<P> In a final `` Coda '' section , King urges the reader to close the book at this point , consider the story finished with a happy ending , and not venture inside the Tower with Roland . For those who do not heed the warning , the story resumes with Roland stepping into the Dark Tower . He realizes that the Tower is not really made of stone , but a kind of flesh : it is Gan 's physical body . As he climbs the steps , Roland encounters various rooms containing siguls or signs of his past life . When he reaches the top of the Tower , he finds a door marked with his own name and opens it . Roland instantly realizes , to his horror , that he has reached the Tower countless times before . He is forced through the door by the hands of Gan and transported back in time to the Mohaine desert , back to where he was at the beginning of The Dark Tower : The Gunslinger , with no memories of what has just occurred . The only difference is that , this time , Roland possesses the Horn of Eld , which in the previous incarnation he had left lying on the ground after the Battle of Jericho Hill . Roland hears the voice of Gan , whispering that , if he reaches the Tower again , perhaps this time the result will be different ; there may yet be rest . The series ends where it began in the first line of book one : `` The man in black fled across the desert , and the gunslinger followed . '' </P>
