Celia hunts monsters for a living. Her life never had a place for politics and kings. But they find her anyway. A royal summons names her the Seven Kingdoms' next Dragon Slayer and orders her on a holy quest. She refuses at first, but it's a chance to save her dying sister with dragon's blood. Celia is not the first. Every Slayer rides through what the last one left behind. Elves gone feral after their magic was locked away by one of her predecessors. A madman chained to a tower wall, his power bleeding into the sky because a Slayer chose mercy. Every kingdom wants her to clean something up. The further she goes, the more she realizes that her actions change the world more than any dragon's. The task of a Slayer is to fix it. Or at least try. The dragon is merely an excuse. Some roles have to be filled. Monsters are made, not born.
