A few years ago, at Olympus
Kratos angrily confronted Athena about the power of hope that surrounded him to kill Zeus, who was corrupted with the power of fear and caused him to be consumed by it. Unsettling of all was that Kratos would never willingly give the blade to Athena, as the key to spread hope throughout Olympus.
"My vengeance ends now." Kratos said with a finality. He took the blade and pointed it threateningly towards the corporeal form of Athena. He then proceeded to swing it towards Athena in a fit of rage.
"You dare to strike me that again?!" Athena then retorted angrily. Kratos swung the blade towards Athena, then it phased out and aimed it towards him.
His hands held the blade and proceeded to stab himself in the chest. Blood then spewed out amidst Kratos's chest and slowly fell down before Athena reprimanded Kratos. After he stabbed himself, a blue energy released through his body. Hope. All the powers he took from Pandora's box few years ago was released from his broken body.
"You fool! What have you done?!" The blade continued to dig into his chest until he finally gave up. Athena then approached Kratos with a stern look on her face.
"How can I use the power of HOPE?! I am disappointed you die in such way cowards do." Athena took the blade from Kratos, which it was already useless, and disposed of it before she disappeared.
Ruins of Olympus, a few years later...
All of Olympus was deserted and destroyed. Not a fleck of a human to be seen nor the gods or titans. Just emptiness, alongside condemned buildings. Moss and vine settled into each square mile of buildings. The whole place was extremely barren, with no flora and fauna appearing, save for the passing birds. Rain never appeared, but eternal sunlight, since Kratos's death and literally every structure after structure was slowly collapsing.
At the top of the abandoned and destroyed rotunda, a lone soul was floating into the sights of the broken city.
"Such destruction Kratos had wrought," said the soul before revealing as Zeus, "that petulant, murderous fool wanted his revenge, only to destroy the whole city!" Zeus then hovered towards the edge of the rotunda, looking through traces of destruction the warrior has caused.
Anger began to fume from his soul's body, as the thunderclouds began to emerge. Lightning bolts crackled violently as torrential downpour flooded the ruined city. Zeus then began to absorb the power from the clouds, as his body and powers began to materialize once again.
"There is no way I will give up. I have my powers back and find another world to make a new Olympus, the new one that the ignorant fool like Kratos will never touch or even destroy with his merciless hands!" Hopeless of renewing Olympus, Zeus then channeled a powerful stream of vortex, creating a portal from an unknown dimension.
"Only fools will never underestimate me!" Loud laughter began to form around Zeus as he entered the vortex, disappearing from the ruined city.
