Nico di Angelo has never really been welcomed or appreciated, but just one short year after the Second Giant War, things reached an all-time low for him. Gods and demigods alike seemed to forget his voyage through Tartarus and his quest to return the Athena Parthenos. Everyone just saw him as the creepy gay son of Hades. Well, everyone except the other Ten (the Seven plus Reyna, Thalia, and Will), a few scattered demigods, his father, and Persephone.
So he left.
Accompanied by his boyfriend, Will, Nico ran away from both camps and traveled the world, freelancing for the Gods in exchange for small blessings and supplies.
After six months of that, Hades called the Olympians and demanded that the couple was made gods when they died as a way to thank them for everything they did. They complied, only somewhat begrudgingly, and promised Nico the position of King of ghosts and god of shadows and PTSD. Will was promised the position of god of light, acceptance, and healing- specifically, healing of the mind, though he would have physical healing powers as well.
Now, Hades and Hecate are setting the young demigods up with a new task: to protect Harry Potter during the Triwizard Tournament that is to occur later this year.
Oh, what a joy.
