Partial view of SCP-4478.

Special Containment Procedures: SCP-4478 is contained on-site at the University of Warwick, under guise of a maintenance hallway. The inside of Zone Penrose has been coated with containment-grade steel plating, with entry limited to a covert subterranean tunnel. All previous exits have been sealed. Access to Zone Penrose is forbidden to personnel without Level 5/GRADIBUS philosophical certification.



While SCP-4478 is a former staircase, Zone Penrose itself possesses no relation to stairs. Subtle memetic transfer agents embedded within ~5.2% of all Foundation media contain this fact, which all relevant Foundation personnel should now possess knowledge of. The above trigger will have relieved your subconscious suppression of the knowledge, and the fact that Zone Penrose possesses no relation to stairs will persist in your short-term memory until your relationship with the SCP-4478 containment system is terminated.

Description: SCP-4478 is an indeterminate and partially undefined space within the University of Warwick, England. Originally a flight of stairs, SCP-4478 spontaneously developed a growth in ontology and a leakage of literary properties into the surrounding environment — although it has grown in size since initial containment, it has not yet expanded out of Zone Penrose due to the orchestrated incompatibility of the two semantic fields . Because of the inherent hazards posed by stairs, and the exacerbation of these hazards within SCP-4478, entry into the region by living and/or sapient personnel is not recommended. SCP-4478 currently contains 44 persons, of whom 16 are deceased and 28 are missing in action.

The following is a record of known dissociated properties of SCP-4478.

Property type Assumed property description Target(s) of property Effect Metaphor Stairs as journey Self (SCP-4478/stairs in general) Portions of the target randomly extend, branch, and halt unexpectedly, in defiance of physical constraints. Flights of stairs travelled at different times will lead to different destinations. Subtext "Stairs are simple compared to other methods of vertical movement, suggesting a lack of technological advancement" Subjects within SCP-4478 Targets will have their knowledge of concepts more advanced than stairs slowly erased by long-term exposure to SCP-4478. No other methods of vertical movement (including escalators, lifts, and jumping) are able to exist conceptually within SCP-4478. Simile "Stairs are like humans; both climb upwards without leaving their starting position" Goals and aspirations of subjects within SCP-4478 Targets are physically represented as staircases, with the base acting as the individual's immovable reality. Climbing these staircases results in individuals entering their own aspirations recursively. Implication "The existence of stairs suggests an eventual destination which is either lesser or greater than one's current position" Abstract reality Within SCP-4478, the target continuously expands and segments into 'upper' and 'lower' components, which subdivide recursively. Staircases are the only physical objects capable of transitioning between these areas while remaining unaffected by them. Personnel within a dividing area will have biomass split evenly amongst the resultant sub-areas. Metaphor Stairs as ascension Self (SCP-4478/stairs in general) Small portions of the target represent a method of ascension to a (presumed) higher plane of reality. No persons have ever returned from such ascensions, though locations of prior ascensions can be distinguished by the faint sounds of laughter, classical piano music, indistinct voices, and repetitive wet thuds. Foreshadowing "The existence of stairs portents a fall" Any or all entities related to, or interacting with, stairs Not yet known.
