Hades does not like his grandmother at all. It is not enough that she is one of Olympus greatest enemy, she is also very capable, cunning and at times straight up evil.
Probably right now, she is laughing in her hideout or something, looking at the chaos that is happening in Olympus.
"How similar it is today" Hades thought to himself.
"Let's go in" Hades just nods and the giants opens up the door of Tartarus. The creaking sound of the door seems to shake all the land
In the surface world, the realms under the control of the Olympians all shakes.
But now with war being waged between the gods, none of them could sense this subtle energy of the dead
Of bloodlust.
Of destruction that is seeping out from Tartarus and begins influencing the reality of this Universe
Even Osiris and Ra did not notice it
The door was opened
Poseidon see the door but as the door opens, he did not see it. And then he was already inside.
