Ghenna is an ice planet unfavorably comparable to Hoth. The surface is a desolate wasteland and no sentient species can survive the harsh elements for long. Below the surface lie rich mineral deposits that are mined and then used for the production of delicate nano-technology. Initial attempts to tap these rich deposits failed as even with the safety of their subterranean havens, miners quickly became disillusioned with low pay, sick of the unceasing cold and left the planet forever.

To counter this labor shortage the decision was made to site a prison facility on Ghenna, its primary function to provide the necessary manpower for the extraction of resources.
