System 7

Description
System 7 is an enormous theatre, with the stage being about 2 square miles in size. The theater also includes 255 seat rows, each row having around 1800 seats. The walls and seats are of a rather dark grey color. Surrounding the seats there is a staircase, allowing access to every single row of seats. There is very relaxing and delicate yet somewhat ominous ambient music, seemingly emanating from the walls of the theatre. A projector located on the very highest part of the theatre constantly displays images of quiet, peaceful landscapes. The device displaying those images is unreachable, but it is speculated it's made out of a metal-like material which is unbreakable. This device is located on the exact middle of the topmost row, simply "sitting" in one of the seats, and there is a 2% chance of it being visible to the eye. Sometimes, a black door with a golden, shining handle will appear on the lower parts of the theatre. Finding this door is extremely rare.

Properties

 * The higher you go into this theatre, the faster time passes and the slower all movements become.
 * Going higher will cause air to become more thinned out and it's much harder to breathe, sometimes even leading to the explorer being asphyxiated because of the lack of oxygen. This is theorized to be because of the presence of silent-form in gaseous form mixed in with the air, with the quantity increasing the higher one goes.
 * Staying in here for over 8 hours without going any higher will cause the music to get more loud, sometimes going to almost unbearable levels of volume. The loudest volume ever measured here has been 164dB. Going higher into the theatre will cause the ambient to be even louder, however the growing presence of silence-form in the air will trick the brain into thinking the place is completely silent.
 * Only one explorer can be found at the time in this level. If any other explorer tries to enter while someone else is on here, every single entrance will be blocked.

Entering
To enter this level, one can wander far enough (around 1 to 2.5 miles) in a pitch-black room in System 1.

Another entrance is entering a dark grey and very small crawlspace inside of a pink house in System 4.

Exiting
To exit, one can open a black door located on the sides of the system, however, it is incredibly difficult to see and changes places randomly and very frantically, so finding it is extremely difficult. Opening this door may take you to System -4 or, very rarely, System 27.
