June described to Noah what had happened in the other world after their separation. Of course, she had brought up those topics only after the two of them had taken their time to catch up.
The Hive, the Council, and the Shandal Empire had lived in peace for many centuries after the migration. They all had to divide the world and create sources of materials, so they didn't have the time to fight each other.
However, small fights eventually happened. The other world had fewer resources due to the absence of the piece of Immortal Lands. Battles were inevitable, and they soon escalated into wars.
The Hive became the target of both Council and Empire. Noah's absence had made the two organizations believe that they could topple that force.
The situation didn't go as planned. June, the Demons, and Daniel revealed their immense potential after a few setbacks. Faith also betrayed the Council and brought a new wave of experts to the Hive, eventually ending those wars.
