Disclaimer: I do not own these characters, these are owned by Santa Monica Studios and my original characters in this fanfiction aren't canon. This fanfiction is some sort of a "what if?" and an after situation in the God of War game series that takes place in the Greek Pantheon. What happens to Ancient Greece after the Second Great War? What if Aphrodite and Kratos had a son and was conceived after the happenings? What if the Spartans and the remaining Olympian Gods finds out about it? What if Mount Olympus and the remaining parts of Ancient Greece were rebuilt led by Athena after the death of Zeus and foresees a prophecy from the child of Aphrodite from Kratos? The one that could only answer Spartan-Olympian Demi-god who happens to be Aphrodite's child to the fallen Ghost of Sparta and the one who dethroned Ares from being the God of War, Kratos.
