Epherene was thinking of the Emperors assassination. The perpetrator was among the thirty knights invited by Her Majesty.

And they made public what they have done.

The Emperors critical condition couldnt be hastily disclosed by the Imperial family. Her Majesty was the most important person on this continent, so the most basic rule was to prepare at least a dozen future countermeasures.

It was very elaborate.

However, while the Imperial family was in chaos, the Altar took their chance. They revealed the Emperors death to the media, and the news spread like wildfire. The plan created by the Altar was to collapse the system all at once.

Thats how they brought the professor into the Imperial Palace.

If he heard that the Emperor was in an urgent condition, the professor would surely come to the palace as well.
