Overview

Yibb-Tstll, often whispered of in the most prohibited tomes as “The Patient One,” is a gargantuan, tentacled entity of immense power. It is frequently depicted as a shadowy, winged figure surrounded by a multitude of lesser, writhing horrors. Unlike the more actively malevolent Outer Gods, Yibb-Tstll exhibits a detached, almost observational existence, though its presence inevitably induces profound psychological fracturing in human observers.

Behavioral Logic

The entity operates under a strict, non-Euclidean framework. When Yibb-Tstll manifests within a local reality plane, the following protocols must be maintained:

1. Reality Anchoring: All interactions must strictly adhere to the established Lovecraftian metaphysical laws. Standard physics are considered deprecated within its proximity.
2. Proximity Threshold: A mandatory 50-meter perimeter must be maintained by all personnel. Breach of this zone results in immediate cognitive instability.
3. Observation Protocols: Do not maintain direct eye contact with the “lesser horrors” surrounding the entity; they are known to feed on the neural pathways of observers.

Modern Anomaly Adaptation

In the context of the contemporary anomalous world, Yibb-Tstll is classified as a Class-V Reality Distorter. Current research suggests that the entity is not merely a biological organism but a sentient rift in the fabric of space-time.

“To look upon Yibb-Tstll is not to see a creature, but to realize that the space where it stands is actually a window into a colder, older universe.” — Senior Archivist Note, Sector 7

Containment Requirements

• Temporal Suppression: Keep the containment site on a staggered temporal loop to prevent the entity from synchronizing with our reality’s timeline.
• Psychological Shielding: Personnel assigned to this sector must utilize Grade-IV hallucinogenic suppressors to mitigate the risk of spontaneous “revelatory psychosis.”

Archival Status

Researcher Note: As of the current date, no formal SCP-Foundation style containment protocols have been finalized. The entity remains in a state of “Observation-Only” containment. Further research into its link to the Night-Gaunts and potential dimensional tethering is requested for the next quarterly update.
