This server is called CollideCraft Time Zero and it feels like you crash into some broken world where nothing is really safe. The whole dimension feels unstable and weird and time does not feel normal at all.
It is a semi vanilla SMP where you actually have to earn survival instead of getting it easy. There is lifesteal so every fight matters a lot because hearts are on the line. People can pick plugins so the server changes with what the players want.
There are factions and alliances so you can team up or just decide to betray others if you want to play that way. There is prox chat so you can hear people that are close and it makes everything feel more intense when you run into someone in the wild.
The server runs frequent events and the owner says there is way more hidden under the surface that you have to discover yourself. It is not really a peaceful starter world. It is more like a place where you join early and fight for your spot and try to keep it.
