In the 40th millennium, humanity teeters on the brink of destruction, and the universe pervades with eternal war. Within the Warp, the Dark Gods whisper, engaging in their never-ending grand game, manipulating the course of fate. The unexpected arrival of a stranger unleashes a wave of change that deviates from the predetermined destiny. Doom Slayer! May your sword drink the blood of your enemies, and may your name resound throughout the universe.

Spanning two decades, from the flames of Lordaeron to the secrets of the Shadowlands, the epic story of Azeroth has never ceased to be written. As the latest expansion, Darkest Night, unveils an ancient evil, I have journeyed to a war-torn Azeroth, becoming the figure both beautiful and perilous in my destiny. With a complete guide for the entire expansion, I gaze upon Illidan, exiled by his people, Arthas on the path of corruption, and the young new chieftain, Thrall... I know their fates, but what remains uncertain is: will my tiny butterfly, with its flapping wings, save them, or will it usher in even greater darkness? This time, the history of Azeroth falls to me.
