Well, without more details about the 'ares short story', it's hard to be precise. But if we consider a modern - day take on an Ares short story, it could be about a young archaeologist who discovers an ancient artifact related to Ares. As he delves deeper into its secrets, he starts to experience strange visions of battles from the past. He soon realizes that the power of Ares is somehow still lingering in the artifact, and he has to figure out how to deal with it, either by using it for good or making sure it doesn't cause any harm in the modern world.
