The precursor base would be called Precursor Vehicle Facility, and the story would be that the precursors found out that caraar is less effective in the sky, so they moved there and built a base. They created the sky dragon so no one would dare to come up in the sky and no one would find the base. The reason it is called the vehicle facility is because you can find blueprints for flying vehicles such as the hovermoth and the fly clops.
