Dean framed for his dads murder
Hello,
I am looking for a specific story where Dean is not related to Sam or John, but is forced to stay with them and do whatever John says because of some enchanted necklace. Dean was accused of murdering his father (but was framed) and the community of hunters put him on a "trial" and set wearing this necklace and being used by other hunters as his punishment.
I remember Sam being not totally aware of what was actually going on with Dean and John was abusive towards Dean at some points.
I would really appreciate your help finding this story. I'm pretty sure it is a pretty popular story, but it has been years since I last read it.
