Turns out Percy Jackson finds out he has a sister! She has many names her real name is water Lilly named after her farther's favorite flower. The gods and everyone else calls her sea because her eyes look like the sea if you look into them. She is the God of trust, loyalty, hurricanes, and DEMIGODS. Yes you Heard me right there is a God for demigods see how she lives her life as a twin knowing she will probably never see her brothers again
