SlowMU Season 21

Type: MU Online Private Server
Website: slowmu.com
Tagline: O MU clássico, no ritmo certo (Classic MU at the right pace)

SlowMU is a Brazilian MU Online server running Season 21 Part 2.3 on the IGCN emulator with the official client. It is built around slow, permanent progression: there are no resets and no server wipes, so the level a character earns stays with it. The server opens on September 24, 2026 at 12:00 (GMT-3), with the game client released the day before at 18:00 (GMT-3).

The server runs the modern Season 21 content on IGCN files rather than a custom client.
