Very Grim Fairy Tales

Item #: SCP-XXXX

Object Class: Safe

Special Containment Procedures: All instances of SCP-XXXX are to be kept in standard locked storage boxes. Access is reserved for security clearance level two and higher.
Instances of SCP-XXXX-1 that were created from contained instances of SCP-XXXX are to be kept in a single 10M by 10m enclosed room. Feedings should take place twice a day at dusk and midnight, using a blend of crickets and meal worms weighing twice total weight of all SCP-XXXX-1 contained inside the enclosure. Should any incidences of cannibalism be observed, then the lead researcher is to be notified.

Any wild instances of SCP-XXXX-1 found are be captured. Termination is not recommended unless it is confirmed that there are no nearby colonies of SCP-XXXX-1. Captured instances of wild SCP-XXXX-1 are to be equipped with a tracker and briefly released shortly before dawn. Should SCP-XXXX-1 return to a colony, agents are recommended to wait for full sunlight before terminating the colony.

Description: SCP-XXXX is one 129 mm × 198 mm paperback book. When observed through pictures, film and other media the entire item appears to be completely black. Tests via spectra-photometer reveal that the item absorbs all ultraviolet light in the visible human spectrum. However all sentient individuals shown SCP-XXXX describe the appearance to be an old copy of Grimm's Fairy Tales.

Tests verify that SCP-XXXX emits a form of (black box) radiation/waves that causes any creature within twenty (20) meters to perceive SCP-XXXX as something other than its actual appearance.

Subjects tasked with reading SCP-XXXX aloud report various children's stories, not all of which belonging to any version of Grimm's compilation of fairy tales. All readings of SPC-XXXX feature the consumption of flesh and often cannibalism despite whether such aspects were part of the original tales.

SCP-XXXX's anomalous effects activate after reading for approximately one hour. At which point, a tumor materializes inside the third ventricle of the reader's brain. MRI's given to subjects reading or watching SCP-XXXX. The tumor grows at a rate of ██mm per ███ while reading, and becomes dormant until reading is resumed. After 3 hours of reading the tumor appears to end its growing phase. At this point the tumor becomes neurologically active and independent of SCP-XXXX. Within the next hour, movement is detected from the tumor. Subjects report intense headaches during this period. All subjects attempted to commit suicide within ten minutes and had to be forcibly retained. During this period an opening appears, and what is now classified as SCP-XXXX-1 emerges. The creature begins devouring the host's brain matter, growing at an astounding rate until it has reached about 26cm in height.

After exiting the cranial cavity instances of SCP-XXXX-1 are immediately capable of flight, and if not already outside, will exit any enclosures. SCP-XXXX-1 posses some unknown ability to seek out other instances of SCP-XXXX-1. Autopsies and experimentation have been unsuccessful in understanding this 'sixth sense'. Captive instances of SCP-XXXX-1 have shown to understand the language of the host they sprang from, and can vocalize human speech. They retain some memories of any person they hatch from, usually about the person's identity, and will refer always to themselves as the deceased individual.

Wild instances SCP-XXXX-1 prefer to congregate in densely forested areas, but will always choose a lair close to large quantities of food.The size of prey the SCP-XXXX-1 will hunt seems to be proportional to the size of the colony. A typical colony lair is almost a tiny village of individual dwelling made the bone, fur, clothes, and skin of their victims. At the base of a lair, Foundation agents have record finding bones of rodents, small mammals, and children. SCP-XXXX-1 has exhibited particular fondness of human flesh. Since the discovery of the first colony in 19██ 75% of all neutralized colonies have been discovered in forests just outside of suburbs. Their area of habitation has reached across Germany, as far east as Poland, and more recently the American Midwest.

Colonies have been known to house up to 50 instances of SCP-XXXX-1, and it is hypothesized that colonies are only limited by the amount of food that can be obtained on a daily basis. Even brief shortages of food cause SCP-XXXX-1 to engage in cannibalism. Foundation agents observing both wild and captive populations note that there is no order to which instance is chosen to be consumed. Only that when the first instance hungry enough to turn on its own draws blood. The rest of the colony will follow suit, tearing off limbs while attacking other cannibals attempting to steal the dismembered body parts. Up to a quarter of the colony can be cannibalized as SCP-XXXX-1 will not stop attacking injured instances until it's hunger is sated.

Instances of SCP-XXXX-1 are docile when alone or in small groups, and exhibit playful or sometimes even mischievous behavior. interviews have revealed this behavior to be very purposeful. The creatures coordinate their pranks to turn individuals against each other while maintaining their own innocence. Testimonials from SCP-XXXX-1’s living victims reveal that the creatures use their antics to gain the trust of children while alienating them from friends and family. In one case a, now deceased, 7 year old boy was punished for cutting his sister's hair, breaking household objects and shouting at his parents before disappearing. The boy's remains were found a week later during a foundation raid on newly discovered colony ██ kilometers away.

Addendum: After performing a analysis on the book's cover reveal a few nearly invisible indentations depicting the name "M.C. D████████" //I can't think of any other names that would create enough relevance to a reader to warrant the inclusion of this bit.

Addendum 2: After surgery of Subject D-xxxx. Dr. ██████ was successful in removing ████████. Miraculously, ████████ still functions independent of its host. Continued Surgery of tumors reveal instances of SCP-XXXX-1 in undeveloped fetal stages of growth. specimens die hours after removal from the host.
