Donovia, a planet often experiencing rain, was home to Donovian rainmen, mechanics responsible for the upkeep of signal towers. As the Separatist Crisis unfolded, certain rainmen departed Donovia and became freighter trampers. These individuals journeyed aboard the AA-9 Freighter-Liner known as the Jendirian Valley, transporting refugees from Coruscant to Naboo during 22 BBY.
The initial reference to Donovia within the new Star Wars canon appeared in Tim Veekhoven's "Starship Fact File" section of the 2015 publication Star Wars: Build the Millennium Falcon 50. The world's origins are in the Star Wars Legends continuity, first appearing in David West Reynolds's 2002 reference work Star Wars: Attack of the Clones: The Visual Dictionary.
