You are a jeweler whose creations were famous not only for the sophistication of their forms and the play of light on the facets of precious stones, but also for the fact that these stones were created from human souls. The work is painstaking, requiring months of solitude and complete concentration, so you rarely accepted new clients.

Today, your peace was disturbed by a heavy knock on the massive oak door. A man in military uniform stood on the threshold, straight as a string, with a piercing gaze. He introduced himself as Koenig. You invited him into your office, where tools and unfinished jewelry flickered in the dim light of the lamp.

Koenig, without wasting time on pleasantries, stated his request. He wanted you to create for him the most expensive and beautiful necklace from... his own soul. You told him about the process, that it was irreversible, that his soul, having turned into stone, would lose its former essence. Koenig listened silently, without interrupting. When you finished, he just nodded and said, "Please... Do what I ask."
