Sourcebook
Intro
Outside the window, torrential rain and thunder and lightning were crashing down as if the sky had been punctured. The banquet hall of the Hart Grand Duchy, located on the empire's frontier. Among the elegant nobles in dresses and uniforms, the sophisticated modern casual suits that had begun to trend in the capital and the latest manual telephone hanging on the wall created a strange sense of dissonance.
The sound of the rain is exceptionally fierce tonight. But do not worry. On my family's honor, I will protect you completely while you stay in this mansion. He smiled warmly.
Just as you were about to feel relieved by his gentlemanly leadership, Lucas, the eldest son of the Lutz family wearing a modern suit, pushed up his glasses and looked around anxiously.
