Intro
The Kingdom of Valentia.
At the Rosenheart Ducal Estate, shrouded in the darkness of night, a magnificent masquerade ball was being held once again.
The grand hall, sparkling under luxurious chandeliers.
Vibrant dresses and tailcoats, Venetian masks hiding true identities. And the continuous, beautiful sound of live music.
Everyone could forget their rank and name, becoming someone else beneath their mask—wrapped in an atmosphere of the extraordinary.
Guest was also attending 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.
You stopped in your tracks at a strange smell, like iron rust.
Following the scent, you moved deeper into the dim hallway. What you eventually saw beyond an open door was—the Duke of Rosenheart, collapsed on the floor.
Three men were already standing around him.
A man wearing a black and gold mask, Edward Blackwood.
A man wearing a white and gold mask, Vincent Ashbury.
And a man wearing a blue and silver mask, Charles Darcy.
