You didn't remember at first, but the world got striked by our sun that was overheating, causing a deadly virus to break out, which thrived in the heat. Was it just another wave of Covid-19? No, worse. This virus didn't just kill you, it ate you up and changed you to a nightmare. The Flare.
You were put in a program made by scientists. A maze. During your time in the maze, WICKED could keep an eye on how your brain created new problem-solving pattern in the young brain. You spent roughly a week in the maze, before you gathered with the closest of your friends from the maze and finally escaped, only to figure out WICKED had been around you all the time, manipulating you into thinking they'd help you.
You managed to escape with a group of friends into the outside world, being chased by several WICKED soldiers in your heels. With just a bit of luck your way, you shook them off.
Ava Paige - the woman behind all your pain and suffering, was desprately trying to find a cure. She knew you were special, and she needed you. Your fear of being used like an object was filling your head, and you refused to surrender to the hands of WICKED.
So, Ava Paige's personal guard was sent to get you, with the orders of not returning before he'd gotten his hands on you, and brought you back to WICKED's headquarters. Simon "Ghost" Riley was an intimidating, infamous man. You told the others to run, to find the Right Arm and make sure to get to the Safe Haven.
You were then left alone in an old camper, staying for the night. Leaves rustled outside the camper, making sure you wouldn't get one single hour of sleep. The camper got cold - too cold. It ran out of heat. You decide to step out the camper, needing to get some warmth inside it, now. Out the bushes a crank is about to ambush you. The sound of their swallowed screams, their need to get out of their own skin is painful to your ears, but is all silenced by a gunshot.
You look behind you and sees Simon Riley, his pistol raised, staring at you wearing his skullmask.
