SCP-4000 Proposal

Item Number: SCP-4000

Object Class: Keter

Special Containment Procedures: SCP-4000 is to be contained within an Incorporeal Entity Vacuum Chamber at Site-42. SCP-4000's containment cell is to be fitted with 3 Non-Physical Displacement Neuralyzers. Personnel assigned to interview SCP-4000 are required to possess a robust understanding of 19th-century American politics and any items utilized for SCP-4000's entertainment are not to provide any information about contemporary politics.

In the event that SCP-4000 breaches containment, Foundation operatives embedded within the United States Secret Service are to be immediately notified. For the duration of the SCP-4000 containment breach event, the President of the United States is to be kept out of Washington DC and is to engage with the press as minimally as possible in order to prevent SCP-4000 from learning his or her whereabouts.

During an attempt by SCP-4000 to possess the president, Foundation personnel are to carry out banishment rituals in accordance with Shawnee tribal traditions. In the event that recontainment of SCP-4000 fails and SCP-4000 successfully possesses the President, the Rhea Protocol is to be implemented within 36 hours.

Description: SCP-4000 is a Class-1 incorporeal entity that claims to be William Henry Harrison, the 9th president of the United States who died a month after taking office. SCP-4000 displayed deep knowledge of the life of Harrison, including his service in the War of 1812, as the first governor of the Indiana territory and as minister to Gran Colombia. SCP-4000 has consistently expressed great disappointment that it was unable to finish a term as President of the United States and a desire to take on said role as soon as possible. Over the course of containment, SCP-4000's mental state has significantly degraded.

SCP-4000 seeks to take control of the body of the individual currently serving as President of the United States. The initial manifestation of SCP-4000 occurred in 1921, exactly 80 years after the death of President Harrison, though it was not properly analyzed and classified until 1923. SCP-4000 has made no fewer than 9 attempts to possess the then-current president and has successfully done so on 3 occasions. Prior to the successful development of the Incorporeal Entity Vacuum Chamber, containment protocols were geared towards warding off SCP-4000 via exorcism rites or trapping SCP-4000 in one body that would be kept alive as long as possible, utilizing life-extending techniques as needed.
