Download the AeternisMU Launcher
One secure launcher is all you download. Install it once, then choose any server — 90x, 500x or 9999x — and the launcher downloads, verifies and auto-patches that client for you.
Install in 4 Steps
1
Download the Launcher
Grab the official AeternisMU launcher from the button or a mirror — it is the only file you need.
2
Run & Sign In
Open the launcher and log in. One account works across every realm.
3
Pick a Server
Choose a realm inside the launcher — 90x, 500x or 9999x — and it downloads & auto-patches that client.
4
Enter the Realm
Press play and forge your legend through ice and flame. No separate client downloads.
