Despite it's name, the New Moon of Delvia is not a moon but a planet in and of itself, located within the Uncharted Territories. It was uninhabited, due largely to a harsh and barren climate. Eventually, a group of Delvians practicing the Delvian Seek crashed upon the planet. They named the planet after the spacefaring Delvian temple which they had traveled in, and constructed a small underground colony.
The New Moon of Delvia appears in an episode of the first season of Farscape.
