Hi, Everyone! This is an idea for a SCP that I had a while ago and decided to try and write it down. This is my first attempt at creating a SCP, so any hints and criticism is very welcome. Grammar corrections are also accepted since I'm not exactly good at it. I will finish this (specially the addendums) when I get more time, but I'd love to see you guys' opinions.
Item #: SCP-XXXX
Object Class: Thaumiel
Special Containment Procedure: SCP-XXXX is located in ███ ████████████ casino, currently in the possession of the Foundation. Due to its amnesia-inducing properties, the inconceivable high cost of rent and the Foundation's control of the location, it is considered a secure SCP.
Description: . SCP-XXXX consists of the last 3 floors of the casino, accessible only by elevator. These three floors are the Cocktail Lounge, the Presidential Suite and the Penthouse, all perfectly clean and furnished. How SCP-XXXX cleans and organizes itself is unknown. See Addendum XXXX-A to F for the effects of SCP-XXXX in living beings.
While the Cocktail Lounge and Presidential Suite present no anomaly besides the induced memory loss, the Penthouse floor has a Commodore PET 4016 computer located in a small desk in the left-most room of the floor that when accessed, shows only the word "Expand". When clicked the computer will shut off, and the concrete wall will slide open, revealing a completely empty 7,2 m x 6 m x 4 m room.
Any object – living or not – that is left inside the room when closed will be fully boxed and placed on the best fitting corner of the room. If none is available due to other objects in the room, the new box will be placed near another object where it best fits. On top if it's a smaller object, below if it's a bigger object or on the sides if it's too big to be placed on top or below. No objects are placed in the middle of the room, and for this reason the wall at the end of the room is always accessible.
If the room runs out of space for storing objects within it, another door will appear on the wall at the end of the room, which can be opened to reveal another room of the exact proportions. So far, the foundation has created █ rooms.
Due to the amnesiac effects and the capacities of SCP-XXXX, the foundation has been using this SCP as storage for other SCPs, specially for Safe and Euclid classes.
Addendum XXXX-A: On ██/██/19██, after partying for approximately six hours (From ██:36 to ██:11) a man by the name of Vincent
