High in the clouds of Venus, there is a maximum security prison named Purgatory, there a bunch of political prisoners are kept, they are charged with various crimes, but the real reason they are there is because they have run afoul of the megacorporation Cybercom, the Purgatory Prison is a giant dirigible about a kilometer wide, it is filled with breathable gases that are lighter than the surrounding atmosphere, therefore it floats. Purgatory drifts with the Venusian Jetstream going around the planet every four days. The inmates of Purgatory are put to various tasks with the long term goal of terraforming the planet. This could be an introductory adventure for the PCs. A number of comets are heading toward impact with the planet, they carry a vital ingredient that the planet lacks, water.
Out at the Venus-Sun L1 point is a giant solar shade periodically blocking all sunlight from reaching the planet for 12 hours at a time, followed by only partially blocking sunlight for 12 hours allowing for Earth levels of Sunlight, although the Sun's disk still appears larger as seen from the cloud tops than from Earth, from Purgatory's perspective it experiences two 12-hour periods of daylight separated by two 12-hour periods of night, this means the total solar illumination Venus receives over a 4 day period is about the same Mars gets with the cloud tops reflecting most of that back into space. Venus holds a lot of hear however, it will take centuries to cool down.
Venus gets over a 4 day period a total of 24 hours of Earth level sunlight and 60 hours of darkness when you add in the part of the planet facing away from the Sun, which gets a full 48 hours of darkness during that time.
