In Rise of the Deep: The Creatures attach earth from within, the oceans and from the sky.  Ancient creatures long hidden beneath the Earth’s surface, known as the Dwellers, begin to emerge, intent on reclaiming the world they once ruled. These intelligent and powerful beings, forgotten by history, are driven by a centuries-old conflict with humanity. As they invade cities and towns across the globe, the balance between the surface world and the underworld is thrown into chaos.

The story follows a group of unexpected heroes who are drawn together by mysterious forces to combat the rising threat. They are guided by a stranger with knowledge of the Dwellers' history and their goals, the heroes must learn to navigate the surface, the depths of the Earth, the Oceans and Skies. Along the way, they uncover an ancient energy source called the Life Core, which sustains both realms. If the Dwellers gain control of it, they can reshape the surface world, leading to humanity's destruction.
