He reveals the amulet, and its secret

Mellannon rises between your legs, running his withered hands up your flat stomach and to your breasts. He looks down at you and smiles, a trace of your juices wetting his lips. He plucks at your straining nipples and you moan involuntarily. After a moment he gives you a pinch, just hard enough to make you cry out, and then releases both nipples. His hands move to his robe and he unties the neck, exposing his withered chest and a heavy amulet hanging around his neck. It seems little more than an iron plug on a leather cord. Could this be the amulet Tybard was speaking of?

"Yes," says. "It is the amulet he seeks. He thinks it is wasted by me, but he is too much the fool to even know that it has worked its magic on him each time we have met. After all, my dear, what could be more forgettable than a tired old elf like me?"

Mellannon reaches around his neck and slowly lifts the amulet away. You are beyond screaming in horror at what you see.

The kind, gentle old elf melts away by magic and in his place stands the bloodless remains of an emaciated corpse, held together by dried patches of flesh tufts of ancient hair. Mellannon's kindly old face is now a grotesque skull with parchment brown flesh tight over his bones and a lipless mouth smiling at you with brown teeth. His eyes glow red and within his mouth a tongue of purple flesh moves almost like a snake confronted by a predator. You realize in places where his flesh has rotten away you see more of this purple tissue, unwholesome and flexing, and between his legs dangles a cock made from the same.

"I have been and will be long after the worms have eaten the likes of Tybard," says the monster, the old man's voice coming from the lipless mouth. He returns the amulet to his neck and immediately the illusion is restored.

"Do not be afraid, child. If I had wanted you dead you would be dead. I appreciate your predicament. **** to a lowly beast like Tybard, **** to steal my amulet, only to discover..."

He quirks his head as if to suggest he does not need to explain what you just discovered.

"In all my years I have learned to enjoy the moment. So let us share one now, my lovely little cream cake. Then we can discuss what happens next."

You tremble as he reaches out to your breast once more and runs his fingers over your nipples. Despite what you know lurks beneath the illusion, his fingers are warm, his touch soft. It must fool every sense. Mellannon steps between your legs and slowly unties his robe, revealing a slender body, pale skinned and with a tuft of white hair between his legs. A fat cock dangles between his withered old thighs.

"Come, my dear," he says, and caresses your face. "Touch my root and understand that reality is only what you choose to accept."

You look at Mellannon's sweet, old man's face and his completely real cock dangling between his legs. There is no trace of the evil you just saw, but you know it is lurking beneath the surface. Fear and lust war within you, joined by the knowledge that your very life may depend upon how you react to Mellannon's revelation.
