Godeater's Son - Warhammer. Age of Sigmar

This is a Mortal Realms story with a twist a virtuous man succumbs to the path of darkness, and wages a war against Sigmar. Heldanarr Fall dreams of a world without gods. When the Azyrites descended upon the Burning Valley a kingdom carved from the Aqshian desert they brought arrogance and cruelty with their riches, and a god who seemed blind to it all. Despite harrowing losses, Held clung to his peoples ways, forging a new existence without a single prayer to the armoured deity, Sigmar. Now, all Held wants is solitude. But after saving a Sigmarite priestess from violent death, her troubles catch up to them and destroy the last of his peace. First broken, then enraged, he launches a brutal war of vengeance against Sigmars worshippers, and soon finds himself thrust against the Stormcast Eternals, led by the cunning strategist Ildrid Stormsworn. Alone, he cannot hope to win, yet surrender would mean accepting the mercy of a god he despises. To defeat the Stormcasts and avenge his fate, Held must embrace older, darker powers that risk the very freedom for which he fights. But when Sigmars rulers are tyrants and the Champions of Chaos prove worthy, which path is the most righteous? And once this choice is made, who will Heldanarr Fall become?
