It has been a week now since Rhea, her sisters, her niece and nephews and her children arrived at Mt. Olympus and during the course of that week, Rhea and her children have bonded and she gets to name them.
She named her eldest daughter and firstborn, Hestia, her second born, Hades, the third, Demeter, the fourth, Hera and the fifth, Poseidon.
The six siblings also became closer with Zeus telling them about his early life and how it was his mission to usurp their father, Chronos to which they all agreed.
Now today, the three boys of Rhea, Zeus, Hades and Poseidon are about to venture into Tartarus, the domain of the Thanatos and two Primordial gods, Nyx and Erebus to rescue the Hekatonkheires and the Cyclopes and in the process, send a message to Chronos.
