Sorry, I dozed off lol. So maybe a place that was settled thousands of years ago. Major hive cities grew from the industry driven by it's mineral wealth. However now that the planet and it's neighboring world's have been depleted, there's nothing backing it so it has started to fall into decay. Many of the noble houses have pulled out. Much of the population has stagnated into poverty, even by Imperial standards which is already very low. The only reason why it is even on a map is because of a large space station in orbit which is used as a refueling and resupply point for starships. But overall the station itself has more strategic value than the planet itself. 

I really do think that at its heart, 40k is a horror story on so many levels.
