After bringing Henry to the Spatial Kingdom, Minos stayed permanently in that region of space to finally begin his experiments with Torne and develop methods compatible with what he had received from the ancient curse in Albano.
Before coming to his Spatial Kingdom, Minos took care of all his affairs in Dry City, even placing the idols that gathered the power of faith throughout the empire.
His wives stayed behind in Dry City to run the army and government, continuing their work to improve the empire's position in the face of the ice age and the alien invasion.
Gloria continued to deal with the Spiritual Church, increasing her importance not only through her level and position in the empire but also through her increasingly influential faction.
As for Minos' children and his wives, they were all in Dry City, living a little and enjoying the weeks they would have before returning to cultivation in seclusion.
