Item #: SCP-4XXX
Object Class: Safe.
Special Containment Procedures: SCP-4XXX is to be kept in the Hazardous & Dangerous Items storage at Site-48 along with all other related instances. It may only be accessed by Head Researcher Dr. Brian Anderson with written approval from any O-5 Council member. It is to be monitored by security staff daily for any disturbances.
MTF Epsilon-5 "Time Police" are to monitor for activity relating to the frequencies emitted by SCP-4XXX instances around the world. MTF Epsilon-5 are to deploy within twelve hours to any location where such frequencies are found. Any persons carrying or currently using SCP-4XXX instances are to be considered hostile and are to be contained with lethal force. Any instances of SCP-4XXX or instances similar to SCP-4XXX-2, SCP-4XXX-3, and SCP-4XXX-4 found are to be contained in a similar manner as detailed above.
Because of the nature of SCP-4XXX's origin, there is currently no method for quantifying the number of instances that exist or could possibly exist. As such, full containment of SCP-4XXX and its users is not possible at this time.
Description: SCP-4XXX is a disk shaped object comprised of unknown metals measuring 13.4874cm in diameter and is 2cm thick. In appearance and touch, the object most resembles stainless steel. Hardness tests using the Knoop hardness test has revealed an HK value of 6900.1
SCP-4XXX's anomalous properties occur when held by a human being and is otherwise inert. The object allows its user to traverse time and space. Tests with Dr. Brian Anderson have confirmed the effect is catalyzed by human thought when held. This involves concentration revolving around a person, exact time, and place. These tests have also proven that focusing on deceased persons will place the individual using SCP-4XXX into a reality where that person is still alive. These realities are usually very similar to our own, with only slight deviations.
Before the user is transported in time and space, certain frequencies are emitted at both the origin and destination of SCP-4XXX. These waves are now named Andersonian waves in honor of Dr. Anderson who achieved the discovery. Andersonian waves are observed as errors in other sound-based listening equipment and cause static in analog radios.
The object was confiscated after the detention of the object's user, who will hereby be referred to in this document as SCP-4XXX-1. SCP-4XXX-1 was detained after using SCP-4XXX, SCP-4XXX-2, SCP-4XXX-3, and SCP-4XXX-4 to carry out a series of murders across multiple decades spanning the years 19██ and 20██. Refer to Incident Report 14142.1 for information regarding these events. For information regarding the non-anomalous technology found on SCP-4XXX-1, refer to Item Log 22214.
After SCP-4XXX-1 transportation to a temporary holding cell at Site ███, Dr. Brian Anderson conducted an interview seeking more information about the subject's origin and the origin of SCP-4XXX.
