Kindlewood is a vanilla-plus survival SMP. Paper-based with a light plugin stack for quality of life -- not a kitchen-sink modpack, and no pay-to-win, ever.
The world features a massive fantasy-flavored biome expansion: 95+ new biomes on top of vanilla (Amethyst Rainforests, Moonlight Groves, Volcanic Peaks, Mirage Isles, and more), plus dramatically bigger mountain terrain. All server-side -- vanilla client, nothing to install.
Land claims keep builds safe, a quest line gives early-game direction, and a player-run economy runs through in-world chest shops plus RPG professions (Jobs). Ranks are cosmetic/convenience only. The community is still small, so there's real room to help shape spawn and be one of the first names on the server.
