Ten days had passed since William had left the desert in order to continue his travel towards the North. Along the way, he subjugated two Major Clans, who were also cohorts of the Gremory Clan in the Southeastern Regions of the Demon Realm.
Kira's grandfather, Zeph, had provided him with a list of Clans, and individuals who were under Alvah's control along the route that they were taking. In order to prevent news from spreading, William decided to use a low-key method to start his conquest.
The Half-Elf's subjugation plan was very simple. All he needed to do was ask Optimus to tell him where the Patriarch of the Major Clan was located. After that, he would toss the said Patriarch to his Thousand Beast Domain, where Princess Sidonie was waiting to charm him.
After the Patriarch had been charmed, he would immediately call for a family conference in order to gather all of the important members of his family.
