I found this server called CaveMC and it is kind of insane. The whole overworld is just one giant underground cave world. There is no normal surface at all. Everywhere you go is caves biomes resources and hidden places.
It plays like enhanced vanilla with semi anarchy rules so it feels really dangerous. Survival is super brutal and only the players that are smart and careful last very long. People explore fight and try to control the best spots.
This is Season 2 so it is a fresh start and they added a lot of new stuff. The biggest thing is a new Wasteland dimension. It is not just a biome. It is a whole new place with its own special gear and huge mega structures that you can explore.
In the Wasteland there is a unique currency and its own economy so players can trade and build power in different ways. There is also a new spawn that matches the theme and a custom generated map that looks really cool and has special features.
If you like tough survival semi anarchy and living only underground this server feels perfect. It is all about exploring dark caves fighting for loot and trying to survive longer than everyone else.
CaveMC Season 2 Underground Semi-Anarchy

True Vanilla Semi Anarchy No Resets

FabricCraft is a survival server that sticks to real vanilla mechanics because it runs on Fabric. It is semi anarchy so you get a lot of freedom with only a few rules.
There are no land claims and there are no world resets so the world stays the same and players shape it over time. That means you will see trade alliances rivalries and raids and all the weird politics that come with it.
Hacked clients or mods that give you an advantage are not allowed. Griefing is banned within 1k of spawn and it is handled with active moderation instead of claim plugins.
There is also a creative world with no plots and no big space limits so people can test builds before doing them in survival. If you like speedrunning there is a manhunt mode you can play too. Simple voice chat is available for everyone on the server.
