During his stay, he learns a lot about their world, and the storm that's brewing within the Wizarding community. As Hecate watches, could this allude to a future role for Nico in the Wizarding world?

What happens when Nico Di Angelo accidentally texts Tony Stark? ~~~ Be prepared for hilarious drama, very weird author's notes, and lots of fanart and memes. There are also a few random chapters at the end of this that are basically one-shots related to the story. ~~~ DISCLAIMER: I am not Rick Riordan nor Stan Lee, which means (unfortunately) I do not own Heroes of Olympus or the Avengers. ~~~ Btw, this has Solangelo in it, so if you don't ship it, don't read this. ~~~ Why did it take me thirty minutes to come up with that? ^ ~~~ (Completed May 17, 2020)

[The amazing trope of the Son-Of-Hades, Nico Di Angelo going to Hogwarts! I've seemed to read almost every fanfic for this trope that's out there, so why not give it a try at it myself? wooh, this may suck? DISCLAIMER: I do not own the amazing Percy Jackson/Heroes Of Olympus/Trials of Apollo series, or the Harry Potter series. I also did not create the lovely fanart of Nico that is being used as a cover. I am unaware of who drew it, if you know, please tell me!! :) ] The war against Gaia has ended, but that doesn't mean Nico's heroic duties are over. His loving father, Hades, has had enough of the extra paperwork that a soul with the name of 'Tom Riddle' has caused, along with all the unregistered ghosts that seem to inhabit Hogwarts. And who's best to solve this problem? His son, Nico, of course. As Nico is ripped away from his normal way of life and sent to Scotland to help his father, he learns more about a forsaken woman betrayed by the gods and simultaneously helps the 15-year-old saviour of the Wizarding World, Harry Potter- No matter how annoying he is.

Percy had lost all his friends so he decided to leave. Thalia and Nico went with him, there was no way they would leave Percy alone, he would most likely get killed! So as the three children of the Big Three leave camp half-blood they return to Percy's apartment. When they arrive there they see something they wish they did not, Sally and Paul dead, brutally murdered. If Thalia and Nico weren't there to comfort Percy who knows what would happen? Over with the Avengers, Nick Fury was pacing back and forth looking at the three files on his desk. He called the Avengers in, they were the only ones capable of doing this. "I need you to detain and bring in Perseus Jackson, Thalia Grace and Nico Di Angelo." -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- I was just reading PJO/Avengers crossovers and I just noticed how cliche and over used my plotline is. Whoops no going back. Besides the fact that I have Thalia and Nico joining Percy but shut up Began: April 24, 2019 Completed: April 14, 2020
