Prologue

My 7th birthday was the day my Uncle left. Ten years later, I've just come out of my second war. Then, out of nowhere, my uncle comes back with a bunch of Cosplayers and a pirate dude that's accusing me of being a terrorist. Fun, right?
(I'm sorry I'm terrible at descriptions. I hope this story is okay; it's one of the first I'm fairly proud of. And I don't own Percy Jackson, Magnus Chase, or Avengers. Rick Riordan and Marvel own everything except for the plot and Dakota)
