Dipper POV
Did I just see what I think I saw? I think I just saw a Cyclops. And its coming towards Mabel, Stan, and I. And it has a club. Darn it!
"Kids! Run!" Grunkle Stan yells.
"Mabel, hurry!" I yell to my sister, who is knitting a sweater. I grab the Journal and run. I run into the woods surrounding the Shack and Grunkle Stan quickly follows us.
"Here, take this note and give it to Soos. He'll take you where you'll be safe. And where you'll learn some 'family history,'" he says. "Now, GO!" Mabel and I stand for a moment. She's going to miss her sleepover with Candy and Grenda, and I'll miss my only chance to dance with Wendy.
"No! We have too much we'll lose!" Mabel and I yell at the same time. Weird. Stan picks Mabel and I up and we both struggle to get free. He runs to Soos' grandma's house and hands us the note.
"Go! Now!" Stan says.
"But why!" Mabel says.
"Uhhhhh! Fine! I'm a son of Hades. And your not twins, your triplets! You're a son and daughters of Athena! Now GO!"
Mabel POV
What-for-the-Who-Now!? Aren't Hades and Athena gods from the Greek Mythology thingy we talked about last year? And how can I be related to the goddess of wisdom? I'm so confused…
Dipper POV
What! Stan's related to the god of Death! How the heck does that work! And I'm related to the goddess of wisdom! WTF! And I have ANOTHER sister. Well I might as well listen to Stan…..
? POV
Chiron walked into my cabin, which I dubbed "The Mystery Cabin!"
"Welcome to The Mystery Cabin!" I yell.
He says two words. "Its time."
At first I'm confused but then the fogginess clears and I realize. I'm meeting my sister and brother today. But The Prophecy of Ten stars. Today.
Cliffhanger! I'm SO exited. I am Having a contest on what to name Dipper and Mabel's sister. Comment or PM me about this story and I will put all the names into a hat and choose randomly. If it fits the character, I will use it as her name. Btw, Aphrodite is also in the Pines Family tree. I don't know where, But its there.
