After the battle, or rather massacre, of Monastery Of Chaos, Minos and his group stayed at this enemy base to wait for their troops to arrive, but also to conduct experiments with his ability.
With several enemies to serve as guinea pigs and also allies to receive powers from, Minos had several options besides his two wives and the General who had come with him to this place.
His ability was no secret to anyone, so as soon as his allies and Maximilian's party arrived at the Monastery of Chaos, victors in the battles with nearby enemies, he began his experiments.
As he had promised his two wives and the General, he continued with them two days after their arrival in the area, even before the people from Maximilian's group arrived.
