Okay, so about this story, if the description couldn't be as long as it is on Wattpad, so I wrote most of what I have on Wattpad here.
Any demigod who has been into the Labyrinth before has this curse on them (created by Hera) so that if they go into Tartarus, they get sent to the Glade. Of course, Nico, Percy and Annabeth are the first and only demigods to fall into Tartarus, so the three of them are sent there. So, when Nico went into Tartarus, another copy of him was made and the real him fell into unconsciousness, waiting for Percy and Annabeth. Then when Percy and Annabeth fell, they split into real Percy and Annabeth and fake Percy and Annabeth. Real Percy, Nico and Annabeth disappeared into darkness, into the Glade (for Percy and Nico) and to the girls' version of the Glade (for Annabeth). Fake Nico had been captured by Gaea and the twin Giants and fake Percy and Annabeth went through Tartarus. Once the 'quest' is done, their memories of everything their copies went through will come back to them.
