The Zenith isn't just a skyscraper; it's a monument to human ambition, a gleaming spear of glass and steel piercing the heart of the city. But on a seemingly ordinary Friday, its perfect facade shatters. All communication dies. All exits seal. And then, the screams begin – not from people, but from the very structure of the building itself.

An ancient, primal entity, long dormant beneath the city's foundations, has awakened. It is "The Rooted Silence," a vengeful spirit of the earth, manifesting as a creeping, consuming growth that devours sound, light, and life, leaving only petrified husks in its wake. As the high-rise transforms into a vertical tomb, its trapped residents, products of a world built on noise and technology, find their modern solutions useless against a horror that defies all logic.

Their only hope lies with Morwenna Albright, an eccentric elderly woman whose forgotten wisdom and unsettling connection to the land offer a terrifying path through the deepening darkness. But Morwenna's guidance comes at a price, forcing them to confront not just a monstrous entity, but the very arrogance of human progress and the chilling truth that the earth remembers.
