one of the failrues especially of the codexs in 40k is to show the importace of worlds such a agri-worlds. agri-worlds while not in the trillions, do have populations in the hundreds of millions to upper billions, along with the life-blood of all their life-stock. without a nearby agri-world most hive-worlds end up dead of starvatoin within a short period of time. There is more than enough blood to be had both literal and metiphoical on a agri-world to satisfy khone, actually to the more advanced servents of the blood god, a sacrifice of a planet is a greater blood sacrifice than a whole army.
