The Bronze-Carapace Insect Tribe is the tribe of the Ghost Immortal Race and one of the most ancient lineage in the Sacred Nether World. The Tribe has existed since the Desolate Era or even earlier.
Prime Ominous Grave's Opening
When the news that the Prime Ominous Grave would be soon opened spread throughout the Sacred Nether World, the Bronze-Carapace Insect Tribe was among many groups that went and camped right outside of the Prime Ominous Grave to wait until it would be opened.
This tribe are seems to be a gregarious species, fond of aggregating all its members into a giant swarm. They also seems to possess a hive-mind of sorts with one member acting as their leader and controlling all the others.
The Bronze-Carapace Insect Tribe can be compared to locusts; members of this tribe can eat almost anything, even the dirt on the ground. Living being eaten by the Bronze-Carapace Insects wouldn't leave behind even bones; everything would be eaten.
Their most dreadful aspect is their ability to reproduce. As long as the conditions are right, Bronze-Carapace Insects will immediately reproduce; the tribe can produce millions of offspring within a very short amount of time.
