We act as directors and editors, using AI tools to help research and draft the script while we shape the narrative and verify facts. The narration comes from a digital replica of a professional voice actor, and the images are individually crafted artistic impressions using AI. Even with these tools, creating a story of this depth still takes hours of work. Please note that while the narrative is thoroughly based on historical research, its primary purpose is storytelling for entertainment and relaxation. As such, it is not intended to be used as a formal academic or scientific source. Thank you for your trust and support.
