Athen was once a human in the service the now deceased Republic of Man. On a mission of exploration, he came into contact with Culmination, making him the first human to do so. At that point he abandoned most of his humanity and attempted to save all the remaining members of his team from a horrible alien life form leftover on the abandoned city-world. He was only able to save Sven, as the others died quickly at the hands of the creatures. Thus Athen left that world and encountered the Extemos for the first time. He quickly realized the extent of the threat they posed to the entire galaxy and set out to save the remaining sentient races from the encroaching darkness.
