I saw a lot of videos saying that Sally was 7 and was killed in a forest later found by Slenderman? Also heard she murdered his uncle with a kitchen knife (The rest as the video said) I guess there are diferent versions...
She was originally 6-9, but the creator changed her to be 12. He did that to her in a forest and found by Slenderman, and I'm not sure if Jonny was arrested or if she got revenge or what, but yeah.
she was originally 8 in the original story, but has now been revamped to be 12 (well, according to google she was originally 8, but it’s your au! She can be whatever age you want :D)
