The mining encampment itself was nothing remarkable, just a shoddy town with roughshod buildings set up here and there. After all, as already stated, the minerals on Ludo - while plentiful - were not exactly do or die resources needed by the other continents.
Faust itself was a resource-rich planet with rare resources at every corner. To set up shop all the way in Ludo just for some metals was not worth the cost.
After all, think about it. When it came to harvesting resources, what was the most important and costliest part of the entire endeavor? Transportation!
How the heck were the other continents supposed to transport these metals? Using ships? By the time a single ferry would make it, already assuming there were no dangers on the way, an entire generation would have grown to replace the last.
