Note: This is only the first piece. I was worried about how it might turn out. A piece of the randomness I came up with yesterday is now open for your perusal.

Etheria stared at the girl across the room, unable (or perhaps just unwilling) to believe what her traitorous eyes were telling her. She herself stood about twelve feet away, blinking in surprise and occasionally glancing down at her left hand, which glowed eerily.
"Who in the name of Utopia are you?" Etheria noted that as she spoke, her voice sounded... off. It echoed too much. As if it were bouncing off of physical objects to be heard more than once. The girl felt a chill run razors through her stomach.
"I'm Sara." Etheria's doppelganger sounded uncertain, as though the answer to that question should have been obvious. If Etheria hadn't been so scared, she would have been offended. "Aren't you going to ask me what my wish is?" Sara seemed more curious than concerned, but even she should have been able to tell that something was wrong. Etheria swayed, feeling the force of gravity trying to drag her to the ground. This wasn't supposed to be happening! Stuff like this had stopped occurring almost five thousand years ago!

"Hello? Genie?" Sara took a faltering step forward. That brought Etheria out of her reverie. Straightening, she met Sara's gaze full-force. Ah, there was a difference. While Etheria's eyes were a pretty shade of maroon, this "Sara" had drab, brown eyes.
"My name is not 'Genie,'" she snapped, scowling. "And why in the name of Utopia should I care what your wishes are?" As Etheria finished, her counterpart looked stunned, perhaps even a little hurt. The girl took satisfaction in being able to effect others in such a way.
"Well, I thought... I thought all genies answered to that." Sara began to fiddle with something, and Etheria noticed the spellbook for the first time.
'Oh, no...' All those history lessons. And yet... she had never paid enough attention. She didn't know how to undo the spell. She was stuck.
