From the Netflix series Blood of Zeus (which I have just started watching)

Set in the first few episodes in S2.

Zeus is dead, defeated in battle against the re-released Giants and the entirety of Olympus will now have three days to mourn their fallen King. Until a fit heir is chosen, Poseidon is temporary at the ruler's throne.

But things shift in the shadows, rumors, murmurs. It's only a question of time... but who strikes first?

Will Hera try for the throne again? Will she aid Ares? Or will Hades at long last try and grasp for more than the gloom and doom of the Underworld.
