Dimensions

Dimensions are separate world-sized biomes accessible only by using a certain item (the teleportation item) to teleport there (with some exceptions).

False Dimensions
False dimensions are areas that can be considered dimensions, and have their own teleportation items, but can be accessible in methods other than their item.

True Dimensions
True dimensions are areas that are dimensions that actually need the player to enter using their teleportation items.
