I found a modded Minecraft server running a Chaos and Magic themed pack on 1.20.1. It is built for people who want magic and mayhem and a lot of weird moments while trying to survive.
It looks best with friends since you can team up to explore and build big magical bases. There are big bosses and creepy monsters plus wild creatures and dragons from Ice and Fire so you will be fighting a lot.
The server is whitelist enforced and it is 16 plus. If you like chaotic adventures and learning to control the madness this one fits.
