Veins of the Titan Premise: Most worlds are built on stone and sea. Yours is built on something alive. Civilizations have grown inside a single ancient titan whose massive body forms the entire world. Cities cling to bone ridges, farmland thrives beneath the warm glow of great organs, and trade routes wind through arterial passages where rivers pulse in rhythm with something deep below. For as long as anyone can remember, the titan’s heartbeat has been steady, slow, and safe. Recently, it changed. Small tremors. A low hum felt in your teeth. Storms of strange bio-energy. Creatures acting as if guided by a new shared instinct. Scholars and shamans argue, but no one truly understands what is happening. All anyone knows is this: the titan is stirring. Whatever lies at its center, a place no one has ever reached, may soon decide the fate of everyone living inside it. Your story begins in one of the border organs, where the first signs of change have appeared. From there, the path leads deeper toward the heart of the world. The deeper you go, the stranger the rules become. This is a world where the landscape breathes with you, pushes against you, and sometimes listens.
