Description[]
As with Pania, Lemnia had mining facilities in orbit, remotely controlling machines on the planet's surface to recover Lemnia's highly valued transuranic elements. Unfortunately, the miners made no secret of their presence, and to find all traces of them and wipe them out, all the Reapers needed to do was access the extranet.
