Meeting at Infinity

In an infinity of parallel worlds, many are the inventions which would paralyze less advanced worlds. One such invention was the one the noted physician Jome Kenard used to restore life & senses to the injured beauty Allyn Vage.
His strange machine had been imported from a seemingly primitive people on the world of Akkilmar. It worked, but its workings were incomprehensible even to Earth's best scientists. Nevertheless, once used, the doctor & his patient had been transformed into the lever that could topple a world!
