The Box of Whispers

Item: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be kept in an isolated room in Site-19 with heavily monitored levels of temperature and humidity. The room must also be padded with sound dampening foam, ceiling and floor included. All handling of SCP-XXXX is to be done with gloves and extreme carefulness. All handling of SCP-XXXX is to be authorized by Class B Personnel or higher, per orders of Doctor Alan Colter. Personnel must wear ear protectors at all times when assigned to SCP-XXXX. Employment of deaf personnel is also recommended. Preferably, all personnel charged with mantaining, guarding, and testing SCP-XXXX should be deaf.

SCP-XXXX is to be placed in a small table on the center of the room. Under no circumstances is the crank on the left side of SCP-XXXX to be turned. Further experimentation on SCP-XXXX is prohibited without authorization of class B personnel or higher.

Description: SCP-XXXX is a 15 note nacre music box with a crank on its left side. The crank can be turned in both directions and doesn’t seem to affect the way the music is played. It takes 6 pulls of the crank of SCP-XXXX to hear its song fully. The box was seized by Foundation personnel on 3/15/20██, in ██████, Russia, at the site of the murder of a married couple within their antique store. Amnestics were administred to police officers and journalists as needed in order to remove the details of the murder from all official accounts. Below is the official police report, before Foundation intervention (translated from russian):

On Monday, March 15, 20██, the bodies of ██████ █████████ (79), and █████ █████████ (76), were found within the █████████ antique store, which both victims co-owned, their heads violently removed from their bodies, nowhere to be found. Signs of struggle around the store seem to suggest assault. The only item within the store that wasn’t damaged was a small nacre music box, and the small coffee table it was placed upon.

The anomalous properties of SCP-XXXX can only manifest when either of two criteria are met:

Criteria 1: The song of SCP-XXXX is played and heard by a human capable of hearing. The specific details of how SCP-XXXX’s anomalous properties manifest vary depending on the lengh of the song and in which direction the crank was pulled.

Criteria 2: An attempt to damage or destroy SCP-XXXX occurs. SCP-XXXX’s anomalous properties will manifest regardless of whether these attepts were intentional or accidental.

SCP-XXXX is virtually indestructible. It is theorized that a sufficient ammount of force could destroy it, given its aparent hostility towards attempted damage. This theory hasn’t been put to the test given the nature of both SCP-XXXX and the Foundation.

SCP-XXXX has been noted to remain undamaged after:

-Falling from a height of 10 feet (3 meters)
-Being thrown against a wall
-Having an iron weight of 33lb (15kg) dropped on top of it.

Further experiments to test SCP-XXXX’s resilience are not recommended given SCP-XXXX’s responses to these experiments.
