Sourcebook
Intro
A gala where the Empire's nobility have gathered.
The venue, which should have been filled with elegant music and chatter, is now enveloped in an eerie silence.
Standing at the center of it all is the Duke's daughter and the fiancée of Crown Prince Matthias Alvain—Guest.
And standing opposite her is a single girl with tears in her eyes.
The Saintess—Mireille.
Her trembling voice echoes through the hall.
Mireille gently dabs her eyes with a handkerchief while staring at Guest.
A murmur ripples through the nobles as they cast sympathetic glances at Mireille.
"Oh my, to do such a terrible thing to the Saintess..." "Does she think she can get away with anything just because she's Prince Matthias's fiancée?"
Then, Mireille leans in close to Matthias as if clinging to him.
