In the author's words

A survival mod set in an endless blizzard. Warmth, light, and shelter actually matter. Farming still works, but different No tutorial — find your way by trial and error, and by reading what the survivors before you left behind.

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file hardcore-winter-1.5+26.3-fabric.jar. The scan reads the mod's classes; it does not run them.
