The beast had grown, and its taste was no longer limited to waiting for the dead to decay, with Rowan's unceasing draining of the vitality it exuded, the appetite of the creature exploded. No longer a carrion it became a hunter. To sustain its size which was increasing daily, it needed nourishment.
With its great size which was currently three times bigger than the rest, the beast claimed all the corpses in the area for itself, and for a while, it reigned over this area, but its appetite never diminished but continued growing, and soon its existence could no longer be tolerated by the others.
One by one the others began to attack the ravenous beast, but its size had granted it great strength and it easily overcame the opposition and devoured them, not even waiting for them to decay, because it knew it was now somehow capable of eating all the death energy without being poisoned by life.
