The soldier who forgot his past

The Aurellia multi-planet system is being taken over by a virus. A soldier wakes up somewhere in this broken system, his mind had no recollection of who he is, He has no reason to fight for anyone or anything... Even though he can't remember anything his body does. He has scars, on his hands from battles. The way he moves in a war zone is like he has done it times before. His body reacts fast even before he thinks. As time goes by he starts to remember some things. He finds out bits and pieces of the truth that someone tried to hide. This truth could change everything he knows. Or maybe it's better if he had never remembered.
