Acheron had already appeared behind Edward.
The movement was silent, instant, and deadly. One moment the space behind Edward was empty, and in the next, it was filled by a towering spectral knight. Acheron's massive greatsword was already raised high above his head, blue shadows crackling violently along the blade. The indigo aura around his form surged outward in waves, distorting the air as the weapon prepared to fall. There was no hesitation in the strike. A clean execution, driven by overwhelming power.
Then Edward vanished.
The world twisted for a fraction of a second. Space folded inward, and Edward reappeared behind Acheron just as smoothly as he had left. His sword was already in motion, cutting forward with perfect timing.
Their blades met.
Clang!
