Beneath the cracked bones of the Earth lies Derinkuyu, a once-great subterranean refuge now buckling under the weight of fear, scarcity, and secrets. Ayla, trained since childhood to preserve the old ways, feels the pressure mounting—not just in crumbling stone and dwindling supplies, but in the eyes of her people.

When a long-buried prophecy points to renewal on the surface, Ayla finds herself torn between the old world's rituals and the promise of something new. With a loyal few at her side—including warriors, scholars, and dreamers—she must brave betrayal, disease, and the long dark climb to the future.
