In the Echo Age, where sound carves boulders and faith determines gravity, retired Godslayer Thunderstone just wants to bake bread in peace. Until one day, the whole world forgot about him, and a storm with intelligence began to chase this "non-existent" person across the continent. Thunder Stone must prove that the law of gravity is wrong. Not only is this his only weapon against natural disasters, but it will also reveal a shocking truth: What he is resisting may be the last lie the world relies on to survive.
