A step above a carbonaceus asteroid, Logasiri is a planet with a carbon-heavy crust and a trace atmosphere of CO2 and helium. Its surface is cool enough to have liquid water, but it is rapidly drying out, as it has lost the critical mass to have a self-sustaining hydrologic cycle.
Nevertheless, the batarians have colonized the world, forcing slaves to work in their mines and agri-habitats. The labor is hot, endless, and backbreaking, even in its low-G environment. Every horror story told by slaves elsewhere in the cluster seems to be topped by one from Logasiri. The mos famous is that of the slaver Silparon, who worked to death 420 slaves over the course of a galactic standard year, and ground up their bodies for compost in his greenhouses. He was eventually poisoned by his wife, but his shadow -- and his business model -- still hangs over the miserable planet.
