War Song of the Mirror Realm

When Adrian von Rhein, a bronze-mirror researcher at Oxford University, is reborn on the continent of Florence, he brings with him not only memories of being betrayed by the Church and dying a gruesome death in his previous life, but also awakens the mysterious "Dawn Manor System." By developing his territory and advancing agriculture, he can earn fragments of ancient magical cores and long-lost magical techniques. The heirloom mirror he carries can still reveal the past of any object, but he has yet to realize that it and the ancient Greek bronze mirror in an Earth museum are a pair of "twin mirrors" spanning time and space. The twelve lunar-phase patterns correspond to the twelve magical cores that control the world's very foundations.

Selina Nightblade, an elven ranger from the northern forests, carries the weight of her people's extermination and writes her own laws of survival on the border with a dagger made of beast bone. Lucas Ash, a former paladin of the Holy Temple, wanders under a curse of holy fire, searching for evidence of the Church's crimes amid the explosions of alchemy. Reborn, Adrian uses a thousand years of agricultural knowledge from Earth and modern management principles to spark a wave of reforms in the Silvermoon County: He uses crossbreeding to cultivate frost-resistant wheat, builds steam-powered mills, and turns abandoned mines into magical crystal nurseries. When an orc tribe launches a surprise attack with frost-wolf magic cores, and the Church's conspiracy gradually comes to light, Adrian must use the power of the mirror realm to uncover the truth buried for a thousand years. He must also use his farming System to turn his territory into an impregnable "Dawn Fortress" and lead his allies in changing a fate ruled by evil gods.

"In this life, I will let the radiance of the twin mirrors light the way to a future for all the oppressed!"
