Lumenor SMP is a 24 7 custom vanilla survival server on 1.21.11 and it also lets newer versions join with ViaVersion.
It works for Java and Bedrock and even cracked clients so it is easy to hop on.
The cool part is the role system where you pick Passive for peaceful play or PvP for chaos so different types of players can live together.
The world has custom biomes and huge structures like ancient temples so there is a lot to explore and find.
There is a player driven trading shop that feels more like bartering and not a big server economy. There are PvP and Passive arenas where keep inventory is on in the arena so you can practice without losing your stuff.
You can also get custom armor trims that give small buffs and the Nether is made to be very challenging. They also say they have strong anti cheat to keep things fair.
The server is hosted in Germany and the staff team is from Greece France Sri Lanka and Sweden so players from lots of places fit in.
