A/N: I am very excited to be making the sequel to A World Away. I didn't want to spoil anything but I kind of have to, as I will absolutely be playing with my favorite Gravity Falls AU. It's going to be my own twisted version, so don't worry about originality. You'll be able to guess pretty quickly as to what it is. If you haven't read my first story yet, you are going to want to, because otherwise you will have no idea what is happening.

Disclaimer: I don't own Gravity Falls, because if I did, it would still be running.

And Dipcifica probably would've been confirmed.

Anyways….

Chapter 1: Mistakes

-Rana POV-

It'd been a year since I'd first left Gravity Falls. At least I could catch them for the last week or so of summer. I was excited to show Mabel and Pacifica all of the souvenirs I had found in all of the other worlds I'd been to. I had gone to other worlds before, of course, but I was always with the agency then. Now I was alone, and I didn't have to follow orders. I could take what I wanted from other worlds, within reason. It's not like I was going to steal things – fine – valuable things.

I was also wondering how everyone would react to my new – um – look. It had been a whole year, so I'd changed a little. My hair was now cut right below the chin. I had also taken to wearing a lot of black in the past year of traveling. There was a lot of running involved. Today I was wearing a long-sleeved black T-shirt with black leggings and a pair of black sneakers. I needed to be able to move quickly. The other thing I was hoping that at least the twins wouldn't notice was the necklace I was wearing that featured the prison box with my sister inside.

I wasn't happy about that little bit, but it was necessary. She was a danger to everyone and everything I cared about, and this was the only way to keep her from hurting anyone.

I looked down at the necklace. There was an odd spiral pattern on each side. I grabbed a small black backpack with a large blue pine tree surrounded by an even larger white whole note. I had made it when I first returned to my home world in memory of everything I'd left behind. But now I was going back.

I slipped on a black hoodie, pulled the hood over my head, and grabbed the portal remote. Before pressing the correct buttons to send me back to Gravity Falls, I took one last look at my apartment. My bed looked completely abandoned, covered in dust and stripped of all the sheets and blankets and pillows. The posters for all of the different bands that Serena obsessed over were everywhere, covering nearly every inch of our walls.

Then I looked over to Serena's bed. The pillowcases were dotted with little skull designs, and the sheets were the exact same pattern. And sitting on top of her bed was Serena herself, concern in her eyes.

"Rana, are you sure you don't want me to come with you?"

I sighed. I really would've loved for her to come with me. She's my best friend after all. But I needed to go alone. It had been such a long time since I'd seen all my friends in Gravity Falls, and I wasn't sure how everyone would react to bringing my best friend along. I wanted to focus on having an incredible last few days of summer with them. No distractions.

But there was one thing I could do. I pulled out my cell phone and gestured for Serena to take out hers. She reluctantly pulled it out and placed it in my hand. Within seconds a blue fire erupted from my hands and both of our phones. As soon as the fire disappeared, I handed Serena's phone back to her. When her only response was a confused stare, I explained what I had just done.

"There. Now if I need backup, I just need to say it and my phone will send a distress signal to yours. Got it?"

She nodded. But then she asked the most pointless question I'd heard in my life.

"Couldn't you just call?"

I sighed before I gave my annoyed answer.

"Possibly, but there is a strong possibility that the barrier between the two worlds would stop a normal phone call."

Then I smirked.

"Plus, who would want to have to dial?"

We both smiled and shared a quick hug before we said our goodbyes.

"I'll miss you, Rana. But I hope you have fun. Say hi to everyone for me! And please don't almost get yourself killed this time."

The smiles that had vanished completely returned as I said my last few words before returning to Gravity Falls.

"No promises. But I'll try. See you in a week or so."

"See you."

With that, I pulled out the remote and I pressed the correct combination of buttons. Suddenly my surroundings transformed. I was no longer in my bedroom, but in the middle of the clearing where I killed my brother. There was a fresh summer breeze and the trees and the flowers surrounding me created a breathtaking view, but the sight of this clearing still brought an uneasy feeling.

The tree and the music note were still there, but the half note had become a whole. Everything that had happened there was racing through my head at a million miles a minute.

First it was finding my powers. Then it was when we discovered the prophecy. Then it was the fight where everyone thought I died. Finally as I started remembering the final battle, I burst out of the clearing towards the Mystery Shack.

I was so focused on getting away from that clearing that I barely noticed when I'd finally reached the front door to the Mystery Shack. When I finally looked up to see the wooden door to the Shack I had stayed in the summer before, I couldn't help but smile. Inside I could hear movement so I knew they were inside. In fact, the Shack should've been open. But when I tried to push the door open I found that it was locked.

That was quite odd for the Mystery Shack. It should've been open by now. But it wasn't. I was curious as to why they would have the door locked, but I knocked anyway. I needed to get inside even more now, because something had to be wrong.

The thing that really left me in a panic, though, is what happened when I knocked on the door. I heard lots of footsteps and then everything went silent. Okay. Now I knew something serious was going on.

"Dipper? Mabel? It's me, Rana! Come on, let me in!"

There was no response. Not even a whisper, or even more footsteps. There was only silence.

"Alright. I'm teleporting in. You can't keep me out forever."

In seconds a blue fire surrounded me, and less than a second later, I was inside the Shack. Nobody was in sight. I decided to look around. They had to be inside there somewhere. First I checked the attic. They were nowhere to be seen. I checked the whole place before I realized the most likely place that they went.

I headed towards the vending machine. As I punched in the password, I heard footsteps behind me. I chased the sound of footsteps to the door, which was wide open. Just as the door came into my view, I saw an odd-looking silhouette in the doorway. It turned towards me for a fraction of a second, but then it turned away and ran into the woods.

Whatever that thing was, it seemed to know me, and it probably did something to the Pines. That was all I needed to know for me to chase it. It was unnaturally fast, but I had magic on my side. I tried chasing it on foot for a while, but it didn't take me long to realize it would be impossible.

A blue fire surrounded me and soon I was directly in front of the creature. It was half human, half animal. It was so dark in this part of the forest that I couldn't tell exactly what kind of animal or what its face actually looked like.

But when it spoke, chills ran through my spine. And I knew I had made a mistake.

"Don't you dare come near me!"

It started to back away. I couldn't stop it. I couldn't even move.

Oh no.

A/N: This was such a fun story to make. I am so excited for all of the new adventures that Rana is going to get into. Can you tell what AU it is yet? Have you figured out who the mysterious silhouette is? Tell me what you think in the reviews and favorite and follow to find out all of the answers!

Riddle: Killed her brother. Hurt her friends. The monster inside her brought love to an end.
