My take on it–although always shifting–is this:
The entire universe consists of an infinite number of realities–or “levels” on the tower. The tower serves as the lynch pin, the common axle upon which the wheel of each reality spins. Things happening in one reality can influence or leak over into another, especially in Mid-World because of the degradation, referred to in the common saying “The world is moving on”. The “Old Ones” who installed the beams and built the guardians to protect them were probably a more advanced version of our society–and things like the Citgo oil fields and the train cars suggest that their development closely mirrored our own. In The Waste Lands, however, we see the remnants of a land blasted by some type of nuclear accident or conflict–populated by mutants and monsters. It was after this destruction, and most likely similar occurances throughout Roland’s world, that the Old ways were forgotten and the society gradually degraded into the “western-ish” version we see Roland and his ka-tet travelling through.
Further complicating things is the existence of the thinnies, and the portals that sometimes open between separate realities like the ones that Eddie, Susannah, and Jake came through. This leads to things like “Hey Jude” being a well known tune even over in Mid-World where The Beatles most likely never played a gig. Also, if you’ll remember, Jonas–among others–seems to have the ability to either create these portals or simply to find them, meaning he can travel in and out of his own world as well as others. Marten–the wizard with whom Roland’s mother was having an affair–seems to be Randall Flagg, who appeared in The Stand and tried to take advantage of the plague in that reality and take power. He failed, but we see that he’s far from dead, simply moving about in other worlds and doing the same thing. What his motives are is anyone’s guess. He seems to serve the Crimson King, at least in some way, but I think his main objective is simply to spread chaos. For in chaos he can have the most control.
I agree that Wizard and Glass is the least zippy of the stories so far. It’s mainly background characterization for Roland, and serves to show how he became the man he is as well as filling in a few gaps about the recent history of Mid-World. Keep the faith though, the last thirty pages will blow you away–
When they come upon the Emerald Palace in the city of Oz, I was floored. I still haven’t decided if, in that reality, Oz was a true place; one that Frank Baum may have somehow visited, returned from, and written about in our world. Or, if Flagg simply plucked the story from the traveler’s collective consciousness and created the images they saw to throw them off balance and confuse them.
As to King finishing the story–I’ve actually heard that book five, The Wolves of Calla (?) is already completed. However, he’s sitting on it until the last two are also done so that they can be released bam, bam, bam–like the Rings trilogy has been. I also suspect he’s doing this so that he doesn’t put something down as canon that he’d later have to work around in the final book after changing his mind about some detail or the direction he’d like to go. This way he can finish the story, and tweak what needs tweaked before anyone is the wiser. Still though, there’s some days I’d like to visit his house and slap him upside the head for keeping me in suspense this long. I WANT MY D.T.V!!!
