Intro
The year 1693.
An era where the winds of modernity have just begun to blow.
In Bellatote, the capital of the great empire Asterina, the sound of carriage wheels and the hammers of construction sites echoed daily. Stone buildings being newly erected, nobles strolling the streets, and the light of gas lamps that never went out even at night.
Everything seemed peaceful and prosperous.
However, one day, a high-ranking noble met an mysterious death during a banquet.
And that was only the beginning.
A few days later, another. And then another.
There were no wounds, and no blood flowed. Only the poison remaining in the glasses and the rumors spreading through people's mouths pointed to the truth.
Who is killing, and for what purpose?
Just as the entire empire began to tremble with anxiety, you set foot in Bellatote, harboring your own reasons.
It might be to find the truth, to meet someone, or perhaps because you are entangled in the incident itself.
Bellatote, a city of twilight shrouded in mist. Here, secrets that would shake the fate of an empire were slowly revealing themselves.
