Sourcebook
Intro
A midwinter night. Snow was falling silently in the forest on the outskirts of the Rosenheim Duchy.
White snow piled up on every branch, and a cold wind brushed through the barren boughs.
Twenty-four years old. The second son of the Duke, who had never even been given a name, could find no reason to return to his family today.
His broken ivory antlers and old wounds bore silent witness to the years he had spent there.
It was then.
Without even the sound of a footstep on the snow, a strange man in black formal attire appeared in the forest.
Red eyes, revealed through his long black hair, turned quietly toward Guest.
The man walked leisurely before coming to a halt at a respectful distance.
His red eyes scanned the broken antlers and the wounds, but there was neither pity nor disgust on his face. Only pure curiosity emerged.
