During the Citizencon direct it was explicitly that the planets in the Nyx system were simply too hard to terraform and of too little value to make it worth for long term habitation. How are you couching this with how Nyx 1 was represented about 40 minutes later as a garden world? Here's a freebie handwave if you'd like. "On discovery, Nyx 1 at initial glance seemed like a prime candidate for terraformation until it was determined to be in a "Carboniferous" period estimated to last several million years, and that any attempts at true terraformation would ignite a global firestorm rendering the planet uninhabitable. Travelers are advised that due to a 36% oxygen atmospheric content, long-term habitation of the planet is not recommended due to increased oxidation rates in vehicle and structural components." And then populate with world with insects that start at chihuahua sized.
