"You and I, we're bound by that thread of fate. Destined to fight." Ghirahim spoke these words. Demise's sword was thrown in prison soon after the defeat of his master. The humanoid object was cursed by the hero; cursed to remain alive until he atoned for his crimes. In return, Ghirahim did the same. Link cannot break his curse without helping Ghirahim break his. A life you have forever loses its value after a while.
