Time spheres are small, two-seated modules designed to withstand any reasonable amount of buffeting that might occur when the machine finally comes to rest in a different time period. At the very least, the self-contained atmosphere should give the occupants time to “reverse course” should they discover that conditions outside are too hostile to disembark. The time sphere carries sensors designed to test outside conditions immediately upon arrival.
The temporal displacement mechanism itself is arranged around the inside of the sphere, giving the occupants full access to the electronics in case of emergency. The main computer has all programs necessary to operate the machine and is crammed with historical and linguistic information, electronic encyclopedias, and any other information that might be necessary to survive in a different time. Operation of the time sphere is quite simple for characters familiar with computers. One simply sets the desired date and time and presses the “Go” button.
Time spheres are not sold commercially. In fact, doing so is illegal, but the plans to construct them are quite common. The components have a total purchase DC of 36. Building a time sphere chassis takes 12 hours and requires a successful Craft (mechanical) skill check (DC 25). Building and filling the time sphere’s computer (a much more daunting exercise) takes 120 hours and requires a successful Craft (electronic) check (DC 35).
Time spheres have the following statistics:
Crew 2; Passengers 0; Cargo 120 lb.; Defense 6; Hardness 5; Hit Points 24; Size Huge; Purchase DC: 65; Restriction: Illegal (+4).
