The world as they know it is gone. All of their efforts to save it had given the demon Watcher Azazel the very key he needed to bring the world to its knees. The power of the Swords of Valor is exhausted. The quantum computer, key to their operations, was malfunctioning. The Gray Champion had been struck down by Azazel, and the quantum essence of their grandmother had been cruelly abducted. Power to the Keeping Room had failed, plunging them into a darkness that flooded not only the eyes, but the soul, while the world above them burned. Despair, hopelessness, and uncertainty were all that remained in the hearts of the once-courageous Guardians.

In the depths of their bitterest defeat, a Teacher comes to them, offering guidance shrouded in mystery. The robed, enigmatic figure may be their only hope to save their grandmother, and the world, but none of them are certain this Teacher can be trusted. Deception is the most powerful tool in the arsenal of their enemy, and this, too, could be nothing more than a demonic game to lead them to further despair. Journeying one last time through history, they must seek their ancestor and originator of their line of the Guardians of the Swords of Valor, Joseph of Arimathea. Only through him can they find the holy relics needed to defeat Azazel once and for all; the Stone of Jacob, the Holy Grail, and the mythical Sword Above All.

Under the eyes of the archangels themselves, face to face against the Watcher Azazel, the Guardians must wage the final battle against evil. Victory is their only option, for there will be no second chance in this ultimate confrontation. The salvation of all mankind rests in their hands.
