Description: SCP-XXXX is a 5 story building, plain white. There is only one entrance, the front door.
The first floor has nothing, except for a light breeze. Its unknown where it originates. When night vision goggles are put on, everything around will appear burning and what the person sees is different for every person. It is assumed to be their worst fear. This is when the anomalous effects start, the "vision" the person sees can and will hurt or kill them. If the goggles are taken off, its just a calming light breeze.
The second floor has a librarian (SCP-XXXX-1) who is extremely kind, and offers a book to read. She sits at a desk in the middle of the room with fancy stairs leading upward. No anomalous effects are noted until said person comes back.
On the third floor, there is the desire of the person who looks. It appears to be a memetic effect, because the test footage showed a spiked wall, while Class D described it as something they had wanted their whole life (Freedom, Death, Friend, Etc.). If resisted, the wall looks like a wall of spikes, if not, the people who are looking begin to move toward it until they are impaled.
The fourth floor has 1 chair in the middle (SCP-XXXX-2). No damage is took when the chair is harmed. The anomalous effects start when sat on. the person who sat will become very tired. Their muscles start to drain and they become very weak. the wall opens up and a figure comes out (SCP-XXXX-2-A). SCP-XXXX-2-A is a 5 foot tall humanoid, appearing to be completely grey with no facial features. SCP-XXXX-2-A begins to [REDACTED] the person and implants a little metal ball into their spine. This causes transformation into SCP-XXXX-2-A-1. The metal ball melts onto their spine, then covers their body. All instance of SCP-XXXX-2-A-1 have no vital signs, and must be terminated immediately. If a human is to come into contact with an instance of SCP-XXXX-2-A-1, It will transform the human the same way they were transformed.
The fifth floor is normal, until someone steps onto the middle. Tentacles (SCP-XXXX-3) rise out of the ground and try to grab said person. If that person is grabbed, the tentacles drag them through the ground into a pocket dimension, where its full form is unveiled. SCP-XXXX-3 looks like a octopus. When shot, SCP-XXXX-3 screeches, and more tentacles come out. If shooting continues, the whole thing comes out and goes on a rampage breaking through buildings and targeting civilians. The only weapon proven effective on SCP-XXXX-3 is any type of fire/flamethrower which dries it out. When killed, another instance of SCP-XXXX-3 takes its place, back in the pocket dimension.
SCP-XXXX-1 has exited the building multiple times, and is allowed to. Anything else exiting the building is to be terminated. If anybody enters SCP-XXXX, and goes past the second floor, they are assumed as KIA and no rescue attempts will be made.
If a instance of SCP-XXXX-2-A-1 is not terminated, it will attempt to exit the building and "infect" others.
