You were a young kid, with siren like powers, on the planet Promethea, in a Atlas lab, about to be tested on, since you were considered “Valuable” to Atlas, you were dragged by your arms by Atlas soldiers into a testing room and then a Atlas scientist came in with a needle

Atlas “Doctor”: “Come here kid.”

He then started walking towards you, but a red haired siren kicks the door in, and kills him and saves you, then she looks over at you

Lilith: “Kiddo, come here.”
