A legendary warrior known as the Harbinger emerges from myth when catastrophe threatens Urralia, a world already ravaged by the dark god Voden following the mysterious death of the priestess Vera. Armed with Omensight, a supernatural ability that allows her to relive the same day repeatedly while retaining her memories, the Harbinger anchors herself to the Tree of Life and embarks on a desperate investigation to determine who killed Vera and why. With each loop through time, she encounters four key figures—a rodentian rebel, a resolute military commander, a quick-witted performer, and an imperious ruler—each possessing crucial knowledge that draws her closer to the truth. Only by uncovering the full circumstances of Vera's death can the Harbinger hope to alter fate and prevent the world's total destruction.
