Was there a demon or devil on Star Trek named Audra?

Answer 1

Ardra, not AudraArdra was the name of a mythic figure who supposedly returned to Ventax to fulfill a thousand-year-old contract with the Ventaxians in an installment of Star Trek: The Next Generation,Season 4, Episode 13, called "Devil's Due."

In reality, however, as the Enterprise's personnel eventually revealed to the Ventaxians, the identity of Ardra was part of a ruse that an all-too-human, and all-too-mortal, confidence artist (whose real name was never revealed in the installment) was using. Having been operating from aboard a ship that proved to be equipped with a bad copy of a Romulan cloaking device and and having been conducting her petty schemes for years, she was, according to her crew, known by at least ten distinct aliases (if not more) in that sector alone.
