In the game you play as a mysterious man who is able to die but won't grow old.
If you are able to survive you can observe and shape the Fleeting Ages as they pass by. You are the only one of your kind and there are no other supernatural beings in this world.
Find your own role in this world as your actions change your world for the better or worse. You can affect the world by inventing tools and weapons never seen before. The changes you make in the world as little as killing an animal to as big as building a town will be permanent.
