Valdeer were beings that resided on the planet Naalol, specifically in its mountain regions. These mountains contained several small towns where valdeer shepherds lived alongside artisans and miners; however, following the Galactic Civil War in 4 ABY and the fighting that occurred on Naalol, at least one of these towns was completely destroyed.
The 2015 novel Star Wars: The Aftermath Trilogy began with the book Aftermath by Chuck Wendig, which included a reference to Valdeer.
