After suffering exile from his tribe and beginning a journey based on a prophecy he barely understands, Nox ventures into the desert, guided by Shakashai's training and hunted by shadows he cannot yet see. Joined by the fierce and loyal assassin It'xelo and the determined desert elf Kaia, Nox heads to the desert fortress where the forces of the serpent banner have gathered. Meanwhile, the sorcerer S'ekar plans for a magical ritual capable of reshaping the world, all while haunted by his own dark past. As prophecy and conspiracy converge, Nox must face not only the enemies before him, but the unsettling possibility that the "serpent" he is destined to face may be far more than a single creature. In a realm on the brink of twilight, every decision made could either save Annarheimur or doom it to eternal night.
