Luna is a normal girl who is taken one day and told that she is too powerful to be allowed to live. She does not understand this because to her, the only thing she is good at is bartending. However, she also knows that in times of stress, she grows vines from her skin. When she begins to ask questions, twin brothers arrive to save her, killing the majority of people in their path. They tell her that she can trust them and ask that she come with them to a safer location. They take her home to their triplet brother. They choose to reveal that they are the sons of Aphrodite and Apollo, each with their own set of powers.

He is the first to advocate for Luna. The fates give a prophecy that she is meant to be the one to take down Zeus once and for all.
