I know this is different from my usual fics, but I just really love the Percy Jackson series of books, and I haven't found any ideas for fics until recently, so here you go.
Annabeth found herself holding up the sky, her vision blurring more and more by the second, but she could make a boy, about her age in shackles with a metal gag around his face, no. It wasn't some random half blood, it was Percy. She screamed for him, he tried to respond, but could only make muffled screams with the gag on, then she saw Luke approach Percy with his sword, and said,
"I'm sorry you had to see this Annabeth." before swinging his cutting open Percy's chest.
Annabeth woke up in a cold sweat, shook as fuck.
Percy woke up to someone tugging at his shirt sleeve, he looked up and saw Annabeth, her eyes filled with tears.
A: "Nightmare, could I-" she said while gesturing toward the blanket. Percy nodded while flipping up the covers, and Annabeth climbed in. After a couple of minutes, Percy thought,
"Ah fuck, Chirons gonna kill us in the morning." but that wasn't his priority right now, that was making sure Annabeth slept peacefully, and when he looked back down, she was already fast asleep, so he decided to get some sleep himself, feeling content that Annabeth was safe.
