That's Ascension, actually. And its from a Goddess that was never a Primordial deity in the myths no matter who you read, who for some reason was made it for the GOW-verse, that represents the oceans/seas(which should be taken up by Oceanus and Pontus/Thalassa respectively) punching Ouranos, Kronos's father in the face.Kratos, Im a massive fan of all god of war games and getting anything close to universal requires very, very selective reading of the material. Specifically Im pretty sure most of it comes down to an explanation in god of war 1 where kronos/another titan got punched and created the stars in the sky and kratos getting scaled to that.
