Expedition of the Guild dungeons number 11 in the world of Aetheron, and every one of them has its own first-clear achievement. The list grew over the run-up to launch: the first playtest in May 2026 had three dungeons, the demo build shipped five and took roughly five to six hours to clear, and the October 2026 update added two more.
Expedition of the Guild dungeons you can clear today
The current build has 11 regional dungeons, and they are:
- Windfiend Canyon
- Scorching Desert
- Stonefall Canyon
- Hidden Forest
- Hidden Swamp
- Royal City Guards
- Underground Ruins
- Temporal Rift
- Demon Realm Ruins
- Sky City Ruins
- Demon Realm Hunt
Hidden Forest and Hidden Swamp are the two the October 2026 update added, and each has its own guide here: the Hidden Forest guide covers where farming turns over, and the Hidden Swamp guide covers the boss at the end of that map.
The 11 regional dungeons in Aetheron
The world these maps sit in is called Aetheron, and the set is regional rather than a single ladder — Ruins, Canyon, Forest, Swamp, Desert, City, Rift, Realm and Hunt all sit inside it. That structure matters for planning: the maps are separate raid targets with separate first clears, not a numbered campaign path you grind in order.
Two areas sit outside this list. The endgame tower and the Black Market Arena were added as new map content in the same October 2026 update, and the tower is its own world with its own rules — the infinite magic tower guide covers what changes inside it. Every one of the eleven maps puts a boss with its own mechanic at the end, which is what the boss mechanics guide breaks down.
Every dungeon has a first-clear achievement
Each dungeon is tracked separately in the achievement list, one entry for the first time you clear it. That gives the whole set a visible shape: your list of achievements is a checklist of how much of Aetheron you have actually finished, and the ones still missing are the maps you have not pushed through.
The same achievement list tracks the other end of the loop — gear milestones, talent points spent, heroes recruited — so a first clear is only one of the counters moving.
How many dungeons the demo build had
The demo build shipped 5 dungeons and took roughly 5 to 6 hours to clear them, which is a useful sense of scale for a first run through the set. Before that, the May 2026 first playtest had only 3 dungeons, and the hero level cap at the time was 6.
That progression is the reason the current build feels larger than the demo did. The demo's five maps are still part of the eleven, and the two newest additions — Hidden Forest and Hidden Swamp — sit alongside them. The Hidden Forest guide covers the point in that list where the maps start giving you talent money instead of gear.
Once the maps are familiar, what changes a run is the fight inside them rather than the walk to them. The boss mechanics guide covers what every boss asks of a party, and the gear stats guide covers the numbers that decide whether you survive one.
