(I wasn't sure where to put this, here's fine I guess?)
You know how after the credits, there's the scene where Yosafire hears something fall in the garden and decides to check it out?
I've always wondered what fell there.
Personally, I think it might be that girl from Obsolete Dream's prologue (Olivia?)
Reasoning: In that prologue, there was this desolate looking area with poles sticking out in the ground. It looks pretty much the same as that one scene from TGG flashback, along with a girl that looks like the prologue one. That place could be the result of the war between Etihw and Kcalb. (It also brings to mind that one comic in the "various" section.)
The prologue girl states that "I will surely return here...some distant day". The next page has a break, then shows her (maybe) in different clothes in a place with grass, a path, and cherry blossoms falling. If you need proof of cherry petals in TGG, look at the calendar section on DSP's site. For the "distant day" part, assuming the previous place is the war aftermath, then the future version of that place should be the Gray Garden after a very long time.
This is getting long, but that's the basis of my theory.
Any thoughts as to what this could mean? What fell? (it doesn't have to be serious)
After finishing TGG and that short cutscene happened, I assumed that to be the Bonus Room. Well that's because after the cutscene the player can visit the Bonus Room. But of course, it's kinda stupid to think of that given that the entire room fell from the sky XP.
Yours makes a lot more sense tho... However, we can't fully confirm this as of now. A possible reason Mogeko planning to make a prequel and a sequel to TGG is to uncover some mysteries in the original game. We may see who, or what, fell to the flower garden in one of those planned games or, probably, the TGG Remake.
