How Much Does It Know? (IT & D.T Spoilers)

[Eric Thompson]

I understand that It/Pennywise believes that the only two powerful beings that exist are Maturin and himself. Having said that, there have been several things in different books that overlap with things that happen in "It". In "Insomnia", the Crimson King calls on the power of what appears to be Deadlights. In the final "Dark Tower" book, Dandelo is a creature very similar to Pennywise. My question is this-does Pennywise/It actually believe that there is no one else other than Maturin and himself? It lives in what is known as the Macroverse, also known as the Todash Space in the "Dark Tower" books. The Crimson King has abilities very similar It. Besides, the Macroverse/Todash Space didn't exist until Gan and the Dark Tower rose from The Prim and created all the universes, meaning Pennywise/It probably didn't exist until after the creation of the Dark Tower. Is he truly unaware of all the other beings and universes?

...that is one of those questions that King has left to the Constant Reader to solve on their own....

Actually I believe this question is answered plain as day in the first It PoV chapter. It muses that It had always thought that the Turtle and Itself (this gets tedious, always capitalizing the "I") were the only two deities, for lack of a better word. Obviously there are other forms of life like humankind but I mean in a nearly-eternal deity sense. From memory, the quote goes something like this:
"Could there be a third? Some Other?
"And could these seven children be agents of that Other?"

Edit: Forgot to mention that It also theorizes that the third Other might have created both Itself and the Turtle. It only becomes aware of the Other after the events of 1958.
