Arrival of the Ghost King [PJO x HP]

Nico is fixing his relationship with his father, and building up a new one with a certain Apollo kid. And that was the plan, until his father told him to round up some ghosts for trial.

Alright, round up some ghosts from an abandoned castle, not too hard. And that was the plan, until he's flung back into 1977 because of Hecate (apparently, she was testing out time travel) into a castle full of wizards.

Okay, time for plan C: find two demigods, get back to the present, and then, finally, round up the ghosts and send them to Hades.

And that was the plan...
