We work as directors and editors, using AI tools to assist with research and drafting the script while we shape the narrative and verify the facts. The narration is delivered by a digital replica of a professional voice actor, and the visuals are individually crafted artistic impressions created with AI. Even with these tools, bringing a story of this depth to life takes many hours of work. Please keep in mind that while the narrative is grounded in thorough historical research, its main purpose is storytelling for entertainment and relaxation. It is not meant to serve as a formal academic or scientific source. Thank you for your trust and support.
