Summary
Reality and Fiction. One that resides in our world and the other that we create. Now, what if I tell you that there’s a universe where two exist in the same world? In a world where both real people and fictional characters live on the same planet, what do you think would happen? Would it be peace, chaos, or something much deeper? Let’s take a look at one of them to see how they live in such a world like this and find out for ourselves!
If you want to adapt this into a comic, animation, or whatever you want, then you can do it without my permission. Just don't forget to credit me as the original creator of the AU.

**CHAPTER 5 WEIRD ROUTE SPOILERS AHEAD**
Susie was the one who found them. Kris had been holding Noelle’s chin up, out of the water, and Susie would always swear Noelle was still alive for a heartbeat after bringing the duo ashore. A heartbeat, however, is only that. Days later, an investigative team arrive at Hometown and rub salt in the wound, claiming that all signs point to Kris being the perpetrator of this murder-suicide.
Although the lie was at first met with disbelief, it gradually began to infect the thoughts of Hometown’s residents like a plague. Susie can’t bring either of her companions back, but she can at least wipe the dust from Kris’ name, can’t she?

Summary
In search of a missing relative near Mt. Ebott, Frisk falls in the Underground. What should have been a short stay soon turns into a perilous journey through places far different from what they expected.
Note: This story is my personal interpretation of Storyshift. It includes some heavy headcanons that diverge from both the Pre-Boot and Reboot versions of Storyshift. I am using this AU as a creative sandbox, so please keep that in mind while reading!
