The story at the moment is meant to take place after the Slenderman craze of the early 2010s died out. The reality it takes place in uses a system similar to the Tulpa Effect Theory, where belief=power, and after the craze died, Slenderman presumably vanished. In his place, a boy by the name of Erwin Bravo claims to be harboring the dormant form of Slenderman, now using a human vessel to conserve his power instead of maintaining a fully-fleged physical appearance.
I mainly want the story to focus on the proxies now serving Erwin Bravo, as now that the Slenderman's powers are significantly limited, he needs more lackeys to get work done. This need for a larger team of minions results in an organization operating out of a cluster of forests in Nebraska called the Children's Covert, who are slowly growing their numbers and building local belief in the Slenderman.
Any ways that I can expand upon this idea, or fine-tune it to work out any flaws? Feedback of any kind would be appreciated. Thanks in advance.
