This Minecraft mod allows you to prevent the world generator from generating new chunks past a defined limit.
You can set the limit by changing the gamerule `chunkGenerationLimit`.
This mod also adds an alternative ending. You can turn this off with `/gamerule truncatedAlternativeEnding false`.
Requires Fabric API!
