Astrological (End Terrain & Biomes)
by Apothicon
Astrological reshapes the End dimension with new terrain generation blocks, stacked island layers beneath the vanilla ground, and a reworked end biome.
What it does
Terrain in the End is changed by new generation blocks, and two new island layers are generated beneath the existing ground. The end biome receives its own features, and custom End-themed lighting makes the dimension look different from vanilla. Players who enter the outer islands find a way toward the center island, where the dragon is defeated before they leave.
An anti-eclipse event pulls players who are in line of sight upward, lifting them telekinetically through the ambient light of the End. The mod adds more than 50 new blocks for building and decorating within this dimension, and the textures used across the mod are credited to Jacqueline Vile. Astrological was also used in modpacks.
Installation needs Forge or NeoForge for the matching release version. Both sides must run the mod, so a server without it cannot be joined by players who have it, and the other way round. Files cover 1.18.2, 1.20.1 and 1.21.1, and the code is released under the MIT License, so it is open source.

How it compares
Biome2 is server-side only and released under the Apache License 2.0, with files for 1.20.1 – 1.21.4, so it changes biomes without requiring players to install anything. Diabolical Islands is licensed under the MIT License and needs the server, with clients optional, for 1.20 – 1.21.11. YUNG's Better End Island is server-side only, covered by the GNU Lesser General Public License v3.0 only, and published for 1.18.2 – 26.1.2, so it covers the End without needing a client install.
