Posalon is a lore building Minecraft project where what you do ends up becoming part of the servers history. It feels like a big community story that keeps growing because players keep adding to it.
You can get involved in nation politics and even try to start your own nation. You can design planes tanks and ships with movecraft then test them in real battles. If fighting is not your thing you can use BreweryX and be a bartender or you can spread a new religion and see if people follow it.
This is not trying to be an average server. The whole point is that the community builds the world together and your actions can get written down in the wiki as part of the saga.
