It was a surprisingly warm day for winter in Gravity Falls. Dipper was going about the usual routine: Get up, go to the bathroom, make breakfast, read journal, etc.

But Dipper couldn't shake the feeling that something was wrong. He was reading the invisible ink writing when he discovered (in the journal) a secret portal, to unknown lands. "Hey Mabel! Come check this out, I found something!" he shouted downstairs.

Mabel's POV

He called me upstairs, and that he had found something. "Coming!" I said, swiftly moving up the stairs to the attic. I burst through the door. It must've scared him to another realm, he just sat there looking at the ceiling.

I followed his gaze. There was a gaping hole, no… not a hole… more like a portal. Suddenly, a bright blue sky appeared, Dipper and I were no longer in the shack. I don't know where we are. I look up and see three large figures in the sky. They land right in front of me, nearly crushing me and my unconscious twin.
