The Realm beyond the 4th wall

Any Character that is able to break the fourth wall can reach at this level of existence the Place where not even the concept of stories can reach. All character that reach this Realm aren't bound by the concept of stories how ever they are still bound to the Evil Entity & The Book. In this realm most Cross over events happen. Since character outside the Teewy verse who can break the fourth wall can reach to this plane of existence and meet with other characters within this or other verses. This is the same reason how 2 Fourth wall breakers from the beyond the 4th wall verse were able to communicate with Rosa another 4th wall breaker from Teewy verse. There are chances that characters on this level of existence can break outside the book it depends if the evil entity allows it. Take note breaking free from the book doesn't mean you're in the real world you will be in a metafictional realm. Any Entity that is equal or superior to the evil entity will not be bound by his authority.

This realm is also called the realm of crossover.

4th wall breakers outside the Teewy verse doens't necessary have to be in this place unless its a cross over event.
