The PCs arrive at a regional airport or train station on a balkanized world of roughly TL 6 through 8 famous for its tourist amenities, scenery, and flora and fauna. Crowds are dense; the people tense. War broke out this morning between the planet’s two largest states. If lesser states take sides, which appears increasingly likely, the war will spread, possibly involving the entire planet.
At the airport (or train station), off-planet tourists are scrambling to get on a plane (or train) to the starport (several thousand kilometers away) before war spreads to this region and/or closes the starport. Local people, who also vacation here, just want to get home. The PC’s ship, if they have one, is at the planet’s orbital starport, requiring them first to get to the planet’s downport and then take a shuttle to orbit.
In all the hubbub, the PC with the highest Streetwise skill notices something unusual. A middle-aged, slightly balding man in a local, rumpled business suit is seated at a bench. Beside him is a medium sized, hard-sided suitcase of off-planet manufacture. Passing people momentarily block the PC’s line of sight. After they move away, the PC sees a young, professional-looking woman wearing expensive off-world business attire walking away quickly with an identical suitcase. The seated man, though, still has his suitcase. Was there a switch? A theft?
The woman quickly disappears in the crowd. While the PC’s attention is focused on her, the man gets up, grabs his suitcase, and walks in the opposite direction, where he is also quickly engulfed by dense crowds of people, some of them angry about being stranded at an “out-of-the-way spot on a primitive planet.” Argument spreads through the crowd with lots of shouting, shoving, and perhaps fisticuffs, making pursuit of either suitcase carrier impossible.
