Overview

We're running a Minecraft NeoForge 1.21.1 server in creative / peaceful mode, so there are no enemy mobs.

The server has a lot of mods installed. Here are some of them

Cobblemon, which adds pokemon and battles to the world
Create, adds a bunch of mechanisms and stuff
Create Aeronautics, lets you build physics contraptions such as airships and cars
Distant Horizons, lets you look at really far away chunks

This isn't a complete list at all.
