Arcpocalypse
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
The Arcpocalypse
have you ever wanted to become Neco Arc? This is your chance!
Craft two Abyss Lifts and make sure that they're next to each other and directly above the void. Place a cat in one, place yourself in another, and let yourself stare at the Void, and thus let the Void stare back.
