About this project
What does Ninjacat Skies Core add?
Ninjacat Skies Core
The companion mods of the Ninjacat Skies skyblock modpack, packaged as one download so the pack can install them straight from CurseForge.
What's inside
Five mods, loaded through NeoForge's Jar-in-Jar system. Each keeps its own mod id, so existing worlds are unaffected.
- Ninjacat Lib – shared utilities for the other four.
- Ninjacat Skies – the Codex guide book, Skybound starter kits and the Strand story hooks that drive the pack's questline.
- Voidloom – void yarn, spindle tools and Loomframe sieving.
- Clowder Hall – the hub ceremony, island charters and the Clowder multiplayer layer, which keeps skyblock island teams and FTB parties in sync.
- Snapped Guardians – thirteen bosses summoned with Frayed Totems and fought in their own arenas. Each one drops a unique Woven Relic.
Requirements
- Minecraft 1.21.1 with NeoForge 21.1 or newer.
- No other required mods. Optional integrations: FTB Quests, FTB Teams, Skyblock Builder, Ex Deorum, Productive Bees, Curios and Modonomicon.
Made for the pack
These mods are built around the Ninjacat Skies quests, recipes and configs. They load on their own, but the intended way to play them is the modpack.

The Nethermaw
The Nether has oceans of fire that few things dare cross. Yet something more ancient than the fortresses tears through the lava: a colossal basalt leviathan. Ride its back from shore to shore, but when its spines start to smoke, get off before it dives.
