The door of SCP-XXXX now, this picture was taken in the High-Temperature-Erase Unit
Special Containment Procedures: The SCP-XXXX is now contained at Site-19, and the room it replaced now was a SCP Foundation Class D's bedroom, with 50 meters long, 30 meters wide and 3 meters high. Its Containment Procedures is to set up electromagnetic blockade in its outside, temporarily stop its movement. SCP - XXXX in █████-███-███ moved to the Site - 19 and replaced by a male toilet, then in █████-███-███ moved to a Class-D dormitory. The toilet has been sealed off by the foundation to prevent any accidents. As the room was occupied by SCP-XXXX, the Class D personnel who lived in the room had to change their dormitory. After XXXX-alpha event, a room must be set up at the door of SCP-XXXX to perform High-Temperature-Erasers Unit, and at least two experimenters should monitor SCP-XXXX continuously to judge whether SCP-XXXX-2 is generated or not, and three armed men stood guard with flamethrowers to prevent the SCP-XXXX-2 from escaping.
Description:The SCP-XXXX has been described as an entity similar to a normal room, and seen from the inside the SCP-XXXX is about 20 meters long, 26 meters wide, and has an almost infinite height. It can teleport to and replace any normal room, and after the SCP-XXXX leaves, the rooms it occupied will be restored to the original room. When SCP-XXXX moves and replaces a normal room, if there is no one in the room, there will be no change in appearance, and the interior will be transformed into SCP-XXXX interior in an unknown way. If there are people in the room, they will be sent to a random location. When SCP-XXXX moved to the Class-D dormitory of Site-19, a staff member in the dormitory at that time disappeared directly, and appeared in the attic of a residential house in Toronto. Three days later, He was sent back by the Canadian SCP Branch, and they gave the owner of the house a Class-B Amnestic. The SCP-XXXX looks no different from the room it replaces, but no matter how big the room it replaced, the interior of the SCP-XXXX remains forever 20 meters long, 26 meters wide, and almost infinite height. The walls of the SCP-XXXX are made of a hitherto unknown and indestructible bluish-grey material, none of the existing durometers can be measured. If a human stays within the SCP-XXXX for more than about 100 seconds, according to the report of the Class-D, the top of the SCP-XXXX suddenly lights up with a beam of about 50,000 lumens and the walls begin to peel off and turn to ash(We also wondered why its walls would never be used up, since the amount of ash used to make an SCP-XXXX-2 is enormous.). When the ash accumulates to a certain extent (usually taking 3-5 minutes), they start to gather and result in the appearance of a humanoid creature made up of these ashes, which we named SCP-XXXX-2, which was described as a black humanoid creature between about 3 feet and 4 feet tall, with no features, it can take any shape it wants. Its density is unknown, weight is about 70 kilograms to 130 kilograms. This humanoid creature is hostile to any creature within the SCP-XXXX, usually by enveloping the target's head and choking it to death. After all of its targets die, it will try to leave the SCP-6000 and find new targets. Any attempt to move the SCP-XXXX-2 out of the SCP-XXXX has failed, but we can roughly judge that it does not have the intelligence. When there're no humans in the SCP-XXXX, the walls will also slowly peel off to form SCP-XXXX-2, but this process that typically takes 12-15 hours. When SCP-XXXX-2 is generated when there're no target in the SCP-XXXX, it will attempt to leave SCP-XXXX and slaughter any creatures it encounters along the way. The only effective suppression method is high temperature. When SCP-XXXX-2 is destroyed, the ingredients of its body-the wall ash of SCP-XXXX will instantly be vaporized, leaving no trace.
