This server is called Samsara and it feels like a big story world someone has been building forever. The owner has been working on the map since around 2013 using Worldpainter and it is all made by hand. The world is huge and has different layers of caves and strange biomes that are meant to be explored in survival.

The gameplay is kind of vanilla plus. You still play normal survival but there are extra things like mob heads voice chat graves and custom mobs. The world is made so the biomes are the right size for survival and not just giant empty zones.

There is also a custom questing plugin that the owner made over the last months. It gives you a story and reasons to go explore secret ruins and places that you can find on your own. The server is meant to feel fresh weird poetic and sometimes really cool to look at.

You start in a place called SpawnHenge and from there you just go your own way. It is free to play and all about immersion and discovery instead of pay stuff.
