As she spoke, you notice some odd things. Ms. Yannatou's ears were already quite small, but are they...pointed? And her eyes are different. You can't quite put your finger on it, but it's almost like the pupils and the corneas are merging into two tiny pools of pure blue.
Then you start to notice other things. The other students are starting to disappear, as though they were never there to begin with. The room is changing, looking less like a school and more like a rocky grotto with a--is that a waterfall?
Suddenly, you realize your desk is gone. Then your chair vanishes. Then Ms. Yannatou walks up to you. And she is very, very different. Her auburn hair is no longer tied up in a bun, but long and flowing along her shoulders. Her skin looks as pale and light as cold milk. And her clothes are different, because she's now wearing one of those weird toga-like dresses that you remember from the pictures in your textbook. Her feet are bare, but she moves like she's floating.
As she approaches, one of her hands grabs you under your chin and lifts your eyes up to her face. Her ears are pointed and every inch of her eyeballs is as blue as a bucket of paint. You try to say something, but it feels like you're being hypnotized, as though you feel nothing now but pure, unadulterated desire for this goddess.
"You must be wondering where you are and why I've brought you here. The answer is simple. I am a nymph, a spirit of nature, and I traveled to your world seeking a companion, for I am lonely here in my realm. And of all who I could I chosen, I choose you, my dear child."
Finally, you work up the nerve to speak. "But why would you want me? I'm no one. And I even if I was, I don't want to live here. I have a family, a life back in my world."
She puts a finger on your lips and you suddenly become silent. "I will not stand to hear your words of protest. If I wanted to, I could make your tongue shrivel up like a leaf, and you would be a mute for the remainder of your days. Now listen to what I have to say. I could give you a life beyond imagination. With my magic, I could make you anything you wanted to be."
She removes her finger, and your curiosity takes hold. "Wait. You could...change me?"
"Yes. Here, my power is limitless. I can make you into any form you desire. Personally, I would prefer to make you a satyr, for they are very much prized among my kind. But if you wish to become more handsome, or taller, or stronger, I would also do that. Maybe you'd like to trade your humanity for the simple life of a sacred animal, to be cared for and loved by me alone. I could even change your sex. You would be like a daughter to me, and I would teach you all I know of my magic."
"So what's the catch?"
"Very clever, child. You speak a certain truth, and so if you wish to return to your world and forget any of what you have seen, I will honor your request. But if you agree to live with me here forever, then I can make you mine. I promise, you will learn to love your new life."
