This floor is home to bla bla bla. Why? Because yadda yadda yadda yadda yadda. Also, it has yabber yabber yabber yabber yabber. It also has yeah yeah yeah in it. Nah nah nah.
Floor 1
This floor looks like an ordinary hotel lobby by day. At night the laws of physics become rather malleable.
This floor contains numerous gibberish writings on the walls. They are all written in blood and are from an unknown creature. Nobody had been able to remove them despite several attempts.
This floor is an alien hive. Multiple humans are held captive. Women in particular are the most valuable to the hive since it impregnates them brutally (o.O). Soon after they inflate and explode, scattering alien babies and leaving behind their bloodied remain-- *cough*
There is a privately-owned maternity ward on this floor; the most economically successful in history. It also sports the only alien adoption centre in the world and several marriage councilors, some of whom specialize in trans-galactic couples therapy. Unfortunately for many prospective alien mothers, the wait list is often unbearably long during the bi-millenial tribble migration.
There is an area effect on this floor that can severely affect one's emotion. For example, one can be extremely cheerful and uncaring of life. The next moment, one will become so depressed they will no longer feel like living. Afterwards, they can become so utterly blind with rage that they will cause wanton destruction.
This floor is the home of [Classified] which is just a larger than average [Classified] but with the powers to [Classified] as well as [Classified] and [Classified]. This [Classified] is said to lurk around a tavern in the kingdom of [Classified]. It is very dangerous and should you find it when it's not out travelling, you should run for your life. The floor is mostly [Classified] aside from the [Classified].
This floor acts as the world headquarters of the International Directory of Indexing, Organizing, and Transcribing Syndication, which is currently developing a universal standard of data classification. At the current time, it is still in testing, as evidenced by the incomplete classification of the floor below. Documents pertaining to these tests are classified under part X of index 173B, section 12, of the Official Transcript Summary Pertaining to USDC Classification Testing and Maintenance (fourth edition).
This floor is just a lot of floating islands over an ocean, some say that haunted ships are there... but few people manage to go below the mist between the islands and ocean
This floor holds the Sands of Time, held inside a giant hourglass in the middle of the room. Every 24 hours, it will turn itself upside down in order to measure a new day. Destroying the hourglass will cause time and space to collapse before fixing it back minus you.
