Before this, Beluti also mentioned that Night Spirit is an extremely rare type of magic creature that can only be born in filth.
It usually appears in places full of filth, such as ancient battlefields where massive bloodshed occurred, slaughterhouses, or towns where large-scale plague outbreaks happened. Only in such places where catastrophic events and mass casualties have occurred might a Night Spirit be nurtured.
In the Source World, such places do exist, and there are even quite a few.
However, the place that satisfies the conditions for the birth of a large number of Night Spirits is still only the former territory of "that empire," which is now isolated by the Nanierga Front outside the Source World in the Black Land.
It is the place where the largest and strongest empire in the Source once perished, a graveyard of countless lives.
The battles and casualties that occurred there are countless.
