before, during, and after Diablo 4. As Neyrelle travels Sanctuary, seeking a way to destroy Mephisto for good, Lorath is hot on her trail, discovering letters she left him along the way. Wowhead cataloged these letters for ease of viewing, and even made a map showing where their travels took them, with the soulstone representing Neyrelle and the Horadrim icon representing Lorath.
Neyrelle went to the following locations on her odyssey:
She visited Lorath’s cabin outside Kyovashad, leaving him the first letter.She passed through Yelesna, which fell to Hatred’s corruption from her presence.Neyrelle traveled across the Twin Seas from Kurast, but her presence in the city caused old hatreds from Mephisto’s ascension 70 years ago to flare up once more.Her trail goes cold at Ivgorod, the city where Diablo 3 Monks hail from, where she received training from the reluctant sages on how to stave off Mephisto’s corruption.
In his pursuit, Lorath’s journey took him to familiar locations like Westmarch, Tristram, and Lut Gholein, but he did not find evidence of Neyrelle in these places. He also went to new locations like the Skovos Isles and Xiansai, the homeland of Diablo 3’s Wizard class. Whether it be iconic locations like Tristram or new ones like Ivgorod or Xiansai, the Book of Lorath casts a wide net as to where players might go in Diablo 4’s in-development expansions.
Either way, the situation looks bleak. According to the Book of Lorath, the Cathedral of Light has also seized the Horadric Vault, and Neyrelle seems to be struggling to hold back Mephisto’s corruption. Only time will tell if players are able to help Neyrelle avoid the grim fate of becoming a vessel for the Lord of Hatred.
