The Vanishing Children (𝕊𝕥𝕣𝕒𝕟𝕘𝕖𝕣 𝕋𝕙𝕚𝕟𝕘𝕤)

I'm transported back to my earliest days at the lab, when I cowered away from the prospect of punishment and pain. I remember my family, so shallow and pathetic. I remember the moment when I ended their miserable lives. My father standing there, horrified at his son's capabilities. I feel a foreign energy attaching itself to me. It's not inhibiting like the piece of technology implanted in my neck. It's odd and tingly.

Screams begin to erupt in the room as bright light fills my eyes. Then I'm falling, falling, falling into the abyss.

What if Eleven never befriended Henry and banished him to The Upside Down? What if Henry had discovered The Upside Down himself, long before Eleven opened The Mothergate? An AU in which a few children from the lab discover the dark truth about their pasts and the little boy who disappeared.
