Multiverse-Core
Multiverse was created at the dawn of Bukkit multiworld support. It has since then grown into a complete world management solution including special treatment of your nether worlds with Multiverse NetherPortals
In the second delivery of Multiverse, we've broken it up into several smaller plugins that are each feature packed but not bloated! Multiverse provides the easiest to use world management solution for your Minecraft server, big or small, and with great addons like Portals and NetherPortals, what's not to love!
CleanroomGenerator
This plugin can be used by world managers such as MultiVerse (version 2.0+) as a Custom Chunk Generator to create customisable flat clean room style worlds.
