I found Rai Nations and it is a session based nations server. Sessions run on Wednesdays Friday Saturday and Sunday. It feels nice if you do not want to fall behind after the first few days.
The server is about nations and people interacting. Diplomacy matters a lot and wars are rare and feel like a big deal when they happen. The rules are meant to protect what you build so offline raiding is not really a thing.
There is a merchants village where you trade credits for stuff. You can get all kinds of items like enchants and building blocks. Sometimes events happen in the village too.
There is also lore with Unknown entities. In season one Unknown was a main enemy and after the last battle it split into five fragments. They can show up during sessions and you never know what they will do like combat jump scares or strange deals.
The world has history and ruins from old civilizations. People also add to the story over time. The community is active with around 18 to 25 players at peak so you usually have someone to talk to or trade with.
