Delvia is the homeworld of the Delvian species. It is located in the Delta Quadrant of the Milky Way, somewhere within or near Peacekeeper Space. The planet is thick with vegetation and plant life -- indeed, even its sentient life is flora rather than fauna. Medicinal herbs and plants are abundant on the planet, and as such medical science is quite advanced.
Delvia was the homeworld of one of the main characters of Farscape.
