The coin glows a deep yellow for an instant. A sudden dark swishing out of the corner of your eye draws your attention to the girl across the park.

She looks at herself in shock for a moment before, bizarrely, darkening in skin tone. After a moment, she continues on with her day as if nothing had happened, looking for all the world like a typical Muslim woman.
Well, that was certainly unexpected. You pick up the coin, watching the modestly-dressed woman walk away with the swirl of her dress. What to try next?
