Description: With the time-viewer they follow the events that got Kai's parents deported to a Jovian penal colony and then lost in space. They're archaeologists exploring what used to be Chicago, a Tabu Zone, now a plain of fused volcanic glass (Was Chicago nuked?). But an officer of the Air Patrol/Future cosmonaut finds them and deports them, ignoring the ancient safe they found. In trying to track down the safe, they end up with that Air Patrol officer in 1871 Chicago, and his fight with Dion starts the Great Chicago Fire, and he zooms off on anti-gravity belt, so they leave him behind with the Chicago fire raging. The evidence of the safe exonerates Kai's parents in absentia.
