Hollowmarch
by ouheaddd
With Hollowmarch, explorers find handcrafted structures scattered across many biomes, each guarded by its own hostile mobs and loot.
What it does
Hollowmarch is an exploration-focused world generation mod for Forge and NeoForge. Its structures are placed by biome: a large mansion turns up in gloomy woodland regions, a desert monument hides among sand dunes, a cold shelter sits in snowy frozen biomes, and an overgrown monument lies buried in jungles. Coastal houses, ocean monuments, road-side monuments and tall stone formations fill in the remaining terrain.
The mod adds custom hostile mobs, unique items, custom enchantments and new paintings. Structure-based loot rewards players who search each site, and a desert market and a massive airship drifting above the world add encounters with traders, engineers and airborne danger. Terralith support is included for compatibility with biome mods.
Hollowmarch is available for Minecraft 1.20.1 on Forge and for 1.21.1 on NeoForge. Both builds are published at version 1.3.0, and the mod runs on client and server, so the server and every player need it. The code is released under the MIT License, but the mod is not open source.
