The forbidden zone Klaus's team had just cleared wasn't always known as the Ant Kingdom. It was a different zone many years ago.
About 30 years ago, it was known by a different name, for it contained different breeds of monsters.
However, one day, out of nowhere, an Ant Queen who had just entered the Sovereign stage appeared with her and soldiers. For two days, they hunted down and killed every last resident there, claiming the entire zone for themselves.
This Ant Queen then went ahead and, for years, continued to fortify her zone against unwanted guests.
Dozens of humans fell trying to hunt there.
However, everything changed when Klaus and his team appeared.
It was as if, the moment Klaus and his team arrived, the Queen knew it was over for her and her soldiers.
However, strangely, Klaus didn't attack her personally. Instead, he came to see her and even went out of his way to offer her an alliance.
This, of course, was an unexpected offer.
