"Any man who takes up his sword against our enemy is a brother to me." The nation of Decoria is in shock after a decade of peace is shattered by a sudden attack on one of their cities. As the unknown enemy continues their assault, an old collective of warriors known as the Black Blades reemerge to join the battles.
The men in the collective are reclusive and ruthless warriors who have separated after many years of peace. It takes considerable effort for the current leader of the Blades, a man named Leocor, to reunite them for war.
As the war drags on and difficulties mount, Leocor realizes they cannot win this war in the traditional manner. Out of options and devoid of hope, he turns to his former mentor: an old, forgotten, and scorned warrior known as Gunther the Great. Leocor then realizes that brotherhood and faith are the only things that will save their country from the menace that they face.
