All test cases but one have ended with the test subject’s suicide.ĭescriptions of SCP-513-1's appearance are largely unreliable. This sleep deprivation, along with the mental stress caused by SCP-513-1's behavior, invariably induces paranoia, aggression, hypervigilance, and depression. Upon the victim's awakening, SCP-513-1 flees as usual (see Experiment Log 513). Victims able to fall asleep before SCP-513-1's appearance report being physically assaulted by it. This “stalking” behavior inevitably causes extreme sleep deprivation, as victims are frequently disturbed by SCP-513-1’s presence in their quarters. Sightings of SCP-513-1 reoccur every 14 to 237 minutes. Questioning of bystanders indicates that SCP-513-1 is invisible to those who have not been exposed to SCP-513. Upon being sighted, SCP-513-1 reportedly turns away and runs out of view before disappearing without a trace. Roughly one hour after exposure, exposure victims begin to catch glimpses of SCP-513-1 when opening doors, walking past mirrors, turning their heads, or performing any other actions that result in a sudden change in visual perception. Exposure victims report feelings of being watched by an unseen entity and present elevated heart rates and blood pressure. A single scrap of paper was found along with SCP-513 (see Addendum).Īny noise produced by SCP-513 immediately induces strong anxiety in all sentient beings who hear it, regardless of their previous mental status. SCP-513’s clapper was firmly held in place by several strips of duct tape. SCP-513 was recovered by Agent ██████ while carrying out Containment Reestablishment Procedure Mu at Site-██. Attempts to remove the rust chemically or mechanically have had no success. No marks or engravings are visible on its surface due to the large amount of corrosion. Physically, SCP-513 is an unremarkable, rusty cowbell. If possible, SCP-513-1 is to be apprehended on sight. All other exposure victims may be terminated at their request. Any victim who does fall unconscious is to be terminated immediately.Ĭlass-D personnel are to be terminated at the first sign of mental degradation. Under absolutely no circumstances may exposure victims be administered sedatives or allowed to fall unconscious. No other personnel are to enter the cell during this procedure.Īny sentient beings exposed to SCP-513 are to be monitored by at least two security personnel at all times. If the gelatin cube shows any signs of degradation (such as rips, tears, splits, liquefaction, or mold), SCP-513 is to be immediately removed and suspended within a replacement cube by a team of surgically deafened Class-D personnel. Personnel performing the inspection are to wear earplugs and active noise-canceling earmuffs at all times while inside SCP-513’s cell. An emergency inspection will be carried out immediately following any earthquake, explosion, or sonic event grade 2 or higher. The gelatin must be inspected daily for any degradation or loss of integrity. Upon destruction, the loud breathing will cease.SCP-513 is to be suspended in a one cubic meter block of gelatin and contained within a soundproofed, climate-controlled cell. The only way to get rid of SCP-513-1 is to destroy SCP-513 by processing it through SCP-914. Attempting to get closer to SCP-513-1 will result in it vanishing. The sound of loud breathing can be heard and SCP-513-1 will occasionally be seen in the player's peripheral vision. However, all interrogations thus far indicate that SCP-513-1 is a tall, emaciated humanoid with abnormally large hands.Īfter the player rings SCP-513, SCP-513-1 will start stalking the player.

Test subjects are unable to provide complete accounts of sightings due to their exhaustion, degraded mental health, and disruptive hypervigilance.
