Mysterium is a mushroom cavern dimension.


Mysterium with Night Vision.


The Mysterium dimension can be accessed by using a Mysterium Realmstone.png Mysterium Realmstone on a portal structure. The Realmstone for Mysterium is obtained by killing a Creepird while the player is inflicted with Poison with a Blank Realmstone in the players' inventory.


Mysterium has no day/night cycle. A moon is present, and Clocks always stay at midnight. Respawn anchors still work normally, but maps only document the surface of this dimension.


Mysterium is a cave dimension, but unlike the mod's other cave dimensions, Mysterium has a surface instead of a dimensional fabric ceiling.

The surface of Mysterium.

The surface with Night Vision.

The surface of Mysterium is located at y=121 and above, and is mostly flat with only minor elevation changes. The surface is covered in rainbow grasses, and other mystic-themed foliage, as well as different colors of model shroom blocks. Distortion rune shrines generate floating above the surface, the only structure to do so. The surface is made of fungal grass, with a few layers of fungal dirt beneath it, which eventually leads to the fungal rock that makes up the underground.

Most of Mysterium's activity, generation, and structures takes place below the surface, deep underground in the dimension's many caves. The caves exist from the surface all the way down to the bottom of the world. While some of the caves are small, like overworld caves, others are larger and more expansive. The underground is mostly made of fungal rock, though the surface of the caves is made of fungal grass, with no fungal dirt.

The surface of the caves contains the model mushrooms (same ones as the surface), red/brown mushrooms plants, different colored glowshrooms, and large mushrooms similar to the large red ones found in the Mushroom Fields biome in vanilla Minecraft. These big mushrooms come in seven colors: five colors added by the mod (green, blue, yellow, orange, and purple), and two vanilla colors (red and brown). The brown mushroom blocks take the form of the big red mushroom in vanilla Minecraft, instead of the big brown mushrooms that vanilla normally has.

Towards the bottom of the world, water lakes can be found. Mystite ore generates in the underground. Dimensional fabric exists at the bottom of the world.
