Possible NonCon as well though we will see.
So for the last year or so, I've found myself highly interested in the Slenderman Mythos.
For those of you who don't know who Slenderman is, you can check him out here
This game would consist of two characters ( friends, rivals, whatever ) that are being stalked by Slenderman. While he normally goes after children, Slenderman is known to stalk young adults as well. ( I typically believe this is because these particular young adults escaped his clutches when they were children and he is coming back to finish the job. That is my own personal theory. ) Anyway, somewhere along this line, one of the young adults is taken by Slenderman and becomes his proxy. A proxy is a "slave" to Slenderman. The proxy does whatever he/she is told to do by Slendy. So the proxy is sent back into the city where he/she was captured from. His/Her job now is to bring the other character into the woods so Slendy can get that character. Of course, something goes wrong and something else happens.
Anyway, we can discuss more over PMs if anyone might be interested.
