Coins
As she stood there in the alley, her heart raced with a mixture of fear and anticipation. Turning her head towards the bum, she noticed that he had produced another coin in his palm, its silver surface seemingly imbued with secrets and possibilities. He nodded and tossed it towards her. She caught it this time, and with one swift motion, she hurled it towards the brick wall.
The air seemed to ripple as the coin connected with the wall, and the world around her wavered for a split second. But when her surroundings stabilized, she returned to her luxurious penthouse apartment. The scent of opulence filled the air, and the glittering cityscape lay before her.
