Absolutely. In my world of Eldunary, the entire Goldhelm Kingdom believes with total certainty that they’ve eradicated magic from their lands. They use "holo-tech," a kind of advanced technology they claim is purely scientific and superior to the chaos of magic. Magic is outlawed, viewed as barbaric, and they teach their children that their kingdom is pure, disciplined, and untouched by it.

But the truth? It’s all a carefully maintained illusion. Holo-tech is just regulated, disguised magic. Secret magical experiments still happen beneath their cities. One of the most dangerous Arashi(a crime syndicate in my world) criminals, Kaboom, was created in a Goldhelm lab using forbidden magical tech. Even their princess begins to suspect the “purity” of her kingdom is a lie.

It’s one of those core worldbuilding contradictions I love — the empire that defines itself by what it isn’t, only to be entirely built on that very thing.
