Wroud

Run unlimited worlds on one Fabric server, like Multiverse on Paper, World Manager or Multiworld: create, list and teleport with commands. Every world keeps its own time, weather and game rules, and the End dragon, portals and maps work in all of them.

Dial ancient stargates to eight kinds of worlds: Wellspring, a fan-made take on Minecraft's Sift dimension, sky islands with glowing heart trees, frozen wastes, molten depths and more. Vanilla potions and armour beat every hazard. Needs the Worlds mod.
