The divisions had already been moving out of the mothership before the two gem kings arrived and fought with Thunder Drake. This was why Arthur was able to witness the fight.
He was in his mobile fortress with the goal of moving to the border of the domain when the two gem kings arrived. Now that the fight had ended and his orders had been confirmed by headquarters, he continued his journey to the border.
He wasn't the only one who was asked to move out and get to the border of the domain as soon as possible. All ten divisions were asked to do this.
They were also scattered in every direction. They were ordered to form a circle around the border of the domain. When this is achieved, they will proceed to the next and main part of the campaign.
The goal of this campaign is to repel the gem people. This can only be achieved by taking complete control of the world.
