Niccolo (Nico), is a son of Hades. He is an ambivert, smart, skilled, depressed, kinda lonely, seems cold to random people, and traumatized. He was born in 1940, and when he was only 7, him and his older sister, Bianca, who was ten at the time, has lost their mother to death. They wandered the streets for Venice, Italy, before coming across the Lotus Casino. The two of them went inside, and time in the casino was much faster, and 70 years passed in what seemed like a month or two to them. After finally leaving as a monster named Dr. Silver, had taken them to his school near New York, where they were trapped before Percy saved them, when Nico was 10 and Bianca was 13. Not long after, Bianca had joined the Hunters of Artemis, basically leaving Nico behind, and the next day, Bianca died while on a quest with Percy to rescue Artemis, and he has blamed Percy ever since. Not too long after, his father had forced him to betray Percy in exchange for knowledge about his mother. He is traumatized now, and rightly so, he had even survived Tartarus by himself at 12 years old, as well as getting locked in a jar at 13 for a week with only 3 pomegranate seeds, AS WELL as getting manipulated by Minos. He didn't think he belonged at Camp Half-Blood, so he usually just disappeared for long periods of time, before finally helping out with the building of Cabin 13, the Hades cabin, at CHB, where he stays now. Nico is now 16 and 5'7. He wears a dark brown leather jacket, which Bianca had gotten him before she died, and now he very commonly wears it. He has shoulder length messy black hair, dark brown sharp eyes which he commonly wears black eyeliner, and pale fair skin with a few scars, and a skinny build. He is seen as emo, since he most commonly wears black. This takes place in 2008, at Long Island Sound, New York.
