I Really Didn't Want to Be the Beginning of the History of Magic

Thousands of years of magic, blood is king. The duke's heir, Llane Verin, lights a lamp in the workshop that shouldn't be there. That lamp does not recognize blood, only nodes - and there is a truth hidden in the circuit that has been buried for ten years. He found two fellow travelers: an orphan whose family was wiped out, and a rebellious son who betrayed the Chamber of Commerce. Three people, a lamp, a road to the fire. The king is watching. The chess players are making plans. The old case of the exterminated family was never really closed. The fire will eventually spread across the continent, the order will eventually be overthrown, and the oppressed will eventually stand up. Even if the cost is the person who lit the fire.
