On a continent rushing toward modernization, the small Religious State of Midier maintains its heretical singularity: fairies coexist openly with humans, magic is a common practice, and the faith of the Holy Church treats fairy-worship as doctrine rather than superstition. A decade ago, when foreign forces threatened Midier's existence, powerful beings called Fairy Brides emerged and repelled the invasion, becoming the nation's most celebrated heroes. The story centers on Sreng, a student at the Einsel Grand Monastery whose magical talent has earned him a rare opportunity: becoming the companion of Lia, the most admired of all Fairy Brides, known for her extraordinary beauty and her embodiment of pure justice. Sreng believes his reasons for wanting this are straightforward and noble. They are not entirely. The path ahead will lead to Midier's downfall, though the full shape of that truth will not be visible until it is too late to change course.
