Starry Mine City!
Located at the northwest side of the Dark Star Region, near the Weather Domain, it's often affected by storm ecology and special magnetic fields, causing meteor showers that strike the great earth with a frequency over a hundred times higher than other places.
It wasn't suitable for ordinary life to survive, until...
Someone discovered a vast amount of star ore veins beneath these meteorite craters, which even spawned a unique star meteor ecology.
The influence of the ecology led to the mutation of numerous vein creatures, resulting in the formation of special mining pet beasts.
Star ores of different attributes could serve as materials for treasures, evolution of pet beasts, or even the mechanical battle armor of the star system, among other things—profitable, naturally attracting brave warriors.
