The cave
Containment: It’s a cave that seals itself off from the outside world when possible. It contains itself, but SCP officers live on a farm above the cave, keeping an eye on its inhabitants. The cave is to be left alone or it would send black water people to kill intruders unless Ina calms it down.
Description: On 05/03/20XX, an archaeologist team discovered a cave based civilization. The cave was natural, filled with artificial rooms that had a resemblance to modern day low income housing with extreme parkour and climbing skills required to move between stories. The wooden support beams were carbon dated, revealing the older ones to be from before the last ice age, but the newer ones have been freshly cut. In between trips to investigate, the cave would have healed itself up to a kilometer away from the cave, so the team had to remake the entrance to the cave upon every visit. This, of course, made them dread going back to camp to the point that they had to have someone down there at all times to prevent it from closing itself up again. However, they were only capable of reaching the third top floor. The third floor was a mass grave with skeletons laid out on blankets across the floor, leaving a small gap to walk around them. Luckily, Ina made a basic map of the fifty three floors, indicating where the original entrance was and where the black water pond was. The labels are undecipherable. The map shows a caved in entrance that seemed to lead to the farmland of whoever lived in the cave. The other side of the entrance is currently under the ocean, and there’s evidence of failed crops. To this day, Ina claims the cave has its own consciousness and they have a symbiotic relationship.
Ina (eenuh)
Containment: She is allowed to roam free within 50 kilometers of the cave, not that she willingly does any different. She is to be monitored outside the cave for her own safety, as she blindly trusts strangers.
Description: During the third visit, archaeologists found what looked like a blond haired, piercing green eyed girl that had two sets of extra arms and an extra pair of feet on her knees. Her eyes were also black where most eyes are white, and she had no pupils. She was usually spotted with Chapu, a wolf too large to be from modern times. She loves to write, though deciphering her writing has caused many to go mad. She is naive, blindly trusting the first outsiders she sees, which has been cause for some problems in her recent past. She is half human, the other half being of unknown origin. Her chemical make up is DNA and black water, an unknown black liquid substance that mimics water, but defies physics a lot. She has three reproductive tracts, two female, one male. She only has female DNA. She farms a lot and freaks out if somebody skips a meal. She loves to make people happy and can learn languages within a matter of days. She seems upset and lonely all the time.
History: For the first few attempts at communication, the girl ran away, clearly terrified, and she ran around the cave with ease. She slowly warmed up to the archaeologists enough for them to get her to the town they thought at the time she was from. Noticing how everyone was afraid of her, she retracted her extra arms and feet. Shortly after, she was taken by a human trafficker, who used her eyes as a selling point to an unknown man in the United States. A week later, she escaped, getting enough tranquilizer fluid from darts to kill an elephant. She ran into a cave a few minutes before a cave in trapped her, her wolf, and a class of highschoolers inside with a brown bear. When the bear attacked, Ina and Chapu promptly killed it without any weapons. A few seconds later, they both fell into comas so deep that they were mistakenly pronounced dead by the hospital. Ina regained consciousness during her autopsy and ran until the SCP foundation caught her. At first, the only languages she spoke were long extinct, but she learned English within a few days of captivity. She constantly looked for Chapu and complained about wanting to go back to her cave. She had mostly free range, but she was usually in her room, writing. At that point, she hasn't healed any from the autopsy. Eventually, a black water creature was willingly absorbed into her in order to provide the materials Ina needed to heal. After she was allowed to move back into her cave, she often came out to tend the farms of ill farmers. The seeds she plants grow into alien looking super nutritious plants that have been extinct for thousands of years. She was even given her own farm to supply food to fight world hunger. Some SCP officers live on the farm to keep her company.
Chapu (choppoo)
Containment: She is to be either in the cave or monitored by Ina for the safety for others as Ina is the only one who can calm her.
Description: Chapu is half wolf, the type of wolf being long extinct. She is Ina's half sister on the unknown DNA side. She is protective over Ina and gets extremely aggressive if the two are separated. She often follows Ina's command like a dog, but shows cognitive ability beyond that of a human. Ina was the only one who ever knew how to calm Chapu down before she attacked anybody. Ina claims Chapu is older than her by exactly one year. Her coma is unexplained, but she woke up at the exact moment Ina did, promptly finding and following Ina. She often escaped her enclosure in order to be with Ina or hunt nearby wildlife. Chapu often gave Ina her prey for Ina to turn the skin into paper. Ina often gave the skinned prey back as Ina had no need for sustenance while Chapu did.
Black Water People
Containment: They are allowed outside the cave only when serving Ina. Otherwise, they are to be held in airtight storage as they have the same capabilities of escaping as sentient water.
Description: The black water people are a hive mind of humanoid black water creatures with a sole purpose of protecting the cave and serving Ina. Unlike Ina, the black water people have no DNA, so they have no color or sound. As soon as Ina leaves the cave, the black water people come out of the bottom of the cave and slay any outsider to enter the cave. Hundreds of black water people left the cave in search of Ina when she woke from the coma. These ones were peaceful, but were unable to communicate, so they terrified many. They would linger over people in their sleep, leaving when they moved. They stopped being sighted after Ina returned and the cave was left alone except when they help Ina with the farms.
