Timeshift

A deluge of rain and a strange hitchhiker combine to transport martial arts champion Noah King on a bizarre course to an alternate world. Days whiz by in a fraction of a second when he enters a mysterious fog. His passenger, Sylv, is not what she seems. She admits to being a Tabizi, the instigator of his fog-encased journey to World 5. She has chosen him to intervene in the anarchy of a split world two hundred years in the future. Time reversal fails, and Sylv is stranded with Noah. She deserts him in the forest, and becomes known as Dark Seeress. Noah discovers he must fight the anarchist leader in blood sport to survive. After he defeats his opponent, an influential dwarf proclaims him the new king. Captive women flee to the forest, where Sylv declares all women are under her protection. Noah learns this world was split by quakes and volcanic action that left a 100 meter high Great Wall circling the globe. Cannibals roam the Wasteland on one side, preying on refugees. War is imperative to keep the savages out of Noah's lush green kingdom, but Sylv refuses to ally herself and the other women with his forces.
