Lumian did not pursue Primordial Hunger, just as he had refrained earlier from borrowing the other three powers from Eternal Darkness Amanises to try to kill Primordial Hunger in one strike. Such an action would have triggered the opponent's survival instincts, helping Him overcome His fear of "Father" and mount a strong resistance, thus exposing the deception.
Reaching this point was sufficient. By the time Primordial Hunger, a Great Old Dominator that relied primarily on instincts, figured out what had just happened and realized the falsity of "Father," hours or even days would have passed before He returned—still bearing severe injuries.
Lumian's decision was to immediately rendezvous with Eternal Darkness Amanises. Together, they would confront the already gravely injured Inextinguishable Ravings, aiming to either eliminate Him within ten seconds or inflict wounds so severe that He would no longer dare to return.
