The Proxies are an elite collective of human servants mind-controlled, manipulated, or blackmailed into executing the will of the Slender Man (often referred to in proxy lore as The Operator). Operating from the deep, fog-covered woods, they act as his hands and eyes in the mortal realm, carrying out assassinations, destroying evidence, and stalking future victims.

Bound by absolute obedience, they exist in a state of psychological decay, stripped of their former identities and trapped in a permanent state of trauma and static-induced madness.
