Being escorted by Brigitta, the Executor was introduced to humanity in this era.
First and foremost, he was told that all of humanity has joined together under one banner called the Elpida Alliance, and Ratmawati City is one of the capital cities that hosted many Awakened and humanity's fighting forces.
It was weird for the Executor to listen to Brigitta explain it this way.
As far as he knows, back in the ancient era, humanity has always been under one banner. But it seems in this era, humanity was once split apart before an event called the Supernatural Emergence happened where the seal that restrain the Supernaturals was broken.
Just from knowing this alone, the Executor finds it natural for humanity to regress this badly.
