Caleston is a Location in Mass Effect 3. Caleston is located in the Balor system within the Caleston Rift cluster. Locations can be explored while you traverse the galaxy. Locations may vary in size or scope, and may or may not have Missions associated to them. Some of them can only be scanned from atop the Normandy, while others can be landed on.
Caleston is the largest satellite of the gas giant Cernunnos. Ancient asteroid strikes deposited major lodes of element zero within the molten sulfur mantle. Eldfell-Ashland Energy's mining operations made it the largest source of starship drive core material in the Attican Traverse, which threatened Caleston's native biodiversity with industrial waste.
Caleston is wracked with volcanism due to tidal stresses from Cernunnos. Because of weak solar output, plant-like life on Caleston is not carbon-based and photosynthetic, but silicon-based and thermosynthetic, requiring heat rather than sunlight to power chemical reactions. These organisms flourish in volcanic vents and during solar flares, when Balor, Caleson's [sic] sun, can double or triple in luminosity. Oxygen-breathing habitation is not possible outside its many domed cities. Those cities are now feasts for the Reapers, who drove off Caleston's protective fleet and now threaten to puncture domes to force the population into submission.
