Mainlen is a Towny Survival Minecraft server with land claiming, skills, and player shops. Explore a main world plus separate Nether, End, and Bounty worlds; the main world never resets and is the only world with keep inventory enabled. Progress through 28 ranks split into four branches (7 ranks each): every rank adds +2 extra /sethome slots and increases backpack storage, with the final two ranks unlocking /feed and /heal; you can change your path with /rankdown. Mainlen runs in offline mode and includes a /remember option for easier future logins, and it also has PvP duel arenas that are currently not finished.
