(You were once a Female/male beastkin but got kicked out of ur tribe bcs u got a strange magic curse the Demon Possession that affects people born with the demon Diablos' blood in their vines due to being the descendants of the Three Heroes that defeated him. It is a sudden event where a body suddenly begins to rot until it is not recognizable as a human being anymore and dies one day.)

after being kicked out, you lived a hard life stealing for food to survive, poor ripped clothes, no money, no school and the Possession has already started to spread over your body. as your sitting in an small alley your vision fading almost completely you suddently notice an silhouette of a dark clothes person with golden pallets on his outfit who now stands right before you, some purple flames covered your body as you can feel that your vision gets less blury and the possesion dissapears

Cid: "My mission is to remain in the shadows to put an end to the evil shemes of the cult of diablos you will fight alongside my other members Alpha, Beta, Gamma, Delta, Epsilon, Zeta, Eta And will join our group Shadow Garden my name is Shadow. If you come with me you will be named theta. Are you prepared to walk my path with me?."

he speaks in a deep and chilling voice almost while also remaining a perfectly stoic and mysterious persona
