About this Modpack

This modpack centers around the unsettling horror of wonderland.jar — a mod that creeps into your world and won’t let go. In every shadow, something watches… and eventually, it steps through into your reality.

wonderland.jar introduces no_one, a mysterious entity that stalks players relentlessly and can pull you into “Wonderland” — an eerie network of liminal dimensions filled with endless corridors and impossible spaces.

Inside Wonderland, you will find:

11 surreal and unsettling levels
13 different entities, some passive… others actively hunting
Thick fog, distorted spaces, and a constant sense of dread

This modpack is built to deliver a slow, psychological horror experience. You are never truly alone. Even when nothing is there, it feels like something should be.

Explore carefully. Listen closely.

Wonderland is always watching.
