Steve was the only Stormcloak Soldier in Vahl's Command, until he died on the final battle for the Stormcloaks.
He died on the final battle for the Stormcloaks, his death did make sense, because it was the FINAL battle of the Stormcloaks. In a movie death it would take place in the FINAL battle. His body was never found after the battle. He died with a Minecraft Dog.
