Ghost Sky
by korosuke
Ghost Sky turns a new Minecraft world into a mostly empty SkyBlock island, with structures and their mob spawning kept in place.
What it does
When a player creates a world with the Ghost Sky world type, the overworld terrain and generated blocks are removed. Structure bounding boxes still exist, so structure-specific mob spawning keeps working: a swamp hut still attracts witches, and similar rules apply to Nether fortresses and ocean monuments. A key shows the bounds of structures in-game, which helps players build a platform inside the original area.
Because the terrain is gone, the mod supplies alternative ways to obtain items that normally come from generated blocks. A starting tree and a starting chest are provided, a minimal stronghold leads to the End portal and End cities, and lava can be produced from an oxidized copper pyramid struck repeatedly by lightning. Fabric API is required, and the mod is published for 26.2 only, with the 1.0.4 file released on 2026-09-07. Server owners install it, and players connect with no copy of their own.
Key features
Structure-aware SkyBlock
Structure bounds and their spawning rules stay active on an otherwise empty island, so mobs still appear where the vanilla rules place them.
Replacement progression
Items that depended on terrain get alternative sources, built from existing blocks, mobs and mechanics such as biomes and structures.
Nether and End generation
Nether and End content is generated in minimal form, giving access to the Nether, the End portal, End cities and elytra.
Presets and settings
The Customize screen offers three presets, plus individual settings for the generated content.
In-game guide
A guide opened with the U key explains each mechanic, and both English and Japanese text are supported.

What the author says
Ghost Sky is a Fabric mod for playing Minecraft as a mostly empty SkyBlock world. In the Overworld, normal terrain is removed and structures are not generated as blocks. Their locations and bounding boxes still exist, however, and structure-specific mob spawning still works.
