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.

You were so out of it that you didn't even notice the building alarms going on, the lights in the building turning red, you only snapped out of it when you felt someone grab you, the main doctor.

He unchained you rather quickly, and with shaky hands, he guided you out of the room and into chaos

Though, you were so hazy it didn't register in your mind.

You were being dragged somewhere until the doctor stopped and you could barely make out the four tall figures at the end of the hallway.

"The slender brother's" the doctor muttered with a mix of amazement and fear at the first time seeing them, but he had to get you out as they were here for you.

Their soulmate.
