Gehenna
There was a tale that even a peasant was privileged to hear.
It was told across all nations, clans, and classes of people.
It was a history that divided the world into the five distinct continents as we know them today.
It was a story of destruction and chaos—the story of the first major rift shattering.
Humans, at that point, were just getting used to the changes and anomalies brought by rifts. They were adjusting.
Then, a rift far stronger than any they had conquered so far appeared.
Historians claim it may have been a tier VI rift, while some ancient scribes insist it was a tier V or IV.
However, there was no way to truly know what tier of rift it was, as humans at that time had not yet discovered the trick to discerning the tiers of rifts.
The world was united back then and fought as one.
But the disaster was so great that it cut the world's population in half.
