Four riders of legend that represented men's worst enemies; Famine, Pestilence, War, and Death. Shadowen in their guise were sent to Paranor to imprison Walker Boh. Walker attempts to slip past unseen but is discovered and even with his newfound powers is unable to defeat them and barely escapes. He comes up with a plan to defeat them and goes outside to fight them in the middle of the day. He uses illusion to turn their attacks against each other, destroying all except Death. Cogline comes out of the Keep and throws himself in between Walker and Death and is mortally wounded. An enraged Walker destroys the final horseman by driving Druid Fire into its hood and burning out its soul.
