God of War can not be said to follow the original mythos word for word, but it has definitely taken mythology as inspiration and breathed new life into those ancient stories of wonder and might.
In lieu of the new logo that was announced for the upcoming God of War installment, one can't help but wonder what awaits us in it, storywise.
The God of War franchise has, at first, started off as a standalone game. Due to its high success, and foundations made in popular mythology, the universe was expanded upon. In the most recent God of War game, we find Kratos to be living a humble life, away from civilization with his son Atreus.
Later in the game, we find out that the Ice Giants' name for Atreus is, in fact, Loki. According to mythology, Loki is the adopted son of Odin, raised alongside Thor, and the one responsible for the cause of Ragnarok. Of course, with creative liberties in place, in God of War, Loki's parentage is a bit more complicated. His mother is, just as in Norse mythos, Ice Giantess Laufey, whilst his father is the Ghost of Sparta.
As we've had dealings with Jormungandr, the Midgard serpent, it is safe to assume that Fenrir and Hela exist as well, despite all three of them being his children in the original mythos.
Taking into account the possible foreshadowing with the Greek choice of name, Atreus, the story may be more than just a bloodbath before the end of the world. Atreus, in Greek mythology, is exiled from his home due to his pretensions on the throne of Olympus, who goes on to becomes a king of a neighboring country. What can be assumed is that, we will be visiting Hel once again, searching for allies in the form of Hela, the goddess of death, and explore the world looking for Fenrir, the Great White Wolf, and of course, summon and nurse to health their current ally Jormungandr, and wage battle on the oppressive rule of Odin.
Alongside them, the battle for Asgard may begin, one reminiscent of the battle for Olympus. However, due to the meddling of foreign elements, and Atreus' greek name, Ragnarok may not be as destructive as it is in the original Mythos.
Even with the creative liberties taken by the creators, one fact remains though, Greek pantheon is supposed to be immortal, while the Norse pantheon has an end in their own stories. Kratos killing the immortal gods does not bode well for the "mortal" ones, especially when the name of the game itself spells their demise. And with every logo bearing Ouroboros, the serpent of looping time, history will likely repeat itself.
