Marston's Fallen Stars
Marston's Fallen Stars adds procedurally generated meteor impact sites that appear naturally across Overworld biomes during world generation.
What it does
Meteors land in the Overworld as part of world generation, so each impact site is created when its chunk loads rather than placed by hand. Every site is built as a layered structure: a solid iron core at the center, a middle band where obsidian and iron are mixed, and an outer shell of basalt blended with obsidian. The inner 35 percent holds the core, the band from 35 to 60 percent holds the mixed layer, and the remaining 60 to 100 percent forms the shell.
The spacing between meteor attempts is set by two server-side options: a minimum number of chunks between spawn attempts, which defaults to a fixed value, and an additional random spacing on top of it, also at its default. Adjusting them changes how often impact sites appear. The mod is server-side only, so players join a server running it without installing anything. Its commands require operator level 2 permissions.
Marston's Fallen Stars is published for NeoForge only, across 11 release versions 1.21.1 – 1.21.11, under All rights reserved, so it is not open source. The latest NeoForge file is 1.0.0 for 1.21.11, released on 2026-01-24.
