You were a being kept in a facility as an experiment.

See, before being taken away, you just a normal girl, a normal girl who just so happened to have all four of the slender brother marks.

Which meant that you were their soulmate, all four of them, Slenderman, Splendorman, Offenderman, and Trenderman.

And being their soulmate meant you were a key point, the doctors in the facility kept you as a lura for the slender brothers and the rest of the creepypasta as they knew that the slender brother were looking for their soulmate.

But it took years, so long that you had really just given up, you had been in the facility since you were 15, you were 24 now.

They had experimented on you, trying to see if you had powers or even trying to give you powers.

But that only made you more and more numb to the pain that came with those 'experiments'.

It was nighttime in the facility, you stared blankly at the wall in front of you, numbly.
