     Jason woke up rubbing his eyes. Percy was screaming into his eyes," Get up Sparkly! We got work to do." He punched him in the face.

     "You did not that was going to end well!" " Guys! Get your demigod butt here now!" Nico yelled from the door," Mcgonagall's telling us something."

     "I want you to go to the Room of Requirement, Harry has set up a Defence against the dark arts group. I want you to help them prepare for a upcoming- Ah there they are." All the demigods turned their head towards the three boys.

     "As I was saying, I want you to help them for a upcoming battle against Greek monsters. Train them to use weapons. Here are the details." With that, she left briskly.

      Everyone looked at the note Mcgonagall gave them. Room of Requirement, 7.30.

《Time skip brought to you by Clarisse and her sword》

     As Annabeth and Piper entered the room, they saw a magnificent hall with pillars and cushions." Hiya guys!" Percy said in his poatic fashion." We are here to help you battle with a oncoming battle." 

     "Harry is already teaching us. What is a dumb blonde and a bunch of teenagers gonna do?" A Hufflepuff student mockly asked. Immediatly, Annabeth's fist connected with his cheek than his eye. He fell on his back and rolled around, groaning." Dumb blonde? Im gonna end him!"

     Percy and Piper had to restrain her to actually kill the student." As you can see, we are stronger than you think. Harry can teach you your useless spells while we can teach you how to actually fight. Deal?"

      Everyone nodded.
