SCP-XXXX

Special Containment Procedures:
SCP-XXXX-1 is to be disguised as a PETA building, guarded by 4 members of ATF Upsilon-1 "Salem Executioners" and 2 members of MTF Mu-13 "Ghostbusters" from 10:00 PM to 7:00 AM.

If any instances of SCP-XXXX-2 are located, the building is to be scoured with the assistance of said SCP-XXXX-2 instance if possible. If SCP-XXXX-2 is hostile, all SRAs¹ are to be immediately activated, and the instance is to be fired upon with a class III firearm² and contained in a thaumaturgically sealed quarantine unit at site-07.
Should all 150 quarantine units be full at any time, all instances are to be introduced to their human counterpart.

No personnel is required to enter SCP-XXXX-1 when testing is underway, except for D-class included in the test. Should any non-required personnel enter SCP-XXXX-1, the SCP-XXXX-2 instance related to them is to be immediately led to said personnel via touch.

SCP-XXXX-3 does not require procedures.

Description:
SCP-XXXX is 3 separate anomalies:

SCP-XXXX-1 is a large retail space located on the Pennsylvanian coast that, prior to containment, was open for leasing. If a human should enter SCP-XXXX-1's storage room space, an SCP-XXXX-2 instance is created.

SCP-XXXX-2 are incorporeal flying entities that are visually identical to their human counterparts, theoretically spiritual renditions of said humans. If SCP-XXXX-1 is left by SCP-XXXX-2's counterpart, SCP-XXXX-2 gains the ability to see and hear, seeking out its counterpart, and:

A. Fuse with their counterpart, producing SCP-XXXX-3

B. "Haunt" their counterpart, either out of satire or out of spite for their past mistakes. (According to said SCP-XXXX-2 instances) Fusing with their counterpart does not apply any physical or mental changes other than granting SCP-XXXX-3.

SCP-XXXX-3 is a single written note on an indecipherable solid chemical compound resembling paper. It normally depicts how one would die, however, if a human counterpart has already received SCP-XXXX-3, it is a message from the SCP-XXXX-2 instance.

SCP-XXXX was reclassified as Euclid following the discovery of hostile XXXX-2 instances.

Discovery:
SCP-XXXX was discovered after 35-year old Junis Williams, a GOC agent, had gone missing on the coast of Pennsylvania. The date corresponded with an urban legend that had formed, detailing a retail location that could "Tell your fortunes". The foundation became involved after the local police had arrived at the location, one of which was a foundation agent.

Everyone who entered the building was later amnesticized.
