There was no such rule. As long as they were guests of the princes, they were not to be searched. This would only be possible if any of the guests were not an invitee of the royal highnesses.
"Je suis désolé, but this is an order from the king. The third prince is not allowed to have guests in the royal mansion if they are not thoroughly searched," the royal guard explained.
"What?" Santino was stunned. "Since when?"
The royal guard did not respond.
An annoyed breath fled Santino's nose, and he turned around. He pulled his phone out of his pocket and dialed Draven's number.
[Is there a problem, Santino?]
"Yes, young master. The guard at the door is not letting us in unless your guest is searched," Santino reported.
[Who said that?]
