Space

Space is a layer appearing at the top of the world: ~950 feet and above, for large worlds. Gravity is decreased in Space, which means the player can jump higher, and will fall slower, similar to the Featherfall Potion effect. The sky is dark and stars are visible, even when the Sun is still up.

As with all high-altitude locations, Harpies and Wyverns will spawn. Space does not generally contain any naturally-placed materials.

In Space, air apparently still exists, so the breath meter does not appear.

Possible methods of getting to Space are use of a Gravitation Potion, Wings, or building a pillar of Blocks. Rocket Boots will often get a player there when used from a Floating Island.
