SCP-5193 is to be kept inside a flame resistant unbreakable glove box secured inside of a room accessible only by class 4 personnel. SCP-5193 is not to be removed from the room without O-5 clearance, and will stay inside of the glove box when moved. For use outside of its original room, it is to be fitted on a trolley and moved with care. Tools may be inserted into the glove box only by an O5 and changes made to SCP-5193 must be made by an O5.
Description:
SCP-5193 appears to be an old, worn journal around 10 inches in length and 12 inches in width, and contains several page dividers labeled with several years, the oldest labeled "1200" and the most recent simply saying "Present," with intervals of 50 years between each divider." The journal isn't very thick, maybe 3 inches in total, however when looking through the journal you will find the page number doesn't seem to match how many pages you would expect. Opening the last page totals the page number as an 8 digit number, which varies based on where the journal is opened. The journal is filled from front to end with text written in pencil, with a layout similar to a modern day encyclopedia. The text seems to contain quick descriptions of past events, followed by a number with up to 22 digits followed by various letters. Events that happen as a result of another share the same numbers, however the letters vary. The letters seem to mark the placement of the event caused by the previous, an event ending in B would be caused by an event ending in A. The events in the journal change based off of the location of the journal, with a radius of around 100 meters. The text also seems to update every time the book is closed and reopened.
If an event is erased from or ripped out of the SCP-5193, any effects of that event vanish entirely, with the exception being death. If a death occurs as a result of an event and the event is erased, the victim of the event will remain dead with an autopsy showing the same cause of death. Memories of an event will remain even after it is erased, though files mentioning the event will no longer mention it. Events that precede an erased event are missing or completely different afterwards. Events that result in the creation of someone will cause that person to go missing without any trace, and any information on that person will also vanish.
