The Lich Queen
D37/100Web serial by YoruTsubasa
When Sepharin K. Vrost awakens in an unfamiliar world, she's no longer the ruler of Necron's eternal night — but the Warden of a crumbling northern border in a frozen land besieged by monsters. Burdened with a new mortal body, she must wield forbidden necromancy and frost magic to resurrect the fallen as undead soldiers. Her people despise her methods, and her estranged brother demands she relinquish her power. Sepharin has only one option: conquer death itself and defend her realm. After all, true queens never rest in peace. In the second arc, as she enters the Tomb of the Dread Empress, war with the orcs reaches its climax and long-imprisoned powers break free. Inheriting a Dreadworking Stronghold sets Sepharin on the path of rebuilding her legion — machinery capable of levelling cities, flying towers, and beacons that illuminate the frozen skies. But old forgotten souls stir in the deepest dark, and the powers ruling the world have begun to notice.
