A/N: There is a slight TRIGGER WARNING for the last part of the chapter. I'm not sure what to call it, unfortunately, so just beware when reading it. It's nothing physical, so don't worry about that.
There was another Big House meeting. Tears stained Nico's cheeks. Thalia and Clarisse looked devastated.
"I'm going to find her." Nico vowed, his voice hoarse.
"We'll look for her too." Thalia promised, speaking for the Hunters. "Where can we find Khione, Chiron? Where would she have taken Elsa?" Chiron looked tired and worried.
"What do know is that Khione is the child of Boreas, the god of the northern wind." He said slowly. "He resides in Quebec."
"But where in Quebec?" Thalia asked. "The province is fucking huge." She looked around at some shocked faces at her language. "Sorry," She sighed. "Rough day." There were murmurs of agreement. Nico scowled. Nobody had it as bad as he did. None of them understood. They didn't understand what it was like to have the only true friend you've ever had—essentially your sister—kidnapped right in front of your eyes, and taken away by a goddess who had been out to get both of you for a while, and whom you had forgotten about.
"The city inside the province." Chiron clarified.
"Well, that does narrow it down." Thalia sighed. "But what to do when we actually find Elsa…"
"You can't do anything." Nico mumbled. "Khione is too dangerous. She—she freezes people's heads, sending them into a deep coma where they can be only be saved by an act of true love. Elsa nearly died in one of those, and she's Khione's daughter. Anyway, that's only if Khione's being nice. She freezes hearts too. She froze both mine and Elsa's hearts. Those too can only be thawed by true love, but this is more circumstantial. Khione… She's bad news." He swallowed. "She-She has no mercy. Don't go after Elsa unless you have a god or goddess on your side. Neither of us could take her. Elsa is one of the most powerful demigods I've ever seen—and as she ages, that power will only grow—but she can't defeat Khione."
"What are you talking about, Nico?" Thalia snapped. "We all know you're going after her. Alone." She was right, and Nico didn't even try to deny it.
"Well, Thalia, the difference between us," Nico began stiffly. "Is that Elsa was the only thing I had to lose. But now I've lost her. So I'm going to get her back, or die trying. She's the only thing I have left. All of you have something. I have nothing. Elsa was the one thing keeping me here." Nico stood abruptly and stormed out of there. He made his way to the Hades cabin. All the ice and snow was gone from Camp Half-Blood. Elsa's ice palace was gone. Just like Elsa. Everything she had put there, besides her memories, was gone.
Except her belongings inside of the Hades cabin. But Nico was going to put those in a safe place to make sure that nobody would find, take or steal them. He opened the door of the cabin, where the bag was right inside. He hid it under a bed in the corner, where it would be difficult to spot or find if you weren't close to the ground or looking for it.
Nico squeezed his eyes shut and braced himself against the wall of the cabin.
"I'm coming for you, Elsa." He whispered. "I'm going to find you."
Elsa screamed as she was transported from Camp Half-Blood to some foreign place. She was shoved to the ground by her mother. Elsa let out a cry as she hit the ice floor, catching herself using her palms. It hurt her hands, absorbing the shock of the impact.
"Guess what Elsa?" Khione purred condescendingly. "You're going to be my slave. I told you this would happen. And now it has."
Elsa winced, looking up at Khione with fear in her eyes.
"What do you want from me?" Elsa asked, tears sliding down her cheeks.
"Right now?" Khione smirked. "I want you to put on the uniform I have laid out for you in your room." Khione pointed to a door way. "Don't make me use force, Elsa." Elsa nodded, scurrying through the doorway. The walls were plain inside the tiny room. There was a bed, but it looked more like a cot than anything else. There was nothing else to the room. Just the bed. The walls were plain. The doorway was the only thing interesting of the four walls. On the bed was a white traditional Greek dress with a halter neck. Elsa removed her clothes and put the dress on. Underneath were accessories and jewelry along with a pair of shoes.
Elsa put on the tan leather colored traditional Greek sandals almost like she had done it a million times before, though she had never put them on before. The second she touched them, she knew what to do. The same went for the jewelry. There was a short choker. It was a white ribbon with a silver snowflake charm and two little chains on it. There was another necklace composed of several tiny chains. There was a silver belt with chains, and headband with multiple tiny chains. There were two chain bracelets, and two chain anklets. Everything but the larger necklace immediately fit perfectly upon putting them on. Elsa had re-braided her hair to a braid down the middle of her back. After Elsa put everything on, she noticed that she couldn't take the jewelry off. She began to tug at it, panicking. She rushed back out to Khione who was waiting for her.
"Oh, you can't take those off." Khione informed Elsa smugly. "Those are there to stay. They're magical. Because you are wearing them, I have complete control over you. Your powers will only work if I want them to, and only in ways that I want them to. You can't even speak if I don't allow you to." Elsa tried to speak, but she physically could not. "Do you want to speak?" Khione smirked at Elsa, who nodded furiously.
"What about Nico and the others?" Elsa got out. "They'll look for me! They'll try to find me!" Tears rolled down Elsa's cheeks. She was desperate.
"Oh, they won't remember you." Khione smirked, brushing it off. "Why don't we watch as Nico forgets who you are, and that he ever even knew you, the way everyone else you met at Camp Half-Blood will." Elsa made an inhuman noise of sadness.
Khione laughed, creating a screen of ice. A projection of Nico in the Hades cabin came from who-knew-where. He was crying, talking to Elsa, promising that he would find her, even though he had no knowledge that she was indeed able to hear. Elsa began crying harder, reaching out to Nico with a hand.
"Three… Two… One…" Khione snapped her fingers. The noise echoed more than it should have.
Nico looked up from the floor. Why was he crying? He didn't know why. He stood up straight, wiped away the tears, and stepped away from the wall. He felt… Nothing…
Why was he at Camp Half-Blood again? Nico didn't know why…
He frowned, confused.
"Oh, let's add some fake memories of ordinary life for Nico, too." Khione purred. Elsa cried harder, shaking her head. This was torture for her. But Nico would never know that his heart was frozen. Unless Nico managed to thaw his heart on accident… It would remain frozen his whole life.
Not only would Elsa lose her best friend and brother, but Nico would never be able to fall in love with anyone but one person. And he didn't even know the cause of this.
Nico then remembered. He was checking out the new Hades cabin and then he'd thought of Bianca, thinking of how she might react upon seeing how he had grown and everything had changed. He wiped away his tears, put on his jacket and sword, and left the cabin, hands in his pockets, wondering where he'd go next.
That night, as Elsa lay in her cot, her shoes, accessories, and jewelry still on, she remembered. Bianca and Anna still remembered her. They still cared.
She tried to hold onto that.
A/N: And that is how GK,SQ fits into both the PJO and HOO series.
