Nico was born DIFFERENT, but he grew up broken. Yet a prophecy was set upon him when he was ten. He has to guard the Doors of Death with another boy his aged. One other Different person. Both of them grew up in different worlds, One in Dublin, Ireland (Artemis Fowl series) one in two different time eras and in a broken world.( Percy Jackson and the Olympians + Heroes of Olympus series) I hope you enjoy. PS there both going to get pure black wings like Thantos's and are both blessed with the powers of Eros.
