Dimensional Location: The Gravity Falls Universe where Bill Cipher and Lord Voldemort went to Hogwarts as children together.

Location inside Gravity Falls: The Cipher Family Castle

"Pacifica Northwest is our Maid, her own family sold her off to win our support inside the Ministry of Magic." Bill Cipher explained.

"She is under some powerful Mind Control Sorcery." Lord Voldemort pointed out.

"She is one of the Human Soul Symbols on the Hidden Cipher Wheel that we use to Defend Gravity Falls from other dimensions, have a look." Bill Cipher pointed at the picture.

"Llama, Bow Tie, Pine Tree, Shooting Star, Question Mark, Six Fingered Hand, Telepathy Star, Greedy Fish, Stitched Heart, Ice, Gecko, and Glasses." Lord Voldemort studied the 12 Soul Symbols carefully.

"Milo Murphy is the Gecko, his Soul Symbol appeared on the Cipher Wheel the moment he was born. He is inside the Ravenclaw House right now." Bill Cipher explained.

"You want all 12 Soul Symbols under your control?" Lord Voldemort asked curiously.

"Your Soul Symbol is the Stitched Heart and mine is the Bow Tie." Bill Cipher explained.

"Relax, you will be working at my side to Conquer Humanity soon, I'm not going to hurt you." Bill Cipher Reassured Lord Voldemort.

"Your Time Travel Magic was just to get me working for the Cipher Family against whatever this Cipher Wheel is defending you from." Lord Voldemort stated back worriedly.

"The Cipher Family needs you alive to defeat the Time Baby before his Time Travel Army comes here. We use the Cipher Wheel to push him out of our dimension whenever he invades, we can't wait another 30 Years for the New Stitched Heart to replace you." Bill Cipher explained what was going on.

"So you prevented my death because you want me to fight your war for you?" Lord Voldemort asked suspiciously.

"I heard how Harry Potter got you killed, I'm offering you another choice here! Take my deal and together we can Conquer Dimensions without the Time Baby around to stop us!" Bill Cipher proclaimed.
