Item #: SCP-XXXX
Object Class: safe euclid
Special Containment Procedures:
SCP-XXXX is to be stored in an inanimate-item cell at site ██
Description:
SCP-XXXX is a 10th grade History textbook, 387 pages in lengh. The front cover displays a circular drawing depicting the Western Hemisphere, intersected down the middle by an Hourglass. Below the display, the words "Complex History of our World" can be read. SCP-XXXX's exterior is otherwise devoid of any content or Identifyers.
SCP-XXXX's contents seem to change anytime the book is closed, and none of the passages observed so far correlate with real events or have any cohesion amongst each other.
When opened at any page by a human subject, SCP-XXXX will seemingly rewrite the subject's previous existence so as to fit within the context of the page in question. This will include the individual's memories as well as any physical characteristics no longer consistent with the new "History" of the subject.
SCP-XXXX will however, have no effect on the real sequence of events or other subjects involved.
The Item's anomalous effects only manifest with physical contact, meaning its contents can be safely observed either directly or through external media so long as the action of opening the book isn't being performed.
Addendum:
The following are a series of tests performed on SCP-XXXX to examine the extent of its anomalous capabilities.
Test A - Date
Subject: D-26941
Procedure: D-26941 is instructed via intercom to open SCP-XXXX at any page, and to then read the contents of said page out loud
Results: D-26941 complies, and reads a passage pertaining the partition of the Ottoman Empire at the end of the First World War. The text differs considerably from reality however, and in it is described an alternative version of events, where the Sykes-Picot agreement is never enacted and much of the land is given back to local tribes. After finishing reading, D-26941 shows slight confusion at the mundanity of the task and is dismissed.
Analysis: The subject showed no inmediate effects. However, after being questioned by Foundation researchers, it was found that D-26941 had vivid memories of their brother, killed in ████ during the ██████████ terrorist attacks, far past his passing and up to the subject's incarceration. Furthermore, D-26941 seems to have no memory of the attacks themselves, or of many similar events.
