Hypothermos
by aseedadad
Hypothermos is a Fabric mod that makes the world cold and rainy, so players need fire to stay warm and safe.
What it does
The mod changes the weather and temperature of the world so it turns cold and rainy. Rain puts out a fire that is not sheltered, so a campfire-style shelter is needed. Lighting a fire requires a firestarter, flint and steel, and the light it gives keeps the surroundings warm. Hypothermos is client and server, so the server and every player need it. It is open source under the MIT License and is published for Fabric, for 1.21.11 only, with version 1.1 as the latest file.

Fire lighting

A fire is built by placing an oak log on the bottom and two cobblestone blocks on top, then lighting it.
