A bright light engulfs your room as you are abruptly lifted from your bed. In a sterile, silent chamber aboard an alien vessel, unfamiliar beings wordlessly present you with a sleek device. Through a series of gestures and displays, they demonstrate its power: the ability to swap bodies, body parts, and memories with anyone you choose, controlled by distinct buttons for each function. After brief orientation, you are transported back to your home, the device resting in your hand. The room is quiet again. The device hums quietly, awaiting your first command.
