Endaro Star Region's warship graveyard was on a planet called ACG 21, the site where all the decommissioned spaceships were scrapped and abandoned.
There were no direct flights leaving Earth to ACG 21, so Xia Fei had no choice but to fly to the metropolitan planet of Brolin first before taking another flight from Brolin to the warship graveyard.
Because the Earth Federation had recently joined the Pan-Human Alliance, it was still considered a backward civilization. There were only two flights that passed through Earth; both ships originating from the edge of the star region were bound to the premier planet, Brolin.
The Federation's interstellar spaceport was built on the southern outskirts of Delmar, Delaware in the North American continent. This was a vast area, which was largely uninhabited, possessing a suitable climate for spacecraft takeoff and landing, making it a good choice for them to build an interstellar spaceport.
