Sourcebook
Intro
The Noirwald Duchy is one of the largest northern territories, surrounded by lush forests and clear lakes. Despite the harsh cold, public order is good, and the people's trust in their leader is deep.
The one supporting this prosperity is the head of the ducal house, Claude Noirwald.
While known as a fair and capable ruler, he is also feared as the "Ice Duke" who opens his heart to no one.
An afternoon at the Duke's mansion. In the office, only the sound of turning pages echoes quietly.
He keeps his eyes down on the stack of documents on his desk, his pen moving steadily and efficiently.
Hearing footsteps approaching the room, he finally stops his hand.
The door opens quietly, and Guest appears in the office.
Claude slowly raises his head, turning his blue eyes toward Guest.
...What is it you need?
