In 1913, guided by the "Ponape Script", Harold Hadley Copeland led an expedition into Indochina to locate the plateau of Tsang and to find the tomb of Zanthu. After the other members of the expedition died or deserted him, Copeland pressed on, eventually reaching his goal. Opening the tomb, he was horrified to discover that the mummified face of Zanthu resembled his own. Later wandering into a Mongolian outpost, a starving and raving Copeland was the only survivor of the expedition.
