This can be run with or without a normal terrain mapgen, allowing pure skylands or an exotic addition to the landscape.
Configurable settings include the altitude islands appear, the ability to restrict the area they spawn, and whether rare and giant trees can sometimes be found growing from islands.
Vines, or something that contains vines, such as plantlife_modpack or MineClone2. These will grow off the sides of the islands, climate permitting, allowing you to climb, and looking picturesque at the same time!
Teleportation or Nether mod for entrances into floating kingdoms.
Extra ways to explore:
- Bridger if you want to build nice wooden bridges between islands
- Airboat to sail the high clouds on a small airship
- Flying carpet
