Harmonthep was a planet orbiting the star Delta Pavonis. Harmonthep was a swampy world with a nitrogen-oxygen atmosphere. It was also rich in biological life. Consequently, it was also capable of accommodating human life, and for a while was the home of a population of Wandering Zensunni. Inglsey noted Harmonthep as the sixth stop in the Wanderers' migration. The planet was eventually totally destroyed.
