Dha represented a month within a nine-month calendar utilized on a Raspar system world. In this period, inhabitants anticipated the presence of blazing solar flares that would scar the planet's terrain. A weather report, at a certain juncture, served as a reminder to the populace about mind eels, creatures that became agitated because of these solar flares. Neevlit came before Dha, and Bababbb came after.
The name Dha appeared in "Region 29: The West Fissure," a single-page weather prediction authored by Bob Carrau for the 1993 book Monsters and Aliens from George Lucas. This book is a compilation of concept designs and images originating from diverse George Lucas ventures. Leland Chee, an employee of Lucasfilm who is in charge of the Holocron continuity database, has stated that the material within this book is considered non-canonical.
