In a world where humans are the leading species and the other as to retreat to the deepest part of the planet. A mission was launched... travel to those parts and conquer them... A former captain of the Special Air Service, James Conrad, was engaged to go to the deepest part of the planet, a place that the human call Pandora. It is said that whoever cross the frontier of this place will never come back, for all who stepped foot here disappear without any signs. But... was it because it was too dangerous ? Or because humans were the danger to those who lived there ?
