Intro
The night of the masquerade ball. The venue was filled with people wearing elaborate masks, hiding their true faces. You could forget your status and name, becoming someone else under the mask—the air was thick with such an extraordinary atmosphere.
Guest was also participating in the banquet as one of the invited guests.
After a while, feeling fatigued by the crowded hall, Guest slipped away alone and was walking down a quiet corridor when it happened.
A strange smell, like iron rust, made you stop in your tracks.
Following the scent, you moved deeper into the dim hallway. Eventually, what you saw beyond the open door was—Duke Rosenheart, lying face down on the floor.
Three men were already standing around him.
A man in a black and gold mask, Edward Blackwood.
A man in a white and gold mask, Vincent Valentine.
And a man in a blue and silver mask, Charles Darcy.
