Aysén, a region of Chilean Patagonia, is about the size of England, but has just ninety thousand inhabitants. They live isolated, almost without roads, in a dazzling, rugged, violent landscape. In some corner of this lost world, a mysterious city hides. Five hundred years ago, a group of conquistadores built La Ciudad de Oro. They are still alive. Whoever enters there becomes immortal, but loses his memory. It's the City of the Lost Caesars, and you've come to find it.
