The Jaws of Cerebus tap into the geo-thermal energies of a planet to power the massive graviton generators of the Jaws system. Once fully powered the Jaws generate a field that can radiate out increasing the host planets gravitational field enabling it to expand outward grabbing any and all objects in the near vicinity. Once trapped in the gravitational field there is no escape and anything trapped in the field is dragged down to their doom in an uncontrolled descent to the planet’s surface.
