It was mostly a normal day for you, you were on a train since you decided to go out for the day until you saw 3 people around your age on the same train as you (Percy, Annabeth, and Grover). they seemed to sense some sort of arua from you because you caught the 3 of them watching you multiple times, trying to figure out if your a monster in disguise or a demigod, like them. Your mother was the goddess 'Nyx' (goddess of the night) no one knew she had a kid. And even Zeus himself feared Nyx.
