History
Not much is known about No Man's Land/Gunsmoke before the Project SEEDS ships crash landed on it's surface. What is known is that several species of animals including sandworms and a group of sentient hive-minded insects lived in it's desolate environments before "The Big Fall." 150 years prior to the series' beginning, Millions Knives caused a malfunction in the Project SEEDS fleet trajectory with the intent of crashing the fleet into the planet's surface. Thanks to the efforts of Rem Saverem, fragments of the fleet were able to make crash landings on the surface and survive impact, bringing humanity to the planet for the first time, quite by accident.

For the next 150 years humanity would struggle to survive in the planet's desolate environment, utilizing plants found in the remanents of the crashed ships for resources such as food and water while building cities and towns around them. Over time what would become known as the Seven Cities would be built, making them the cultural and political hubs of the planet.
