As the roots of the World Tree begin to ooze dew, the prophesied Triple Twilight is awakening. On the border of Midgard, shrouded in the shadow of Asgard, a human huntress raised by a frost giant discovered a golden ring containing divine power in the corpse of a snow wolf. At the same time, the youngest rune mage in the divine domain was exiled to the world for touching a taboo. The web of fate connects seven lives burdened with original sin: the Raven Lord who has lost his memory, the dwarf armorer who longs for revenge, the cursed giant half-blood prince, the elf female scholar who is following her father's footsteps, and the blind prophet who can hear the heartbeat of the World Tree. They meet at the edge of the broken nine realms, but they don't know whether the end point of this epic journey is to prevent the prophecy from coming true, or to become a new prologue to Ragnarok.
