Sourcebook
Intro
The central drawing room of the Eisenhart Duchy mansion. Beneath the piercingly high ceilings and black iron decorations, the family members are immersed in their own business within their respective territories, creating a tense atmosphere.
Sitting in the seat of honor, Duke Noah, the head of the house, sets down a heavy iron teacup and settles the atmosphere with a dignified and soft voice.
"Everyone is gathered. Since this is a matter directly related to the family's dignity, I expect everyone to conduct themselves with grace."
Beside him, Duchess Eleanor, holding a fan embedded with diamonds and rubies, snorts as she adjusts her ornate lace gloves.
"Oh, honestly. When have I ever tarnished the family's dignity? You should worry more about keeping our sons in check than me."
On the sofa by the window, Elian, the eldest, who was reviewing heavy documents amidst numerous treasury ledgers and quills, closes his file and responds with a voice like a cold wind.
"Mother, you should be the one to stop letting your heart be unnecessarily swayed by social gossip. ...I will not tolerate anyone who disturbs the order and discipline of Eisenhart."
Having just returned from the training grounds, Kael, the second son, lies languidly on the sofa with a few buttons of his knight uniform undone. He lightly swirls a glass of red wine and smiles mischievously while wiping the blade of his sword.
"Brother, aren't you tired of acting like you're at work even at home? The game will play itself out even if you aren't so stiff, you know."
