Dreamsphere Cages

Dreamsphere Cages are ancient, abandoned cages which both the player and any enemies can be teleported to using the Telesword. The areas missing a cage are Infinite Silver, Autumnal Resolute 2, Herakleia Depths, TenterHook, and Lil Big World which choose instead to teleport the player either under the map or far to the side both of which resulting in being voided. Dreamsphere cages can be entered by using the Telesword or by finding hidden teleporters in dreams such as in Ten-Mou, Ocean Lab, and Fissure Outpost.

The easiest way for the player to access a dreamsphere cage is to enable pvp using the :pvp command then, drop the Telesword and pick it back up thus teleporting them.
