'The Smoky God, or A Voyage Journey to the Inner Earth' is a book presented as a true account written by Willis George Emerson in 1908, which describes the adventures of Olaf Jansen, a Norwegian sailor who sailed with his father through an entrance to the Earth's interior at the North Pole. For two years Jansen lived with the inhabitants of an underground network of colonies who, Emerson writes, were 12 feet tall and whose world was lit by a "smoky" central sun. Their capital city was said to be the original Garden of Eden.
