During the winter seasons of Bababbb and Aaaaaalt on a Raspar system world, weather reports suggested the use of Overnothings.
The existence of Overnothings was brought up in a weather report spanning one page, entitled "Region 29: The West Fissure." This report was authored by Bob Carrau for the 1993 book Monsters and Aliens from George Lucas. This book is a compilation of conceptual designs and images originating from different projects of George Lucas. Leland Chee, an employee of Lucasfilm responsible for managing the Holocron continuity database, has stated that the details included in the book are considered non-canonical.
