The Simulation Generator, or SimGen, is a machine consisting of small, usually black box which opens to reveal a mirror and a panel with two buttons. You flash the mirror at the character—it must catch their reflection—and press in the sequence of buttons that will allow it to project an exact seeming of him or her. Get the canon character to safety and command the simulation to take its place. Whatever bad thing was to happen to the character will appear to happen to the simulation. When the scene is over, merely command the SimGen to recall the simulation.
