^ son of hades in a book call the house of hades, he is the most mysterious of then all, we really don't get much from we knew a lot of anabeth from the PJ&O series but nico's has always been a question mark, we know morea about piper, hazel, leo etc. than we know from nico, does he still resent zeus for killing his mother? is he a kid who is just looking to please his father(the ending of the last olympian), or does he only follow his fathers rule went it suits his whims (bringing and attempting to bring people back from the death)?

we need it because it would allow us to better understand an established character that is mistery itself on this series, plus he is leading them there. which means he is the leader which puts him in an interesting situation since he normally tends to deal from the shadows (no pun inteded)
