When the World Shook

Three adventurers find an ancient crystal tomb on a South Sea island, revealing two Atlanteans who have been in suspended animation for 250,000 years. One of them, Lord Oro, is the last of an advanced race that once dominated the planet, along with his daughter Yva, the heir to the Queenship of Earth. Disillusioned with the world of the early 20th century, Oro plans to use his technology to reshape human history by creating a new beginning for the planet.
