Fourth wall

The fourth wall is the imaginary "wall" at the front of the stage in a traditional three-walled box set in a proscenium theater, through which the audience sees the action in the world of the play. When a character makes direct contact to the audience from a film or television program or references his or her status of being in one, it is called "breaking the fourth wall."

In the series, it is depicted as a literal brick wall with a green glowing 4 on it, floating in the realm of Metaspace. Its purpose is to separate reality from fiction, as well as making sure that stories progress logically.

Should someone break the 4th wall, colossal catastrophes would occur. Not only would Reality and Fiction blur together, stories would no longer make any sense and random, chaotic events would occur. These catastrophes are displayed as characters swapping personalities, memes and random stuff popping out of nowhere, random background music playing (mostly 2204355), and the world glitching, not to mention the characters occasionally appearing as wireframes for a second. Thankfully, the wall can regenerate itself. This version of the wall was inspired by the one from the CP Fanon wiki.
