Soul Wars by Josh Reynolds was published in 2018 as the flagship novel for the second edition of Warhammer Age of Sigmar, and it carries the weight of that role well. Where many launch tie-ins settle for spectacle, Reynolds uses the outbreak of the Soul Wars — Nagash's great reckoning against Sigmar for the souls the God-King has claimed for his Stormcast Eternals — to ask the setting's most uncomfortable question out loud: if both gods harvest the dead for their armies, what actually separates them?
The story centres on Glymmsforge, a fortress-city of the faithful in Shyish, the Realm of Death, built above a vault of sealed tombs. When Nagash's Necroquake convulses the realms and the amethyst dead rise everywhere at once, the city becomes the front line. Reynolds splits his narrative between two soldiers of Azyr whose fates diverge in the cataclysm: Balthas Arum, a scholarly Lord-Arcanum of the Anvils of the Heldenhammer sent to hold the city, and Pharus Thaum, a devoted guardian of Glymmsforge's tombs whose soul is torn away from Sigmar's forges and remade by Nagash into something spectral and vengeful. Their mirrored journeys — one descending from the heavens, one dragged into undeath — give the war a human spine, while Lady Olynder, the Mortarch of Grief, arrives as the terrifying public face of the Nighthaunt procession.
The novel matters because it defined how a whole phase of the setting felt. The Nighthaunt as an army of weaponised despair, the mechanics and costs of Stormcast Reforging, the sense that Shyish is contested ground rather than mere backdrop — all of it is dramatised here first and echoed through later fiction. For readers building a path into Age of Sigmar prose, Soul Wars remains one of the natural starting points: a self-contained war story that also happens to explain why the Mortal Realms' second act is a war over souls.
