Special dimension properties[]

Precasia has no special properties.


Precasia's generation consists of flat areas and hilly areas. There are two types of stone in the dimension: precasian surface-rock and precasian lower-rock. Precasian Lower-Rock makes up a majority of the underground, while the precasian surface-rock generates solely in the top few layers leading up to the surface, similar to dirt in the Overworld. The topmost layer is mostly made of precasian grass.

Caves generate underground in the dimension, similarly to Overworld caves. Four different fossil ores can be found underground in veins. Lava lakes can be found underground about layer y = 10 and below. The very bottom layers of the world are made of dimensional fabric.

Precasia has a day-night cycle, complete with a sun and moon, as well as stars at night. Precasia also has clouds.
