What happened to Sanctuary?
The worst outcome: it lost. Blizzard's "Forging the Next Era" sums up the premise in one line: "the heroes of the past have failed, Sanctuary has fallen, and Diablo has won." Confirmed[B1] news.blizzard.com · verified Oct 10, 2026
Few humans have escaped Diablo's rule. Some bowed to him or joined his cults; a few were corrupted into Dread Commanders. Confirmed[B1] news.blizzard.com · verified Oct 10, 2026

Why the map changes when you return: see the Diablo 5 procedural world. Who sits on the throne: see Westmarch.
Where is Diablo 5 set?
On Sanctuary's Western Continent, which Blizzard places at the heart of Diablo's reign of terror. Confirmed[B1] news.blizzard.com · verified Oct 10, 2026
On stage, Joe Shely put it simply: the continent is "essentially greater Westmarch," and all of it has been devastated. Confirmed[T2] warcraft.blizzplanet.com · verified Oct 6, 2026
Blizzard hasn't named a single region, city or dungeon below the continent level yet. Confirmed[B1] news.blizzard.com · verified Oct 10, 2026
What was the golden age?
The peace that followed Diablo 4. At the panel, narrative director Jennifer Brandes Hepler said that after Mephisto's defeat, Sanctuary enjoyed a golden age when it was better off than ever. Confirmed[T2] warcraft.blizzplanet.com · verified Oct 6, 2026
Senior art director John Mueller added, in an interview with Korean press, that the peace happened because players saved the world at the end of Diablo 4, which makes Diablo 5's collapse hit harder. Inven Global published it translated from Korean, so the English wording is the outlet's. Interview[T3] invenglobal.com · verified Oct 10, 2026
How many years after Diablo 4 is it set?
About 100 years, according to two developer interviews; Blizzard hasn't published the number on its official channels. That's why Terror Codex labels it an interview, not a confirmed fact. Interview[T3]×2 windowscentral.com + invenglobal.com · verified Oct 10, 2026
| What was said | Who and where | Status |
|---|---|---|
| Diablo conquered Sanctuary seven years ago | Tiffany Wat, official panel | Confirmed[T2] warcraft.blizzplanet.com · verified Oct 6, 2026 |
| The art shows what happened "since the last 100 years, especially the last seven years" | John Mueller, official panel (doesn't fix the gap with Diablo 4) | Confirmed[T2] warcraft.blizzplanet.com · verified Oct 6, 2026 |
| "Diablo 5 takes place 100 years after Diablo 4" | Wat and Mueller to Windows Central; the outlet doesn't say which one | Interview[T3] windowscentral.com · verified Oct 10, 2026 |
| The game opens "7 years after he has taken over Westmarch" | Wat and Mueller to Windows Central | Interview[T3] windowscentral.com · verified Oct 10, 2026 |
| 100 years after Mephisto's defeat, plus a "Lost 7 Years" the story uncovers | John Mueller to Korean press (Inven Global translation) | Interview[T3] invenglobal.com · verified Oct 10, 2026 |
| Roughly 100 years after Mephisto's defeat (journalist's paraphrase) | Group interview published by PlayDay | Interview[T3] playday.one · verified Oct 6, 2026 |
| "A century" after Diablo 4, stated as fact with no source | Reveal-day press and GamesRadar+ | Rumor[T3]×2 notebookcheck.net + gamesradar.com · verified Oct 6, 2026 |
The pieces fit: a century since Mephisto fell, and at the end of it, seven years of Diablo's rule. What's missing is Blizzard writing it on its site, in a post or in the game.
Does Mephisto return?
No official source says so. At the panel, Mephisto only comes up as the enemy defeated in Diablo 4 and as an example of a villain with depth. Confirmed[T2] warcraft.blizzplanet.com · verified Oct 6, 2026
What role do the Heavens play?
An ambiguous one: they're Diablo's target and also a power that left Sanctuary on its own. To Diablo, Sanctuary is a stepping stone to invading the Heavens. Confirmed[B1] news.blizzard.com · verified Oct 10, 2026
| Fact | Status |
|---|---|
| Sanctuary suffers Diablo's aggression and the "almost equally damaging indifference of the Heavens" | Confirmed[T2] warcraft.blizzplanet.com · verified Oct 6, 2026 |
| You may find an ally among the angels and turn Hell's powers against itself | Confirmed[T2] warcraft.blizzplanet.com · verified Oct 6, 2026 |
| One scene shows angels crucified before the burning spires of Westmarch (Mueller, after the teaser) | Confirmed[T2] warcraft.blizzplanet.com · verified Oct 6, 2026 |
| The angels didn't hold up their end, and their inaction helped tip the balance (paraphrase) | Interview[T3] playday.one · verified Oct 6, 2026 |
Matt Zitterman framed it for Korean press: Sanctuary is always caught in the middle of the Eternal Conflict between Heaven and Hell, and this time the balance is broken from the start. That's Inven Global's translation. Interview[T3] invenglobal.com · verified Oct 10, 2026 → The Eternal Conflict in Diablo 5
What does Sanctuary look like?
In three layers, per the art team: ruins of what was lost, corruption of the present, and Hell breaking through. Confirmed[B1] news.blizzard.com · verified Oct 10, 2026[T2] warcraft.blizzplanet.com · verified Oct 10, 2026 → The three visual stories of the Diablo 5 world

What we don't know yet
As of October 10, 2026, Blizzard has not said:
- on an official channel, how many years separate Diablo 4 from Diablo 5;
- what happened during Diablo's seven years of rule (the game will tell it);
- which regions, cities or dungeons of the Western Continent you'll visit;
- who the ally among the angels is;
- how Diablo came back.
We'll cover Sanctuary's history in earlier games once we have an official Blizzard source, not from memory.
