Riot Alenius was born to Naima Alenius along with her "Other Part", Salem. Really, Salem was planned to be Riot's brother, and he is related to her. But Dionysus was told something by the oracle which made Dionysus make Salem a "Guardian" or her "Other half". So a basic run down is, in the beginning, Naima was pregnant with one child, Riot. But Dionysus asked Eileithyia to make Naima pregnant with Salem, thought to make him just immortal, to protect her from dangers. And Eileithyia agreed. So one day, a second child appeared in Naima.
Things started horrible from the beginning. Right after Salem and Riot's birth, their house was stalked by something that looked like a disfigured human. Scared, Naima moved from Sweden to a small town in Alaska, USA. There, a slightly different monster stalked them. This one looked like a burnt alive human. Naima just let it go, never letting the children outside, nor letting them out of her sight. Until Salem was five and he went and killed it. Naima didn't know of this, until Salem became very violent when any sort of threat was posed to Riot. Dionysus appeared to Naima to tell her what Riot and Salem really are. Naima left them, though came back. She enrolled both Riot and Salem in fight classes. Then one day she took them to Camp.
