@internutter Hey, I noticed this part ""Until they surveyed Rentin IV for potentially useful chemistry and resources. It scanned as non-hostile and **none of the extant life was non-toxic.** Safe for both the crew of the Seeker and their Ships' Human Gis. They camped in varying landing sites for weeks at a time, gathering samples and analysing the things they found there. The crew didn't notice for three such campsites that something was missing.""

I think you meant to have it read "None of the extant life was toxic".   Otherwise it actually reads as "All of the life was toxic".  Since you have the double-negative in there.  ;-)  Just a head's up.
