I found LichCraft and it is a Java semi vanilla SMP on 1.21.11 with a fantasy vibe. The world is built up by the community and there is a big spawn city that players made together.
It has custom boss fights made with MythicMobs and special drops. They are working on more stuff like instanced dungeons and custom items like a Healing Wand and a Fireball Wand plus teleport crystals.
Survival feels fair because you can protect your land with claims and you start with a lot of blocks then earn more by playing. There are timed gravestones so you can get your gear back. Admins try to stay out of the way and big changes need an 80 percent community vote.
People connect everything with ice highways nether portals roads and shared builds. There is also a live map so you can see what is going on. The economy is player run with shop hubs in spawn the Nether and the End and you can buy a shop plot with diamonds.
Rules are simple be kind do not cheat and do not lag the server. VPNs are not allowed.
