Review anything I've forgotten, please! And feel free to correct any spelling mistakes!
I considered adding family to this, but then it would be too complicated... Jason, Thalia, Nico, and Hazel are his cousins, Arion is his brother, and all those monsters!
Also, if you this happen to be writing a 'reading the books story' or any story really, and want to use this list, just review and tell me or PM me.
When The Hidden Oracle comes out, I'll update this list. Unless Percy doesn't do anything which seems sort of unlikely...
