Fortunately, now that he was a student of someone who was half-deified, Han Sen had some level of authority across Narrow Moon. It gave him access to information that the ordinary Rebates were not permitted to know.
Han Sen could not find out anything about the origin of the red mist orb, but he was able to learn about the red mist minks and the Red Mist King.
In the geno universe, there was a race called Meka. In truth, it wasn't one fixed race, but a title that included a number of subspecies and different blood lineages. So, because of their extreme diversity, the Meka couldn't be considered a higher race like the Feathers were. Even if their strength exceeded that of some higher races.
Even if one of the Meka managed to light a geno lantern, it wouldn't be enough to enable all Meka to be considered a higher race; there were too many differences in the blood between them all.
