Witch King. Wiedźmi król

The setting feels so richly detailed and immersive. I'm curious whether the author crafted the lore first or let it develop organically during writing.

His morally gray actions made me question whether he's truly the villain or a product of his circumstances. How did others interpret his motives?

The internal conflict added so much depth to his character. I wonder if this was planned from the start or developed through the writing process.
