About this Mod
This is a passion project I made that adds 27 new dimensions, several new ores, blocks, mobs and biomes. Before downloading, please not that this mod only works for 1.21.4 and will not work in any newer versions, yes it says it works from 1.21.4-1.21.8 but that is not true, I will make a version for 1.21.8 in the future tho.
To go to most of the dimensions, craft their portal igniters and go through concrete portals, there is a vast array of dimensions, some peaceful, some hostile, some are outright impossible to survive.
Just note this mod is no longer in active development, this isn't intentional, while making version 1.3.2 it just prevents you from loading into worlds and idk what I did or how to fix it, so I stopped updating because I don't wanna distribute a broken version of the mod. 1.3.1 will be the last version as of right now

Sapphire,
Rainbow,
Amber,
Amethystine,
