The time approaches for Zeus to face his father.
The end of an entire age is approaching rapidly now. The Golden Age was marked by the peaceful rule of the Titans. Despite the madness of Cronus, this had little effect on the world at large. His outbursts and paranoia were directed mostly at the other Titans and particularly his own immediate family. Now war approaches between him and his son.
Zeus is ready to make the first move, poisoning the wine.
