One thing I really love about Rain World's worldbuilding is how fresh of a take on the Advanced Precursor trope it has, just in the sense that there's a very real sense that the Benefactors were. just people.
Like, in broad strokes they are the Advanced Precursor trope, a bunch of stylish jerks that were there, built some cool ruins, fucked shit up, and are Gone now. But the way they go about it is refreshingly human. Like, ascending to a higher plane of existence is a classic thing for precursors to do but the benefactors give a real sense of what it would be like for a society to do that. Not just in the logistics but in the circumstances that would cause it.
It helps a lot that the remains they left behind are so telling about who they were. There's an endearing mundanity to a lot of the pearls that gives a sense that they were just people in the end, and we don't really get that stuff with other Advanced Precursors in media. I really can't imagine like, a chozo working minimum wage.

I know that this is not possible, but i just want them to be happy kids... And playing children games... Am i asking too much?
me: i wanna talk about my ocs
someone: ok tell me about your ocs
me, suddenly convinced that every single thing about my ocs is stupid and cringy and probably offensive: i. have them
had a silly thought/headcanon about rain world as implied by The Watcher (spoilers for the main ending!)
so we've seen that the ancients all had pretty long names (like Six Grains of Gravel, Mountains Abound), and while the iterators follow the same general naming scheme, they're much shorter (Five Pebbles/Unparalleled Innocence/etc)
assuming Spinning Top is her canon name and not just a nickname for the code, to me that implies the ancients' children were given shorter childhood names, and received a full name once they reached adulthood—especially since Spinning Top seems to be named after her favourite toy.
the name Spinning Top also lines up with the short naming scheme of the iterators. in vanilla, there's already reference to the fact that the ancients were the iterators' parents, even if only symbolically. based on these things, it can be assumed that the iterators were named as if they were ancient children!
i always adhered to the headcanon that the iterators' puppets were child/doll-sized and that slugcats were small, which is somewhat reinforced in the Watcher's main ending; i still interpret the room sizes as being exaggerated, and also that the shadows are being stretched by the direction of the lighting. i also uncharitably thought this was deliberate so that the ancients could feel powerful next to their creations, but now i think it's more likely it was done out of fondness.
it could also be symbolic, to show how the iterators don't age the same way fully organic beings do, and they've been stuck with their Big Task for all eternity... but that's reading into things.
