One Void
by cyanmayn
With One Void, a player starts from a single block in an empty world and builds up from it through a configurable challenge.
What it does
One Void is a world generation mod in which the world type named One Void is selected from the World section of the create-world screen. Choosing it and then clicking customize opens the settings, and the challenge begins with crafting from one block. Its settings cover the experience rate, the spawn block, loot and mob waves for each dimension, and modded dimensions are supported as well.
The mod includes a modular system for customizing ages, aimed at technical users, and presets can be saved, loaded and shared as a code. Loot chests can be set to give their contents once or to refill repeatedly, and mob waves are configured for each dimension. One Void requires Architectury API, and it runs on client and server, so the server and every player need it. It is published for Fabric and NeoForge, with files for 1.21.1 only, under the MIT License, and it is not open source.

Per-dimension setup
