Note on Process & Accuracy: Every story on this channel begins with a deep respect for history. I act as director and editor, using AI tools to help research and draft the script while I 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. 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.
