Confused about SotV lore [Story Spoilers]

[Little John]

After beating Voidling and obtaining a majority of the logs for the DLC, I'm still confused on what's going on.

What is the Voidling?

What is the purpose of the void locus and planetarium? I presume that this is where Mithrix is sent to after the ending of ror2.

Where do we go after we defeat Voidling?

What's with the sudden rapid appearances of different void creatures on the planet?

I'm not really getting what the logs are saying or anything. So if anyone into lore that has a grasp of whats going on, it would be awesome if you could tell me.

Pretty sure it's supposed to be ambiguous, but given Void Fiend's description, it seems like Void entities capture things and turn them into crystal-juice (as said in Acrid's description), and it seems they research and analyze the stuff they capture, or just straight up torture it. Void Barnacle description reveals that SOMETHING in the Void is sentient and can speak/write, my personal bet would be it's Voidling, given it seems to be the one in "charge".

So my guess is, Void entities capture anything they see as valuable and study it, torture it, or both, and possibly use that knowledge to fight "theoretical armies with more resilient hearts and more evasive bodies". It SEEMS that, when they capture you, you are placed in the Simulacrum, where they force you to go through endless scenarios. Planetarium description sees our POV of someone trapped there, and in some iterations, they escape and create a family, a life, just for them to end up back at the Simulacrum, supposedly because the Void creatures got what they wanted from that iteration. I am still missing some logs, especially the Voidling's, so I am still missing info.

As for the other questions? IMO, Voidling seems to be a "child" of the Void, or Void incarnate. I don't know how to explain why I think that, it's just that its name implies that it is either small or unique in the Void. It's the most enormous, powerful entity in the Void we've discovered, but it isn't named "devourer", "destroyer", etc etc, just...Voidling.

My guess is that we didn't come back from the Void once we defeated the Voidling. Jailor's description implies once you reach/are taken to the Void, you only go deeper down, but there's no way to know what truly happened. Called "Fate Unknown" for a reason.

Finally, my bet is that void creatures appear once they sense something grows "out of control". They ONLY show up after a loop, at which point our character has grown strong and is literally massacring thousands, so maybe they pop up when they need to put down a threat.
