Cosmos

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): Cosmos did not start: java.lang.NoSuchMethodError: 'net.fabricmc.api.EnvType net.fabricmc.loader.api.FabricLoader.getEnvironmentType()'.

In the author's words

A highly configurable mod for better stars and night sky!
