Disclaimers: I do not own Gravity Falls, nor do I own any of the canon characters. All I own, is my OC, Aria. As for every other character, those belong to the amazingly talented Alex Hirsch.

This story is a little, bloody at the beginning, so just warning you now, if you're sensitive to that kind of stuff. Now that that's over with, let us get on with the story!

My name is Aria. I was a normal person, until last year, when I was attacked by a wolf. Ever since then, I have been cursed, to roam the woods alone. It's been months since I've even shown my face in public, not even in my human form. I'm too afraid, that I won't be able to control myself, and maybe even hurt my loved ones.

That's pretty much all you'll need to know about me.

The moon lit up the otherwise clear night sky. My thoughts where clouded by the animal thoughts. I crawled about the forest, searching for pray. That was until I spotted a currently unidentifiable creature in the distance.

I crept up on it, slowly, careful not to chase it away. As it became clearer in my line of sight, I paused. It wasn't an animal, it was a human boy. He had brown hair and pale skin. He wore an orange shirt with a blue vest over it, shorts, and a pair of shoes. Another human, that had resembled the boy, walked up from behind. It was female, with much longer hair. She had on a blue sweater with a leaf on it, a purple skirt, and socks and shoes. I watched from a safe distance.

"I feel like we're being watched, Mabel." The boy said looking around.

The girl looked around as well. "I don't see anything. Besides, who else would be in the woods this late? I think you're just crazy." She said in a mocking tone.

"I'm serious, Mabel, I thought I heard-" He paused. His eyes met with mine.

I started to panic, my animal senses taking over. I didn't know what else to do, it's been so long since I'd seen a human, and I couldn't think. I tackled him, lashing out on him. After a moment, the human in me took control. I paused, looking down, seeing him struggle in pain to escape. 'What have I done?' I thought. My eyes started to water. 'I'm a monster.' I told myself, fleeing from the situation.

"Dipper!" I yelled to my twin who was lying on the ground bloody and wounded. He was un responsive.

I ran over to him, crying. "What the heck was that! I-I need to get you back to the shack." I said to him, lifting him over my back.

A wolf just came out of nowhere and attacked my brother. Based on the creatures I've met in this town before, chances are, that was no regular wolf. I was scared by the thought of it, but it was likely my brother was attacked by a werewolf. This was the forest of Gravity Falls, after all.

We made it to the shack. I carried Dipper upstairs and got some bandages out of the bathroom. I felt better, that it was only a few scratches. Even if that theory I have is true, at least there isn't a chunk of his flesh that was bitten off. I gagged a little at the thought of that, and proceeded to patch up his wounds.

Once he was all bandaged up, I put him on his bed, and let him sleep. Myself on the other hand, couldn't sleep. I watched him, sleep all night, worried.
