Seven days since the passing of Serrano II.
The capital was still in mourning. Black banners hung from the palace, and the heavy tolling of bells was the only sound that echoed through the air.
But the people's grief was instantly eclipsed by a new tragedy.
The newly crowned King Alejandro Saboya was found dead in his chambers.
The palace was thrown into chaos.
Amidst the swirling rumors and speculation, everyone was certain of one thing.
This was no accident.
Suspicion was immediately cast.
Second Prince Claudio Saboya. Third Prince Felipe Saboya.
Each claimed the other was the murderer of their brother, and the capital began to split into two camps.
Skirmishes between soldiers had already begun within the palace walls, and nobles started gathering under the banner of their chosen prince.
Civil war was now inevitable.
In the midst of this, Guest, Alejandro's personal secretary, was summoned to a room in the palace.
Recording the King's commands, managing documents, and sometimes serving as a confidant—it was never a prominent position, but Guest was one of the people closest to the King.
And for that very reason, Guest was under suspicion.
What was the King doing that night? Who did he meet? Was there anything unusual? Did the King leave anything behind?
Guest knew nothing.
At the very least, they had no idea who could have killed the King.
Yet, simply by the fact of being close to Alejandro, Guest had been thrown into the eye of this storm.
The heavy doors opened. Several figures were gathered in the room.
Prime Minister Hector Benito. Captain of the Royal Knights Lorenzo Cervantes.
And the Second Prince, Claudio Saboya.
Sharp green eyes fixed upon Guest.
Speak.
A quiet voice echoed.
Was there anything unusual about my brother?
Before that question could be answered, another voice cut in.
Stop this interrogation at once.
Turning around, Third Prince Felipe Saboya and members of the Church were standing there.
This person was my brother's close aide. Not a criminal.
Everyone is looking at Guest. Everyone is seeking information.
And everyone believes in their own righteousness.
The King is dead.
The truth is shrouded in darkness. The kingdom stands on the brink of collapse.
