Kaelen didn't draw a sword. He closed his eyes and began to hum a melody their mother had sung—a song unique to their bloodline, a frequency no Echo could replicate.

Kaelen stood in the center of the town square, watching as the shadows of the living began to detach themselves. This was the "Soul War" the elders had whispered about—a conflict where the battlefield was the human psyche and the casualties were forgotten identities.
