Pennywise/Crimson King connection?

I was struggling a bit with the concept of this creature the other day, ended up contradicting myself a lot because I'd forgotten a lot about the Dark Tower. I'm still pretty sure about some of what I said, but upon organizing my thoughts, I came across a theory that relates to the Dark Tower.
I remember reading somewhere that IT and The Crimson King, while not the same entity, are both essential oppositions to order within the universe. As in, they both bring chaos, while The Turtle, as well as the other beam guardians, bring the opposite.

That would make IT one of the demon elementals, assigned to the Outer Beam. Thus, the Turtle is in alliance with the "White." IT, while still assumed to be a cosmic entity, would be one step below the Crimson King (as far as servitude, at the very least), but still extremely powerful. If IT is more powerful than the Crimson King, I suppose its allegiance would originate from CK's goal involving the Prim, etc. CK has a bit more flexibility.

This would account for Insomnia's

"Deadlights" sighting. If IT were to be assumed in "cahoots" with the Crimson King, IT may have assisted him near the end of the novel by snatching him out of Derry. I assumed, from the way I was interpreting that particular passage, that the deadlights were not coming directly from the Crimson King, but instead from the dimensional tear above him.

As Robert Gray stated, IT's line of thinking was completely different than CK's - thus, what would remain unexplained within this line of reasoning is the fact that IT was not aware of any other cosmic entity besides itself and the Turtle. I'm not going to venture a guess at why this is (in relation to this theory), since the concept of IT being the beams' antithesis to the Turtle is only speculation to begin with.

Um, I may be wrong, but didn't the Crimson King make a reference to It at some point? I read that on Wikipedia, and I think it was for a book in the DT series that I haven't gotten to yet.

I know this thread is quite old by the looks of it, but I found it on google and found fascinating. I personally am very disappointed that IT didn't make an appearance e in the Dark Tower series. There's indications that IT survived the Loosers Club in Dreamcatcher and Tommyknockers and this year I was hoping for a sequel novel perhaps, something explaining the Deadlight connection with certain villainous creatures in the King universe.

I LOVE the idea that the CK and other deadlight related entities are spiderlings that scuttled away after the looser's confrontation with IT, and maybe the surviving Pennywise is meerly a spiderling taking on the pesona of it's mother.

I hope that the deadlights return to earth possibly causing another cataclysmic event in 2012 like when it first arrived. Or that IT awakes as 2012 is around about the time IT wakes and feeds again. Or at least King explains the relationship between CK and IT in a novel soon.

in the comics sk reveals that the king is the son of arther eld (my spelling sucks) and a creature from the outside of our universe (ie it who was female). and in the second part of it the adults find it's eggs and the architech sayes he thinks he killed them all. so i say that there was one surviving egg and that became the crimson king who then grew up in dairy or returned after he was older to do the stuff in insomnia.
