Immortal Plague

The concept of a disease that grants immortality is so intriguing and dark. I wonder what sparked the idea to explore this theme within a historical fantasy setting?

The story’s tension dips a bit when focusing on power struggles, but it also adds depth. Was that deliberate to build atmosphere or a natural flow of the narrative?

The world-building feels rich and immersive. I'm curious whether a detailed history influenced the fantasy aspects or if they evolved alongside each other.
