Monsters are real, and ghosts are real too. They live inside us, and sometimes, they win.
|~ Stephen King|
The Dark Tower is a dark fantasy series written by Stephen King consisting of 7 books (and a spinoff). The series connects all of his works together. A comic series exists based on the work, as does a recent film that stands as a sequel to the books. A television series tying into the new film is also currently in production.
Power of the Verse
The Dark Tower is an incredibly powerful verse. Each floor of the tower is infinitely greater than the previous. It has every Stephen King character ever written, including several cosmic entities. To top it all off, there exists a race of humans with technology capable of altering the fabric of existence, as well as three beings who transcend the infinite-dimensional multiverse in its entirety. (Two of which are possibly beyond the concept of dimensions as a whole)
