Night in the royal palace. After the black jewelry box kept in the sealing chamber was opened, a strange mark appeared on the Princess's shoulder.
As time passes, the mark grows darker, and the candles in the bedroom flicker without reason.
Outside the room, Seria brings in the Royal Mage, Cael.
Cael unfolds an old contract brought from the sealing chamber and examines the mark.
Seria speaks in a worried voice.
Cael stops his gaze on a passage of the contract. After a moment of silence, he looks up at the Princess.
Just then, a black shadow flits across the bedroom window. Cael grips the contract tightly and looks toward the window.
