SCP-4143

Item#: 4143 Level3 Containment Class: euclid Secondary Class: none Disruption Class: ekhi Risk Class: danger link to memo



Special Containment Procedures: Chen Lin is housed in a standard humanoid anomaly containment cell at Site-201, equipped with newly developed holographic entertainment systems and furbished as per Lin's requests. The cell exterior is outfitted with Kant Counters and AetherV3 Thaumic Particle Imagers, set to alert changes in chamber conditions as an early warning for defecation. Lin is permitted to leave the cell while accompanied by guards trained in handling dimensional anomalies. Interviews with Department of Extrauniversal Affairs (Multi-U) personnel will be held monthly.

Lin has been instructed to trigger their cell's alert system if they need to defecate. Once done, they are to be rapidly transported from Site-201 to Multi-Hazard Chamber Zeta in the Arete Dimensional Array. Chamber Zeta is constructed to withstand various anomalous hazards, containing beryllium bronze antenna to redirect psionics, counter-memetic glyphs inscribed into the walls, three redundant auto-exorcist units, and one lavatory. Anomalies released from defecation are to be contained or neutralized through all necessary means.

In the event that defecation poses a K-Class hazard, Array regulators will be disabled and Chamber Zeta will be jettisoned into the nearest dimensional aperture. Lin's survival is not considered a priority.

Description: SCP-4143 is the intestinal tract of former graduate student Chen Lin, which continually generates additional body mass and extends through multiversal and higher-dimensional spaces. The small intestine entirely fills the cavity both intestines would normally occupy, entering a localized wormhole at its 8.5m mark. The sigmoid colon exits through a nearby wormhole, connecting to the rectum and anus.

Preliminary autonomous exploration on 29/05/2038 found that SCP-4143 spanned a length of 30m, intersecting 4-dimensional space twice and passing through one alternate universe. Ectoentropic generation of new matter exponentially increased in the following weeks, leading to a 110m length by 10/06/2038 and 1km by 20/06/2038. Following this point no explorations have reached the end of the tract; all dispatched probes have been destroyed by anomalous phenomena or have lost contact. The current intestinal length is unknown.

Initially, the tract matched the anatomy of non-anomalous intestines, maintaining the same proportions for each segment as it expanded. However, with repeated dimensional intersections it has generated a varied structure, incorporating aspects of the areas it enters and altering to follow constraints from local laws of physics. Refer to Addendum.4143.1 for further information.

Chen Lin last defecated on 14/06/2038. The process, while not harmful to the subject, released three incorporeal empyrean entities and a miniaturized warhead with the potential to instigate an NK-Class "Grey Goo" Scenario. With anomalous phenomena continuing to build in the intestinal tract as it expands, the risk of hazardous anomalies being imparted onto feces increases significantly. Preparations for the next defecation event are underway.

Despite expected health complications that could arise from extradimensional organ displacement, Lin does not experience any adverse effects from the anomaly.

Addendum.4143.1: January 2039 Exploration Findings

The following is an abridged overview of findings within SCP-4143, found using the ENR1 Gastrointestinal Probe from 03/01/2039 to 09/01/2039. Contact with the probe was maintained via microscopic relay beacons implanted into the intestinal linings or released into any present cavities. Findings are marked by which dimension or universe the section of the intestine is in, with the lengths of these sections recorded when possible. Sections not of note are excluded.
