The Two Knights’ Differences Collide
The “Crusadia” fellowship arrived at the place where the final battle would likely be fought. However, what awaited them was the “Orphegel Army”. The true identity of “Longirsu” is that of “Ningirsu” who severed the bonds of friendship with his former friends and disappeared with his own goals in mind. “Orphegel” is an army of machines he created to achieve his ultimate goal. The “Orphegel” continue to ceaselessly appear from “Babel” and prevent the “Crusadia” fellowship from getting any further. These two former friends now wage a fierce battle against one another.
