A part of me wants to post what I do have of MemoryFalls on tumblr already, though fair warning most of it is either unfinished or being redrawn and redone. I'll share a small, basic idea of it though:

[ Thanks to @tozxrvo-huskiel for helping me with this piece ]

MemoryFalls is centered around Fiddleford's perspective of an Evil Ford AU. In this Alternate Timeline, Stanford betrays everyone when they needed him most and joins Bill's side. Bill wins, sending the universe into a chaotic Weirdmageddon.

Despite being evil however, Stanford still shows that he cares deeply for his friends and family. To the point he literally has his heart on his sleeves (golden pins on his cuffs, one of a pinetree and one of a shootingstar. He's even stolen Stan's suit.) His design is being reworked, so lack of proper Evil Stanford art right now. Though this is his OLD DESIGN:

As for Fiddleford, his body was turned 30 years younger because that was how Stanford last physically saw him. However, Fiddleford himself still has his same old mind. He's not the same as Stanford remembers him as entirely, but he holds onto that nostalgia. He has missed Fiddleford greatly, but also gained an obsession.

Stanford pretty much makes Fiddleford live with him now... but Bill isn't too happy about the new resident inside the Fearamid.

As for Mabel, Dipper, and Stan. They start off in their own separate prison bubbles. Mabel especially is stuck the longest.
