|Valley of Screams|
The Valley of Screams (also known as "Kyogoku") is a dimension that forms between the World of the Living and the Soul Society, stemmed from the Precipice World. It can only be accessed from the World of the Living. Blanks resided in this place, separated from their memories, until they come in contact with the Memory Rosary. Its appearance is a regular occurrence that happens naturally due to souls getting lost trying to get to Soul Society.
The Valley of Screams looked very similar to the underground Training Area created by Kisuke Urahara, only the size of it was on a worldly scale. The area in which the main event of the story took place was a rocky area with many canyons and mountains.
