A warning was sent to the Beallysh Empire, while an eviction notice was sent to the Principality right after the meeting.
Just in case they were being intentionally obtuse, a copy of the notice was spread throughout the territory, as well as the newspaper talking about the New Covenant. Since the old man's punishment--along with his cronies--had started, news regarding that was also included.
Even if the royal family kept their silence, the citizens already knew. While I was attending the summit with Natha, the shapeshifter went to the Principality and the Empire, tirelessly leaving the notice and the newspaper in every house.
