He's not a physical monster, oh no, that's too simple. He's much more subtle.
LADIES AND GENTLEMEN! COME ONE, COME ALL AND SEE THE AMAZING SLENDER MAN PERFORM HIS MOST AMAZING TRICK, "THE DISILLUSIONED MAN"!
Like all great tricks, it is composed of three parts; the pledge, the turn and the prestige!
The Pledge; the Slender Man presents, for your consideration, a perfectly ordinary human being! Feel free to inspect our lovely volunteer, ladies and gentlemen, I can assure you, he is quite human!
The Turn; the Slender Man, will perform an amazing transformative trick, using techniques familiar to certain citizens of the Orient and various holy men of the Himalayas. Indeed, many of you may be familiar with this technique, but for those of you who are not, do not be alarmed. What you're about to see is considered safe.
FREAKY MUMBO JUMBO
Ladies and gentlemen, the Slender Man has transformed this ordinary human into a Revenant! *pause for applause*
But it's not over yet, ladies and gentlemen!
The Prestige; the Slender Man turns his erstwhile servant back into a human! Oh yes, ladies and gentlemen, oh yes, he is that good! Take a bow, Slender Man, take a bow!
(Meanwhile, backstage, the true secret is revealed. There are no Revenants and there never were. Slender Man is a monster of the mind, not of the flesh. We were never transformed. He just made everyone think we were. I can see the scars now. I can see them all over. There was no superhumanity, no transformation. Another day, another lie, another day, another lie, another day, another goddamn motherfucking lielielielielielielielielielielielielielielielielielielelielielielielie
He got inside our heads he got inside all our heads and he told our heads to tell each other's heads that we were magic and powerful and gods and heroes and fuck fuck fuck there are no Revenants there are no Conduits it was all a lielielielielielielielielielielielielielielielielielielelielielielielie just another way to distract us to keep us in line we spend so much time fighting shadows we don't spend any time fighting the shadow of our entire reality that lies in our own hearts and the heart of every man and woman and child.
Pawns, pawns, we are all pawns, pawns, we are all pawns, pawns, we are all pawns, pawns, we are all pawns, pawns, we are all pawns, pawns, we are all pawns.)
