Xena Wearing the Helmet of Hermes
The Helmet of Hermes is a magic helmet that belonged to the god Hermes. It gives whoever wears it, and whoever the wearer is touching, the power of flight. Hermes was never shown in XWP even though he was brought up a few times. He also wasn't killed during the Twilight of the Gods.
It was only seen once in the epiosde Many Happy Returns. Xena and Gabrielle were taking the helmet to Thebes, where it finally ended up, after it was stolen by the warlord Ferragus. Why Hermes didn't have the helmet anymore was never said, or why it was being brought to Thebes.
Xena also used the helmet to save a virgin sacrifice named Genia, and to fly with Gabrielle as part of a birthday treat.
