Astral Building
by KarmaManPy
Astral Building adds the Astral Building Nexus, a block that grants creative-flight building inside a protected zone for Fabric on 1.20.1.
What it does
The Nexus marks a localized zone in which a player can fly and build in creative style. A holographic world border shows exactly where the building limits sit, with custom glowing boundaries for the ceiling and floor. The border is drawn as a visible overlay that does not cause lag.
Astral Storage is required, and Fabric API is required as well, so both must be installed next to Astral Building. The mod runs on client and server, and its files target only 1.20.1 with 1.0.0 as the latest build. Astral Building is released under the CC0 1.0 Universal license and is not open source.
The mod is aimed at survival players who want to skip scaffolding and block-swapping chores, and at builders who work on large projects that phantoms would otherwise interrupt, since the protected zone keeps them away.

Protection from phantom attacks
