My personal theory ( antil Al explains it half-right, or Vriska explains it half-wrong, and then it becomes Headcanon) is that it's a game construct,
like god tier obviously, but one that sorta mimics A Post Game situation,
like you god tier'd and you got your reward and you expend a hole lota time in there and because it's been like years and you have grown as Pearson significantly, you can go away and do something else,
explore old and new and waht not. hence Vriska senior(senior for reals now) having a literal portal in the crown situation.
What do you guys think?
I personally think that twarting Rose's vision is a (boosted) Light aspect thing separate from the hell portal, but would love to hear more takes.
Ygnore tipos IS like a beet or somethyng!!!!!!! :3
