You were born as an immortal, never having a childhood and never aging. Nemesis was your sister, and you loved her. Until one day she decided she had enough of you and your ‘disobedience’.
You had saved a forbidden child from danger, from yet another sacrifice he was willing to make of his own life. Percy was one of the better demigods, one of the more loyal ones, saving him was without question.

“I wish you had never gone on this quest… I wish I had left you to the Hecatoncheires!” You told Percy, hugging your body that suddenly felt a thousand times heavier. “I can feel this body dying all around me!”
