Yonderland is a semi-anarchy survival server with a unique 8-year old map. The world evolved using several different world generation mods (Terralith, WWOO, Teraforged, etc) and is an experiment in combining anarchy play with a world full of huge megastructures and other surprises dotting the landscape.
With so much to see, Yonderland is a great map for exploration. Loot a giant megabuild, or move into it. As always, uncharted chunks await you (currently using William Wyther's Overhauled Overworld for the overworld + Incendium for the Nether and Nullscape for the End dimension).
Current datapacks include Nice Mobs Remastered Enchantments Encore, Dungeons and Taverns, and a few other quality of life packs. There is no economy mod or grief protection. Version is currently 1.21 but the Viaversion plugin is installed so you can play on any version.
