It was the night of the Third Caer'Nam Cycle when the bells atop the Monastery of Aeol Drias rang, alerting its residents about the huge Knights of the Fold army marching towards its gates. The Preceptors gathered every available student to man the walls of the fortress while preparing the rites of subjugation and handing scrolls of magical potency. Some of the Preceptors foreshadowed the fall of their order on that night, with blasphemous words gliding off their tongue - until Nortrom sliced them off. He appeared wearing an armor of unknown origin, ornate with powerful sapphire gems that radiated with calmness. The glaive in his hand oscillated with unfathomable energies, their source being the infinite wisdom of Aeol Drias' prophesized Champion. He ordered the students and Preceptors to stay back from the walls and let him handle the trespassers on their sacred land. The Monastery Elders were in outrage, trying to reason with what was their only hope of safeguarding the legacy of their order if things turned for the worse in the stalwart defense of their homeland - but were blessed with the gifts of silence, though only until Nortrom has finished with Chen and his lackeys. The Knights of the Fold besieged the Fortress-Monastery of Aeol Drias, demanding heads of the Elders and the immediate surrender of its remaining residents. The answer to their conditions came in the form of Silencer, walking in steady pace towards the massive army under the banner of the Fold. Chen rode forth to meet the so-called "champion" of his sworn enemies, but was stopped in his tracks when the glaive flew before him, nearly slicing the head off his shoulders before returning to its owner's hand. Proclaiming this assault as the act of hostility, Chen ordered his army to march forth and take Aeol Drias in the name of the Fold.
However, as soon as Nortrom uttered the Curse of the Silent his adversaries began screaming in pain and agony as the piercing light of the sapphire gems burned their very sight and sanity, reducing the army to bunch of demented beings unworthy of calling themselves "humans", let alone the Knights of the Fold. Horrified with what he has witnessed, Chen tried to redeem his fellow warriors in the eyes of their ever-present God, but found himself unable to utter the prayer for he felt it would be his last word while standing before his nemesis - so he turned back and rode fast on his trusted locuthi while the still-conscious remnants of his army dragged their weakened bodies away from the gates of Monastery. Having fulfilled his obligation, the Silencer went back into the fortress, inside which he was being questioned by the Elders about the outcome of his confrontation with the Knights of the Fold. Nortrom remained silent, but the gems on his armor beamed-out towards the walls, as if trying to say something to the members of the Order. Rushing to the walls, they stood in shock and awe, silent as the bodies of their enemies, broken in form and drained of spirit, lied on the sands, making a circular pattern inside which a three-eyed visage with sewn mouth could be seen - an omen that warned of the powerful curse that was uttered on that grim day in the history of the Knights of the Fold...
