Valley of Screams

The Valley of Screams is a dimension that forms in between the Human World and the Soul Society, stemmed from the Dangai Precipice World. It can only be accessed from the Human World. Blanks resided in this place, separated from their memories until they come in contact with the Shinenju. It is a regular occurence that happens naturally due to souls getting lost trying to get to Soul Society. The Dark Ones claimed this to be their homeland until they would invade the Soul Society. The Shinigami that came here to help Ichigo Kurosaki rescue the Shinenju were Renji Abarai, Rukia Kuchiki, Byakuya Kuchiki, Tōshirō Hitsugaya, Ikkaku Madarame, Yumichika Ayasegawa, Kenpachi Zaraki, Yachiru Kusajishi, Soifon, Izuru Kira and Shuhei Hisagi. It 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 in an rocky area with many canyons and mountains.

In the movie Bleach: Memories of Nobody, the Valley of Screams expands to a point where it connects Soul Society and the Human World. The Dark Ones attempt to collapse this dimension in a bid to destroy Soul Society in order to gain revenge for their exile over a millenia prior to the story.
