The Great Old Ones eventually attempted to topple the Tower as well and replace it with a technological replica under the guidance of Maerlyn by releasing the Prim from large cracks, which then formed in the ground and filled with monstrosities. The Tower was also used to link its own world to others, some of which the Old Ones themselves visited to see horrific events as entertainment, and some to conduct business. But the Old Ones (the civilization of man that preceded the events of the series by several centuries), confident in their technology, replaced the magical beams with ones that could be broken, as they were derived from machines. In its earliest history, the Tower was wholly magical, as were its supports, and was intended to stand forever. Lesser floors in the tower are less than atoms to greater floors. The Rose, however, is not simply a manifestation of the Tower, but a completely separate entity. In other worlds, the Dark Tower can take a number of forms including a tiger and a black house. The tower has a central oriel window which is striated with thirteen different colours which inspired the design of Arthur Eld's crown. The Tower is a six hundred floor spire made of black stone, and the only entrance is a door of ghostwood, with the words 'Unfound' written upon it. Each rose blooms with the light of a thousand suns and each has a beautiful core. This makes sense because the Towers Twinner, The Rose, is surrounded by towers in New York. The Dark Tower is surrounded by a huge field of roses called Can'-Ka No Rey. It is necessary to present a sigul of Arthur Eld in order to enter the Tower and in some legends it is believed the Tower itself gave Arthur Eld his Sandalwood Guns and sword Excalibur. Across the infinite number of worlds, the Tower can only be entered in one: Mid-World. Each portal is protected by a guardian animal. At each end of the Beams, there is a portal, for a total of twelve. It is said to be Gan's body, and is held up by six Beams of great size and length, visible only by their effects on the lands along their lines - such as patterns in the clouds. The Dark Tower is the center of all creation. Size encompasses life, and the Tower encompasses size.” “The greatest mystery the universe offers is not life but size.
