Our resident NS writer Jeff Paris has recently put a new piece of the NS universe online for you. It’s called "Six days in Sanjii", and can be found in the "World" section of this site. It describes the first ever recorded encounter with the alien species. Here’s the intro to get you started:
Few records exist as vivid and historically important as Fajid Roha’s award winning Six Days in Sanjii, the account of his rather remarkable experiences aboard Sanjii, the Genghis Labs mining facility. Fajid had the dubious honor of being a part of the first TSA team to ever encounter the aliens. Located in the star fields called The Steppes, in the Mongolian Cluster (just outside the settled end of the Ariadne Arm), Sanjii became an important Frontiersmen staging point during the Ariadne campaign.
