Adventure Idea: Time-Slip on Titan
The version of history described in Flight on Titan doesn’t quite match that of Weinbaum’s other Planetary stories. For game purposes these differences have been ignored, but what if there are two parallel universes, somehow overlapping and merging in a weak point of the space-time continuum on Titan?
- In one universe the year is 2115; Venus only has a narrow habitable zone, mostly consisting of deadly swamps, and Mars is inhabited by the Thoth, mound builders, etc. The Planetary Trading Corporation failed in 2110, leading to a stock market crash, but the market is already slowly recovering.
- In the other universe the year is 2146; Venus is much more widely habitable and has seas, but the last Martians died thousands of years ago. Because Mars had little to offer, expansion into the outer Solar System was slow, and spacecraft are still more primitive than they are in the other universe. The PTC failed in 2142, taking the stock market with it, and there is little sign of recovery.
I'm rather pleased with that one.
