I found a server called Eden MC and it plays like a nations server. It has a lot of minor mods that make the game feel more interesting.
A player started a new nation named Solutus and they are trying to get it going. Right now they do not have members so they are looking for people who want to join and help build it up.
If you like nation servers and you want a place to play then this one seems like a good spot to jump in and be part of a new group.

GG.MINEWIND.NET New Server IPChill Semi Vanilla Nations Server
I found a semi vanilla survival server that is faction based and pretty chill. It is cracked so more people can join and play.
The server has a few mods like Stellarity and it also has graves so you can get your stuff back after you die. If you like nations style gameplay you can join a group and work with other players.
There is a nation called Zenith that is recruiting players right now. You can apply to join their group or you can just join the server and play your own way.GG.MINEWIND.NET New Server IP
