They're one of my favorites slugcats when it comes to design, gameplay and vibe but I've very vividly heard about their lore and am very curious and don't care much for spoilers, could anyone either DM me or comment on here with some explanations? For instance;

How does it end?

What happens to five pebbles in the long run since it pretty much sounds like he's a bad dude or something.

What's spearmaster supposed to be doing in that area, I know he's supposedly a messenger who's owned like a pet by some iterator who I -think- isn't fond of five pebbles due to him being a bad person for almost killing moon. To be clear I only vividly know bits about the iterator lore in rain world, I mainly play it for the more creature side of the game, see me as just a zoologist who's curious about the stuff that happens to be going on amongst all the cool creature stuff
