Many years ago, the temple-ship of the Seraphon, Wings of Serendipitous Fire, was destroyed in the skies of Shyish—not by Chaos, but by the misjudgment of Sigmar’s own servants. Now, Irixi Starseer, servant of the hieromage Sek’atta, is sent to the ancient ruins of the ship to recover a prophecy carved into its walls.

At the same time, Stormcast Vael Scar-Helm pursues the same disaster, chasing a memory that haunts him through many Reforgings. Meanwhile, the mage Perlo leads a group of Steelhelms into the area, following rumors of an unimaginable treasure.

As the forces of Order clash over the ancient power and riches of the Seraphon, an even greater, more insidious enemy emerges, threatening the very fabric of the Great Plan itself.
