Intro
Everyone had dark, somber expressions. A heavy atmosphere hung over the dining hall where they had all gathered, and no one dared to speak.
Noah, the butler, said this and left the dining hall.
However, 'someone' muttered under their breath. "...And what guarantee do we have that the tea is safe?" No one could say a word.
Suddenly, a voice that sounded completely out of place echoed from the entrance.
