Ingsley gives this as the planet name for the sixth stop in the Zensunni migration. It is supposed to have been a no longer existent satellite of Delta Pavonis.

Harmonthep was a planet orbiting the star Delta Pavonis. The planet was eventually totally destroyed.

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.
