Koval Hub is the hub for three servers: MurelReborn, Vimcraft Revived, and PureSurvival. It supports both Java and Bedrock, and the sub servers accept versions from 1.8 up to 1.26.1.1, so most players can hop in without much trouble.
MurelReborn is the big one, rebuilt from the ground up with eight different worlds. You get classic survival worlds, amplified terrain, secure Plots that never reset, and harsher worlds like DeadWorld, WinterLand, and Hell for players who want a tougher co-op challenge. Worlds 1 to 4 and Plots share inventories, while the harder worlds keep their own separate inventories.
Vimcraft Revived brings back that old school survival feeling with a weekly wild reset, plots that stay safe, and a more classic playstyle. It mixes Survival, Minigames, and Plots, with the focus kept on building, surviving, and hanging out rather than pay-to-win nonsense.
PureSurvival is exactly what it sounds like: plain vanilla Minecraft with a massive island world and simple survival gameplay. If you just want something clean and straightforward, that server is the easy choice.
