Throffdon, situated within the Throffdon system of the Inner Rim and the Interior regions, was a planet. Its location was identified as grid square J-9 on the Standard Galactic Grid. This planet circled at least a single sun, which experienced a supernova event during the Imperial Era. In 34 ABY, Eloc Throno, a historian, incorporated a map showing Throffdon's position in his book, Traveler's Guide to Batuu, a work focused on the Outer Rim world of Batuu.
The reference book Star Wars: Galaxy's Edge: Traveler's Guide to Batuu by Cole Horton, published in 2020, marked the initial mention of Throffdon.
