Last night I was talking abt rain world bullshit with my friend bits again and I realized the answer to a question I'd been wondering for months now- Whats the Connection Between UE and OTR?
Well, Outer Rim represents the crumbling ideals and fears of the ancients, their concerns that lead them to build tons of iterators and reform the entire landscape, only to leave it behind and let it rot. It represents the futility of trying to find the solution, literally trying to catch the stars
UE is a deeper meaning of this rot and fear, the inverse of the void sea where you're left with absolutely nothing and which exists without purpose. The endless stretching iterations that just lead to nothing, as the iterators slowly go mad at their typewriters
Prince does not do anything for you. Unlike Five Pebbles, who gifts you enlightenment like its nothing and then asks you to never return, Prince wants you to return, yet he offers nothing.
The Rot Worm is much the same, obviously interested in you, but giving you nothing at all. Just as alien and beyond you as the Void Worms are, you're not able to connect with it. And it does nothing.
I said before but the connection between iterators and void worms is obvious, as these are beings that help YOU reach enlightenment, but Watcher essentially has to "teach" Prince
I think Watcher and its personal connection to OTR and UE (and by extension Spinning Top as well) is that ascension is a personal journey, not one that can be given to you, but one you don't have to take alone
