Samurai Jack - Samurai Jack AU- Paladin Aku

This was probably the story the High Priestess told Ashi and her sisters.

Fifty years have passed, but… I do not age. Time has lost its effect on me. Yet, the suffering continues. The samurai's grasp chokes the past, present… and future. Hope is lost. Gotta get back -- back to the past… Paladin Aku.
