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

There are several new ores:
Ruby,
Sapphire,
Rainbow,
Amber,
Amethystine,
Cobalt,
Abyssal,
Platinum,
Corundum,
Crystalline,
Aurorite,
Citrine,
Tennessine,
Abellyte,
and Almadine.

New Biomes:
Sapphire Forest,
Gray Forest,
Ruby Forest(in the nether),
Money Biome,
and The Diamond Biome

New Mobs:
Railer,
Slammer,
Slapper,
Guarder,
Cobalt Cube,
The Watcher,
Amethystine Phantom,
The Shadow,
Neon Walker,
End Walker,
Resin Hunter,
Amber Lord,
Flame Lord,
Rainbow Worm and Rainbow Creeper.

I recommend everything else you find out yourself but Watch my youtube video on this mod to understand it a bit more and to see whats coming next
