“So, boy. You wish to serve me?” Silhouetted against the blue-black sky, the horse-mounted samurai with the horned helmet towered over me like a demon as I knelt in the dirt before him. I could not see his face but there was no mistaking the authority in his growling tone, nor the hint of mockery in his question. I tried to speak and managed only a faint croak.
