2411 - A date that will remain in people's memories because that year will mark the beginning of the first upheavals, both on Earth and on Terra One, their host planet. It is the story of two different human worlds and four allied races: together, they will see the fifth race born! On July 20, 1969, Neil Armstrong walked on the moon. On December 8, 2186, Paul Tenara on Mars. The man was not ready to discover the secrets of Mars. Their ambitions to create androids from an unknown ore turned against them. These machines had decided to exterminate all Earth species. Their goals: to reclaim the ore that men had sent to Earth, leaving ruins for humans. For nearly two centuries, men fought for the survival of the human race and only one of them managed to find their weakness: Victor Messan. The story of the Forgotten begins in 2411, when the Second Chance shuttle lands on Terra One, their host planet.
