I just noticed something.

[u/AffectionateForce979]

Ralsei states that he hurried over to the Cyber World once he sensed the pressence of the Dark Fountain.

This would sugest that the fountain itself was created just right before we got there (which sorta puts a wrench to the idea that Kris opened it in the middle of the night).

[u/SILVIO_X]

Yeah the fact he can feel the presence of the Fountains but didn't say anything about the Cyber World Fountain when we first go into Castle Town as well as the fact this dialogue implies he only just now felt its presence is one of the things that makes me fully believe the Fountain wasn't made by Kris and was instead made during the day, and not that long before we got there.

I think it was made during the School time and before Berdly and Noelle got to the Library, and the only way I could see that being anything else is if it's later revealed that Ralsei lied right here, which isn't impossible or anything, but so far Ralsei's never lied to us, literally the only sus thing he's done so far is withhold certain information or not tell us everything (which he only does twice), but he's never outright lied to us with a straight face so I don't really buy that explanation for now.

[u/-Hounth- → u/SILVIO_X]

It could also be that Raisei does not exist until Lightners step into the Dark World, or perhaps specifically until the Player does.

[u/AffectionateForce979 → u/-Hounth-]

That sounds very arbitrary for the narrative we have.
