After the battle that had ended with the death of 3 of the 4 Gods of the Mechanic Empire in the Spiritual World, the forces of The Adamant Land had collected defeats in the world of Minos.
After Callie joined Aurae and began hunting down the last remaining God of the enemy forces on the planet, many alien outposts on that world were destroyed, marking the loss of territory for that force.
The Divine Continent and the Continent of Beasts had been thoroughly cleansed of alien forces until only in the Ancestral Sea were there still alien territories in this world.
With the decrease in the number of men in the invading forces and their loss of territories, the millions of inhabitants who had surrendered to them out of fear that the local forces would lose the War of the Worlds began to change their minds.
