Onion SMP is a smooth survival server made for fun and long term progress. It tries to keep things lag free so playing feels clean.
The spawn looks really nice and it is built to help new players start out. You can also claim land to protect your builds so griefing is not a big worry.
There is a green zone for safer exploring and a red zone if you want more danger. The server has useful QOL commands like home auctionhouse and duels so stuff is faster and easier.
You can set chat and tab tags with the tags command. There is also a rankup system so you can move up as you play.
