Per 
Special Containment Procedures: SCP-XXXX is kept surrounded by five Scranton Reality Anchors at all times. The Reality Anchors were put into SCP-914 and refined to "fine" before being put to use. SCP-XXXX-1, SCP-XXXX-2, SCP-XXXX-3, SCP-XXXX-4 and SCP-XXXX-5 are kept in containment Site-██ where they have been provided with living quarters, entertainment (according to their requests, a gaming setup and a television). Only after the approval of an O5 command member are SCP-XXXX-1, SCP-XXXX-2, SCP-XXXX-3, SCP-XXXX-4 or SCP-XXXX-5 to be allowed inside the active zone of SCP-XXXX.
Description: SCP-XXXX is a burnt castle in ███████, Italy. SCP-XXXX has been observed to have taken no structural damage even when bombs of various sizes were detonated inside of it. Detonation of a hydrogen bomb was requested by Dr. ███████. Request denied. SCP-XXXX is able to successfully contain any entity that is placed inside any room in it. Different entities are contained with different methods but aAll the doors of SCP-XXXX change their size according to the size of the entity that is in front of it. There is a door in the second floor of SCP-XXXX which leads to a room containing a bookshelf which has books written in an unknown language. The books in SCP-XXXX were sent in for decryption and have not been decrypted yet. The bookshelf in the same room cannot be moved by anyone except SCP-XXXX-1, SCP-XXXX-2, SCP-XXXX-3, SCP-XXXX-4 and SCP-XXXX-5. There is a door behind the bookshelf which, although can be opened by anyone, causes the individual who is touching it directly to be transported to a random place on Earth. The door is made of [REDACTED]. The door cannot be opened from the inside the room behind the door. All the rooms in the castle adapt according to the entity that is inside them.
The five individuals of American origin, termed SCP-XXXX-1, SCP-XXXX-2, SCP-XXXX-3, SCP-XXXX-4 and SCP-XXXX-5, all of fifteen years of age and male, while appear as normal human beings, acquire powerful reality warping abilities when in a 30 metre radius of SCP-XXXX. SCP-XXXX-1 is able to control the amount of control any reality warper has over their abilities. (See Addendum XXXX-1 Test Logs). This effect stays even when SCP-XXXX-1 loses his abilities on leaving the active area of SCP-XXXX. All of them are extremely co-operative during tests involving SCP-XXXX. Interrogation logs reveal that there were two more reality warpers inside SCP-XXXX.
"SCP-XXXX-7 is a sentient being whose reality warping abilities were so immense that he could've caused a Z-K Class Reality Failure scenario if he wasn't stopped. So you’re welcome." said SCP-XXXX-6 during an interview session with Dr. Schiller. SCP-XXXX-6 has not communicated since. SCP-XXXX-6 was described by SCP-XXXX-4 and SCP-XXXX-5 as "a black smoke cloud that came out of a box, took the shape of a human and disappeared." The box in which SCP-XXXX-6 was contained is yet to be found. SCP-XXXX-5 described it as "a small wooden box and nothing else." According to their descriptions, SCP-XXXX-6 was a being capable of psychic abilities. The whereabouts of SCP-XXXX-6 are currently unknown.
Discovery: SCP-XXXX was discovered in Italy when a Serpent’s Hand member, after killing a civilian, tried to kill one of the people in the crowd but stopped in their tracks and committed suicide. The body disappeared immediately. An agent in the area alerted us of the situation and we sent a Mobile Task Force to provide amnestics to all the witnesses but none of the witnesses recalled any memory of the incident except ten adults and five children. Dr. Max Schiller instructed the MTF team to not give amnestics to the fifteen individuals but to observe their actions until further notice. Two hours and seven minutes after they had gone into the hotel where they were residing, the five children came out of the hotel and were seen walking towards the castle beside the hotel. When the task force tried using thermals to track the children who were inside SCP-XXXX, the thermal camera malfunctioned and a team of five foundation operatives were sent in to follow the children. Communications and recorders malfunctioned when the team was inside SCP-XXXX. Dr. Schiller instructed the MTF team to send in more operatives inside SCP-XXXX. The foundation operatives were not able to enter SCP-XXXX as there was an invisible "barrier" stopping them. After one hour and thirty-two minutes, the five foundation personnel were seen emerging from SCP-XXXX with the five children. One of the children, SCP-XXXX-5 said, "We know everything. We know who you people are. Just take us into containment." They were then taken to Containment Site-██ where they were provided with living quarters and clothes. When asked about what happened inside SCP-XXXX, the five foundation personnel reply that they do not remember anything but a “huge explosion” that they saw when they entered the castle.

Interview Logs
Test Logs
| Test XXXX-1 | |
| Aim | To understand the abilities of SCP-XXXX-2. |
| Protocol | SCP-XXXX-2 was placed within a 30 metre radius of SCP-XXXX and told to open a portal to the 2nd dimension. A bright sphere of white light appears. A remote controlled toy car is sent into the portal. |
| Results | The toy appears to have become two dimensional. When driven, the car can only move along its x-axis and z-axis. When viewed from above, all the internal workings of the car are visible. The car can still be controlled using its remote. It is clear that the car is fully two-dimensional since when three-dimensional object passes through the car without any resistance when it is travelling through the z-axis. But when a three-dimensional object is passed through the x or y-axis, it collides with the car. |
| Test YYYY-2 | |
| Aim | To understand the abilities of SCP-XXXX-1 |
| Protocol | SCP-XXXX-2 and SCP-XXXX-1 were both placed in a 30 metre radius of SCP-XXXX. SCP-XXXX-2 was asked to open a portal to the 2nd dimension and SCP-XXXX-1 was asked to decrease SCP-XXXX-2’s control over his abilities. A dull sphere of white light appears. A remote controlled toy car is sent into it. |
| Results | After the car entered the portal, when a three-dimensional object was passed through the car, it showed resistance and was unable to pass through the car. Even though the car looked like it was two-dimensional, it was three-dimensional. |
| Note | When SCP-XXXX-1 decreases a reality warper’s control over their abilities, the reality warper’s abilities become highly unstable. |
