A brown haired girl sighed, walking into the room, "Stop."
Both Dipper and Ford examined the room, looking at the colors draining from the walls. Their eyes eventually gazed upon the girl in the door way. She snapped her fingers, releasing Bill from his restraints. He ran over to her and hugged her.
"Yes... Hi, Father... please stop hugging me..." She grumbled.
He sighed, letting go of her, "Sorry, Princess."
"It's fine, Father," She sighed, looking over at Ford and Dipper.
Cosmo, River, Luna, and Will all ran down to the containment area, all excited to see her.
Will immediately embraced her from behind, surprising her.
"Who are you all? Father, do you know all of them?" She asked, trying to push Will off of her, "Also, can you stop hugging me? You're just as bad as Father is about this."
He smiled, "Yes, I know all of them, don't worry."
"Woah! You have six fingers!" Luna exclaimed, noticing her hand.
She blushed, hiding them in her pants pockets, "It's not that important... their kinda embarrassing..."
"Well, they shouldn't be. It's at least one thing you got from me," Ford spoke up, walking over to her.
She frowned, "Dad..."
"It's alright Aurora, I was embarrassed with my special fingers when I was little too," Ford smiled, showing her his six fingered hands.
She gasped, "Woah. You really DO have six fingers. Fascinating."
"Yes, I thought so too," Ford admitted.
She looked over at him, "So... can you tell me who everyone is?"
"I'll let you figure it out. You're a smart girl, I'm sure you can," He grinned.
She sighed, walking over to Dipper, "Tell me one thing about you."
"Um... I have a Big Dipper constellation on my forehead," Dipper admitted.
She gasped, "Magic potential. Symbols of the night, twins, in the same generation. Mason 'Dipper' and Mabel Pines, the Big Dipper and the Shooting Star. You know what this means, right, Father?"
"Yes, I know. They'll be hunted down as they get older... by the Shadow Men, if I recall correctly," He sighed.
She nodded, "Yes, the Shadow Men. One will die saving the other, and the other will live on to regret it... until their power corrupts them."
"How long until the Shadow Men begin hunting them?" He asked.
She frowned, "Not very long. A few days at least. We need to get working on their magic quickly."
"Of course. After this. There's only four left to go," He admitted.
She sighed, turning to Will, her eyes widening, "You have magic, but... it hasn't reach its fullest potential. I can sense a connection between Father's magic and yours. William Cipher, right?"
"Yeah, that's right. Hello, Aurora Sky," Will smiled.
She nodded, turning to the triplets, "Another connection... between all three of you. Triplets. You're half-bloods, like me. Bridging the connection between the Nightmare and Mortal Realm. One can hear the other side, two can see it. You all have great magic potential, considering that one of your parents is a king, and the other is a rare occurrence that only happens once in a billion years. Even more, the rare occurrence crossing with the zodiac that is destined to destroy our father, causing an even rarer occurrence. You're all very special, Cosmo Galaxy, Lunar Eclipse, and River Tides. Very special indeed. It'll be fascinating to see what you can do."
"Fascinating, indeed. However, we have a time limit now Aurora, and much for them to learn. How can we do this?" He asked.
She smiled, "Simple. Train them in their dreams, that way it won't harm anything if they mess up."
"Exactly."
