I don't know my version or loader









Welcome to a world beyond our own with creatures and biomes that may seem familiar. Using powerful magic and overworld science, constructing a portal to traverse the multiverse is possible.
THIS IS A BRIEF OVERVIEW
PLEASE VISIT THE OFFICIAL WIKI
PLEASE NOTE THAT THE 1.19.2 AND 1.18.2 VERSIONS DO NOT HAVE MOST FEATURES LISTED IN THE WIKI.
HOW TO ENTER
OBSIDIAN B12
A chemical compound created using Obsidian and other crystalline materials.
RIFT TOTEM
A magical totem created in the image of a space-faring species. Can be used to ignite an Obsidian B12 frame to create a World Gate.
BIOMES
PLACID WOODS
A tranquil forest with tall colourful trees, shrubs, vibrant flowers and geodes with magnificent crystals.
SANGUINE GLADE
A conundrum of a forest: covered in scarlet moss, shrubs and pale fungus - yet dotted with dry stone spikes and cooling magma.
VOCAL SANDS
A barren landscape sparsely decorated by violet stalks, crystals, thorns and toxic growths. Suspended above the ground with odd magic, pieces of the land float in the air.
DEEP HORIZON
A mysterious zone where the physical and spiritual planes converge; archaic skeletons, marine flora, and ancient ruins dot the starry dunes.
LIVING CAVERNS
The caves that make up the Ulterlands underground, covered in jagged rocks that seem to grow before your very eyes and peculiar stone boulders.
EXTRAS
All of the above, 15 new mobs, a new crafting system, new weapons, an entire magic system (with 7 spells and 10+ magic items), a new armour tier, 6 new status effects, redstone components, building block sets, and much more await you.
I recommend using JEI for easy access to basic recipes.
