SCP-3297
Gramma Always Remembers.
Special Containment Procedures
SCP-3297 is to be held within a standard humanoid containment chamber. Cleaning of SCP-3297's containment cell is to be carried out once weekly only when it is dormant. The dormant state can be triggered by lowering the temperature of its containment cell below 20°C ten minutes before entry. No meals are to be provided.
SCP-3297 is to be visited by one D-Class personnel once a day for no longer than 1 hour. D-Class exposed to the entity are to be rotated on a weekly schedule.
Description
SCP-3297 is a member of an unknown species in the True Bug (Hemiptera) superfamily closest resembling Cicada (Cicadomorpha ), which disguises its arthropod appearance using a psychic illusion. SCP-3297 incorporates its insect biology into its human disguise by masking its apposition compound eyes as a pair of very thick and pale-opaque glasses, and membranous wings as a shawl. It possesses a chitinous brown exoskeleton, stands upright, and has 6 uniramous extremities. The first pair is used to grab and use items. The lower pair is used in locomotion, while the middle pair is atrophied, appearing to have become vestigial.
SCP-3297's disguise takes on the visual appearance of an octogenarian Caucasian female measuring 1.6m (around the same height as the entity) and looking to weigh between 70-75kg (the entity weighs 50kg). Though it has been known to change its disguise from time to time, curly white hair, floral patterns on clothing, flip-flops, and sunspots are a common feature. The entity's disguise does not extend to photos or videos taken of it in which it appears in its true form. The entity is capable of speech and is intelligent, referring to itself with various colloquialisms for grandmother.
SCP-3297 possesses mind-altering and reading capabilities, which thus far have only been recorded to work on humans interacting with it. SCP-3297 will plant false memories of itself onto a subject's mind as if it were their grandmother and gradually replace memories not involving itself. Planted memories are always pleasant and usually involve food, toys, or Catholic holidays. Though these memories are often inconsistent with most subject's histories and backgrounds, those under the entity's effects will not find these inconsistencies unusual and will treat them as factual events. Subjects previously exposed to SCP-3297 viewing the entity in its true form will still regard it as their grandmother.
The start of a memory manipulation event is marked by a sharp decrease in brain activity in exposed subjects. SCP-3297 will begin narrating the events of said planted memory in detail while subjects remain in a trance-like state. Once the memory has been narrated in full the subject will resume normal brain activity with dramatically heightened activity in the left prefrontal cortex, the part of the brain associated with happiness. Due to the disproportionate amount of memories SCP-3297 erases compared to the amount it plants, prolonged exposure to the entity may lead to negative effects. (Read Document 3297-232 for further details).
When not engaging in memory manipulation, SCP-3297 is very talkative and will engage in conversation if prompted. Common topics of conversation include weather, confectionery recipes, Bible passages, kittens/cats, and requests for knitting supplies. Despite its chattiness, SCP-3297 will not cooperate when interviewed and insists it is "just a regular old granny" when questioned on its origins and anomalous properties.
Addendum: Repeated tests reveal increased neurosecretory cell activity in the brain of the entity as it manipulates memories. This has lead Dr. Molina to theorize that SCP-3297 feeds on memories and implants positive ones in order to have a reliable food source willing to return to it after creating new memories with which to feed on.
