For 312 years the rotstorm has blighted the ruins of the Ferron Empire.

Born of an unholy war between gods themselves, it scours the land with acid mists and deadly lightning, spawning twisted monstrosities from its nightmarish depths.

On the Stormwall, the men and women of the Stormguard maintain their vigil - eyes sharp, blades sharper - defending the Undal Protectorate from the worst of the rotstorm's corruption.

But behind the storm front, something is stirring, kindling the embers of an ancient conflict and a plan to kill a god.

Will Stormguard steel be enough to meet the coming tempest?

---

Floré returns to the Undal Protectorate to find it blighted by the deadly ice and bitter winds of a Claw Winter. Her people are dying, and she is sworn to save them... but she can think only of her daughter Marta, slowly succumbing to her skein-sickness, trapped somewhere in the far, far north.

Now Tullen One-Eye - the man they call the 'Deathless' - has been freed and roams the land once more. There are rumours that the great god-wolf Lothal hunts again. And, deep in Orubor's Wood, the god-bear Anshuka stirs from her slumber...

Floré must raise her gauntlet one final time if she is to save her daughter and her people. But will steel alone be enough to take down the gods?
