This story starts with a fight Zeus vs. Prometheus. This fighting starts because Prometheus creates the humans and Zeus was very angry because he can not create any creature as perfect as humans, Prometheus created the humans. Zeus wants to destroy the creation of Prometheus because his creation was more perfect than his, the Titans. Finally, Prometheus sacrifices himself to save his creation and he receives a big punishment. But before that he creates a box, that anyone can open, and he gave Pandora this box and he said to her: do not open this box. Pandora opened for curiosity and in the box there were a lot of bad things that Prometheus closed in the box to protect his creation. And the box is called like this because she opened it.
In the world of Na’Vi it is the opposite because this world all are beautiful, magic, amazing and sparkly at night.
I think that the links in these two stories are is that in one story it is a bad thing and in the oder story it is a good thing, it is like a comparison.
