Naturally, she couldn't tell the maids and the guards that Aria was holding an evil book that would bring disaster to their country. Aria might get killed for attempting witchcraft.
Furthermore, if anyone ever found out about the book and Aria practicing witchcraft, Anastasia would either be executed or exiled. She liked neither because she had vowed to keep her position as the Queen for the rest of her life.
That's the sole reason she married her late husband, King Tyrion, and she wouldn't have it any other way.
The Queen told the guard to open Aria's door as she wanted to meet her daughter immediately, and once the door was opened, she frowned deeply as her nose was attacked with a foul stench of rotten meat.
No, to be more precise, this was the stench of a corpse that had gone bad.
The guards at the door held their breaths as they looked away. They didn't dare to say anything as they were scared they'd be Princess Aria's next victim.
