Ceiba was a lost city in the Amazon region built by wayward Celts looking for their old homeland, Atlantis. It was also known as the Lost City of Z, after the British isle of Zealand. In 1925, Colonel Percy Fawcett set off into the jungle looking for it. He was rescued the next year from the city's people by Doctor Indiana Jones, but died along with Mrs. Jones in a plane crash on the return trip.
