Impover Mod
by cantespeak
Impover gives server owners control over world generation, mob spawning, weather, day length and biome boundaries on Fabric 1.21.11.
What it does
Impover is a management mod that lets a server operator reshape the world beyond Minecraft's default settings. Specific creatures can be fully disabled or re-enabled, a choice of mobs can be set when a world is generated, and spawn counts can be changed afterward with commands that run while the server stays up. Weather, day length, the density of structures such as villages and dungeons, and the boundaries between biomes can all be changed as well.
The mod is open source under the GNU General Public License v3.0 only, and its source code is public. It requires Fabric and runs on the server, so only the server needs it: players can join without installing anything, though the client may carry it as an optional addition. Files are published for Fabric on 1.21.11 only, with version 1.0.0 as the latest file, on the beta channel. Some features are still marked unstable, and the author asks for feedback on the GitHub repository.
Key features
Mob spawn control
Specific creatures can be fully disabled, and the spawning of chosen mobs can be toggled without touching other populations.
Population commands
Mob populations are regulated through in-game commands, so changes take effect on a running server.
World setup
Weather, day length and the mobs present when a new world is created can be set before play begins.
Structure and biome tuning
The density of villages, dungeons and other structures can be adjusted, and biome boundaries can be changed.

Who it’s for: Server owners and map makers who want more control over how the world generates and what mobs appear than the default settings allow. Players on a managed server need no extra install.
