Evolution

This planet was to be the new, better Earth. But it needed to be wrangled under control, made habitable for human beings... in one word: terraformed. The fauna and flora were much more aggressive than anything on the old Terra was. The humans and other big predatory mammals ruled over the Earth - but here, even after all the work put into Safehold by Pei Shan-wei and her crews, one thing was clear: On this world, the rulers of the Earth will always play second fiddle. On this world the pinnacle of evolution had six legs and was very distinctly reptilian.
