The portal closed, and Luz, Amity, Dipper, Stan and Ford were in the Boiling Isles. Amity was comforting Luz.
"Okay, so, I know Amity is from this realm," Ford said. "So if we can gather allies, we can take Bill down."
"Guys, listen, there is a reversal of the incantation that originally summoned him," Dipper said. "We need more people, but we'd need to have him trapped long enough for us to do it. Anyone got any ideas?"
"A binding spell?" Luz said. "But I don't think any of us could get close enough...unless..."
"We lure him away from the city...into the demon realm..." Dipper said. "We can catch him by surprise."
"But what if we fail?" Amity said. "Then he'll just destroy this realm instead!"
"We'll do what we did with the slitherbeast..." Luz said.
"Ice glyph..." Amity's eyes lit up.
"Who's over there?" Someone came over. It was Eda. "Oh hey kiddo! Your little friends told me you'd be away for a while. Oh, and Hunter stopped by. He's outside with King."
"Good, we're gonna need all the help we can get," Luz said.
Anne, Sasha, and Marcy fought alongside Camila. Bill was getting angrier by the second, and unlike normal humans that can easily be disposed of, the witch and the three friends with their Calamity Powers were much more formidable. And now that Dipper, Stan and Ford got away, he was gonna tear the whole planet apart in order to find them.
"Had enough, Bill?" Camila said.
"I'm just getting warmed up!"
Bill launched himself toward Camila and swiped at her, slicing through an illusion. Several more illusions of Camila surrounded Bill.
"Ah, where are you? Reveal yourself!"
"Right here..."
Bill turned to the right, only for his eye to be attacked once again by Camila's staff.
"Goddammit!" His vision was blurry, but the attack didn't take out his eye.
Sasha powered up her sword using her Calamity Powers and sliced through Bill's side. Anne and Marcy slammed into him, causing him to fall over into a building. Part of the building started to collapse on top of him. Camila and Anne rushed around to get people out safely.
"Alright, that's it!" Bill punched the ground, causing it to cave in around Camila. She got out of the way before it collapsed, but Sasha fell in, holding onto the edge.
"Sasha! I got you!" Anne went to grab Sasha, but Bill hit Anne across the street into a flower shop. She was knocked out.
"Anne!" Marcy flew over to help Anne. Sasha fell down and Camila went in after her. Camila grabbed Sasha and flew up with her staff, dropping her off near Anne and Marcy. Camila flew back towards Bill. She landed and cast fire blasts at his eye, blinding him.
The portal opened back up. Luz waved towards her mom.
"Mom, follow me!"
"Luz?"
"Just trust me..."
Okay mija, I trust you...
Camila flew towards the portal. Marcy got Anne back up and joined up with Sasha. They followed Bill into the portal. Eda made the portal larger so Bill could fit through.
"Oh no you don't! I can smell you! You won't get away!"
"Over here!" Eda said in a taunting voice.
Bill ran towards the voice, enraged, not realizing they were setting a trap.
Luz was waiting to activate the ice glyph. Bill came through, Luz touched the glyph, and Bill slid down into a giant hole that was dug up. Amity performed the binding spell on him.
"Wait, what? I can't move! What is this?"
Hunter appeared by Eda, and together with Luz, Amity, Anne, Sasha, Marcy, Dipper, Stan and Ford, they read from the book and chanted the incantations to seal Bill away.
"Unde venisti, et manebimus, item completum usque ad vos!"
"What? Nooo!"
Bill struggled to move, but it was in vain. He began to slowly vanish while he desperately tried to escape.
"I will return! And next time, I'll have all your heads on a platter! Noooooooo!!!!!"
Bill screamed until he vanished completely.
He was gone.
"Mom!" Luz ran to hug her mother.
"I have...a lot of explaining to do..." Camila looked saddened.
"Why did you never tell me you were a witch?" Luz asked. "That you...were Azura?"
"I'm...not Azura...that was...my mother..."
"What?" Luz never knew her grandmother. Her mom never talked about her in any way.
"I was born in the human realm...my mom met my dad when she was in the Dominican Republic...and...they had me...so, I'm a half witch...my mom gave me her staff before she died...told me to take good care of it..."
"Why did you never tell me any of this?" Luz asked.
"I didn't want you involved in all that! I gave up magic...a long time ago...I swore I would give you a normal life...but now I realize...you need to form your own path in life..."
"But why can't I do magic on my own?"
"I can't do magic on my own either. We're powerless witches, descendants of the first witches on the Boiling Isles. Early witches relied on the natural magic around them..."
"Powerless...witch?" Luz turned her head to Hunter. Could we be...related somehow?
"I can't keep you from doing what you want to do...so if you wanna move to the Boiling Isles one of these days when you're old enough, that's fine with me..."
"You...you mean it?"
"You have real friends there...just make sure to always call me..."
"I will, mamá..."
King walked up to Luz.
"Is it just me, or did that giant triangle sound a lot like me?"
