This server is called Campfire SMP and it is made for players who are 18 or older. It is a small community server that wants to last for a long time and not reset all the time. The world is survival and feels very close to normal Minecraft.
The server runs on Purpur 1.21.9 and is self hosted with strong hardware so it can stay up all day. There is a 20k by 20k world border so there is still a lot to explore and it will grow when big updates come out.
They use a few plugins and data packs to keep things safe and fun but not too crazy. There are no commands like tpa or home so you have to travel and explore for real. There is a diamond based economy and a shopping district plus a nether highway so people can move around fast.
The community already has cool areas like a battle arena and a Christmas area and other shared projects. Players like to hang out together and talk a lot using voice chat and Discord while they work on builds or play other games.
Most people on the server are in their twenties and some are older so it feels more relaxed. The goal is to have a friendly long term SMP where you can join and feel like it is your Minecraft home for years.
