Galosphere
by Orcinus
Galosphere expands underground caves with new biomes, mobs, gems and structures, and is installed on both the client and the server.
What it does
Crystal canyons hold two new gems, allurite and lumiere, which form large crystal structures inside the biome. Sparkles move through the canyons and carry both gems on their backs. Lichen caves are covered in lichen moss and giant mushrooms, and small spectres drift peacefully through them. Pink salt caves are coated in pink, rose and pastel salt, where a mysterious ancient shrine can be found. Forgotten ruins are rare underground structures with suspicious blocks to brush, and moles living there offer side quests.
Galosphere is published for Fabric, Forge and NeoForge across seven release versions, 1.18.2 – 1.21.5, with the latest files for 1.20.1 and 1.21.1. A server running it needs every connecting player to have it too. The code is not open source; the mod is released under All rights reserved. Four catalog mods require it, including Galospheric Delight, Galosphere Trimming, Galosphere - Spelunkery Compat and Galosphere Muskets.
