Well, she did write the instructions for John to retcon the timeline which resulted in an infinitely better Alpha timeline where everyone is happy so I would say that’s pretty important. 

He talks about his problems with the dreambubbles and doomed timelines here. 

It’s fully evolved, the Mobius Net is needed to stop the Battlefield from being destroyed by the Reckoning.  There will be no Reckoning in the Alpha session so the Net isn’t needed.

No, Roxy buried her on LoWaS

Aranea speaks about their Empress here.  She never mentions that it was Feferi but we can tell it was her pre-scratch counterpart based the fact that Culling in Beforan society means what Feferi wanted to change it to on Alternia when she was empress.

Okay, this is kinda difficult to explain, so there was blind sollux and a ghost sollux and when blind Sollux died the two kind of merged into a half-ghost Sollux that was blind in one eye. And then pre-retcon the ghost was sucked out to make Erisol so then he was 100% alive but entirely blind. 

We don’t actually know how that works, it probably has something to do with him having two dreamselves.

It’s just a net, probably used as a defense against the Reckoning to hold off meteors from hitting the actual Battlefield.

Roxy buried GameOver!Rose on Lowas and Jaspersprite dug her up and prototyped her in Roxy’s kernelsprite. 

Have you forgotten that I’m actually literally Caliborn? ~Mod T
