Limits

Limits, also called Voids, are a series of worlds within an infinite Chain of Limits that goes up and down. The Void or Limit in which the game takes places is called the "Sleeper".

The Surface
Also called the "Upper Limit". This is the limit the Sisters and the Hero can ascend to.

The Sleeper
The birthplace of the Sisters. The Sleeper is composed of Chambers, which are connected by strings. Previously called the Awake, this Void was the living place of dozens of Sisters, who died when the famine came and Color left the Sleeper.

The Nightmare
The Limit at the very bottom of the Chain of Limits, where Absolute Death happens&mdash;an existence without Color. The Brothers managed to ascend to the Sleeper from this place. It is unknown whether or not a soul is truly destroyed upon entering the nightmare, but it is unlikely, considering that The Brothers managed to escape it.
