The Beyond - Isleweaver Addon
by Nacolla
Isleweaver, an addon for The Beyond, adjusts how other End mods place their biomes, structures and decorations so they sit on Beyond's terrain.
What it does
Many End mods register biomes in the standard way through shared End biome tags, and the addon folds those biomes into Beyond's End automatically. Structures and plants then follow Beyond's real islands instead of hovering over flat void, and decorations that once filled the deep End below y=0 no longer go missing. Isleweaver steps aside for the exit portal, the altar and the dragon's den, so those build cleanly where they belong.
Biomes generate alongside Beyond's own, keeping their distinctive looks and surface styling. Larger mods that need extra attention receive hand-written handling so they fit Beyond's islands, and a handful of others are fixed so they wake up when only this mod is installed. Isleweaver requires The Beyond and works whenever Beyond owns the End. It runs on NeoForge and is released under the MIT License, so the source code is open.
Key features
Automatic biome folding
Biomes from compatible End mods are picked up from the shared End biome tags and placed inside Beyond's End.
Terrain-aware structures
Structures and plants settle onto Beyond's islands and ground instead of floating over empty space.
Filled deep End
Decorations that previously appeared below y=0 are placed back in the End, so they no longer vanish.
Hand-tuned large mods
Bigger End mods have individual adjustments so their islands and features fit Beyond's terrain.

What the author says
Most mods just work, no setup. Any End mod that registers its biomes the standard way, the shared End biome tags that Fabric and NeoForge mods already follow, is discovered automatically and folded into Beyond's End. No config, no per-mod tinkering. The biomes generate right alongside Beyond's own and keep their…
