Sanctuary
Sanctuary is a Fabric world preset for Minecraft 1.21.11 that transforms the Overworld into a floating-island world centered around a handcrafted survival spawn zone.
Start in a curated central sanctuary, then travel outward into a vast procedural skyworld of islands, ruins, caves, and distant horizons.
Features
- Floating-island Overworld preset
- Handcrafted central survival zone near spawn
- Custom island generation with multiple landform presets
- Curated biome area around origin
- Procedural floating islands farther from spawn
- World creation customization screen
- Friendly with many biome-expansion mods
- Vanilla survival focused
World Design
Sanctuary blends three generation layers:
Custom Central Island Generator
Builds the main spawn landmass.Sanctuary Biome Zone
A controlled region near spawn for a stronger early-game experience.Fallback Overworld Biome Source
Expands naturally into broader procedural floating islands in the distance.
Safe start, dangerous horizon.
Customization
When creating a world, Sanctuary includes configurable settings such as:
Shared Settings
- Main Island Preset
- Starting Biome

- Surface biome packs
These biomes may appear:
