This is a plain unmodded survival server that just got made today.
It is a fresh world and the main idea is simple survival with other players.
Right now it is looking for people to join since it is new and empty so far.

I found a server where the owner is trying to get a small group together. They want around five people to join and play.
To get in you need the Crackers Wither Storm mod and TACZ. It sounds like the whole point is to play together with those mods and just have people to team up with.
