THE GRANDFATHER

Item #: SCP-TH-11-21

Object Class: Keter

Special Containment Procedures: SCP-TH-11-21 is to be contained within a 10m x 10m x 10m chamber at Site-TH-███. The chamber must be equipped with reinforced steel walls, ceilings, and floors to prevent unauthorized access. Access to SCP-TH-11-21's chamber is restricted to personnel with Level 4 security clearance or higher.

The chamber should be illuminated with low-level, constant lighting to ensure SCP-TH-11-21 remains visible at all times. Additionally, a dedicated video monitoring system should be in place to maintain constant surveillance. Any personnel entering the chamber must wear specialized noise-cancelling headgear to mitigate the effects of SCP-TH-11-21's vocalizations.

Description: SCP-TH-11-21, codenamed "The Grandfather," is a horrifying and enigmatic entity that assumes the form of a grotesque, spider-like creature. Its appearance is further characterized by a distorted set of eyes that bear an unsettling resemblance to a young girl's. These eyes emit an eerie, otherworldly glow and are often described as "windows to madness."

SCP-TH-11-21 is known to manifest in specific situations where individuals have been exposed to extreme, unknown anomalies or substances. Its presence is often linked to the convergence of mysterious circumstances, such as:

1. A group of explorers discovering SCP-TH-11-21 deep within an old, abandoned mine.

2. An individual becoming infected by an unidentified symbiote while camping in the unforgiving desert.

3. A subject being exposed to an unknown chemical in a bizarre, clandestine experiment.

The entity's most unnerving trait is its ability to manifest after the utterance of specific, cryptic words, the knowledge of which is closely guarded within the Foundation. Once visible, SCP-TH-11-21 emits an overpowering, nightmarish odor that invokes profound discomfort and nausea in those who encounter it.

Exposure to SCP-TH-11-21's presence results in severe psychological and physiological disturbances. Affected individuals begin to exhibit erratic behavior, including severe mood swings, self-mutilation, and increasingly violent tendencies. Victims report vivid and grotesque hallucinations, often involving nightmarish scenarios or the torment of loved ones. These effects worsen over time, leading to complete loss of sanity, self-harm, and, in most cases, suicide.

Addendum TH-11-21-01: The origin of SCP-TH-11-21 remains a mystery, and the motives of the entity are unknown. Communication attempts have been futile, and SCP-TH-11-21 appears solely compelled to inflict psychological torment on its chosen victims.

SCP-TH-11-21's malevolence, its capacity to manifest under specific conditions, and the severity of its effects make it a significant threat to containment and the well-being of individuals exposed to its presence. The Keter classification is warranted, reflecting the constant danger it poses. Ongoing research is dedicated to understanding and mitigating the entity's influence.
