Aethermoor
A free idle RPG in your browser.
Aethermoor is a free browser idle RPG with a story worth chasing: you are the Operator, and something happened to the mage who kept the realm last. Progress keeps ticking while you're away, cloud saves follow you across devices, and five optional standalone worlds — each with its own save and a unique mechanic — extend the loop. One-time purchases only, no subscriptions.
Plays itself while you're away
Offline progress keeps accruing when the tab is closed — up to 12 hours free, 16 with Operator Plus.
Spells, helpers, and a realm
Start in a sleepy workshop gathering gold, then learn spells, summon helpers, and push out into the realm.
A story that loops
Uncover what happened to the mage who kept the realm last — and why the world feels like it has seams.
Five bonus worlds
Optional store worlds, each standalone with its own save and a unique mechanic — tides, mining claims, power grids, divine favor, radiation.
