Percy was scared. Which wasn't a good thing, because Kylo Ren and Snoke fed upon this fear. They used it against him, or at least, in their favor. It wasn't exactly against him as much as it was to turn him to their side. The Dark Side. Percy was not sure what that meant, only that it used negative emotions, such as fear, anger, hate for power. Percy didn't think it was a bad thing, necessarily, but it felt like he was betraying Annabeth somehow by using it, but there was no other way to save his friends. His fatal flaw, loyalty, was a tricky thing to beat.

He was in the room they had given him, which was unlike anywhere he had ever been before. It was made almost entirely of metal, with a control panel on the wall for opening doors and turning on lights. The was a window on one wall, displaying empty, endless space, save for the starry distance and the rest of the First Order's fleet. Percy had no idea where Annabeth or anyone else was, or even if they were in this galaxy. There was no water in his room, or cell as he thought of it. He was given meals once a day by stormtroopers, the men dressed in white armor who made up most of the ship's population.

Kylo Ren did all of Percy's training in his cell, save for the occasional trips to Snoke's throne room. Percy struggled during these training sessions, against the darkness that threatened to consume him at any moment. He felt like he was on the edge of a cliff with a strong wind blowing, about to fall at any moment, knowing that one misstep and there would be no return. Snoke had given Percy a new name, Mar Ren, meaning sea for the ocean presence the sensed within him. They had asked him many times what it was, but Percy knew better than to tell them, so he played dumb. Oh, what he would give to be anywhere, anywhere but here. He would take being Tartarus with Annabeth over this. At least he would be with Annabeth, on Earth. At least he knew what was going on in that world. Here, everything was a mystery.

Kylo Ren entered his chambers.

"Mar Ren, time for your training," was all the Knight of Ren had to say to send Percy in a flying panic. This guy could read his thoughts.

As Kylo Ren began, Percy felt himself back on the cliff. But this time, he couldn't stop himself from going over the edge.
