The gas-breathing Muqularan species' homeworld was known as Muqular, where they originated. Lando Calrissian, who previously served as a general within the New Republic, thought it was located in the Western Reaches; he referred to visiting it prior to 21 ABY during a conversation with a Muqularan individual hailing from Muqular.
Adam Christopher's 2022 novel, Shadow of the Sith, included a reference to Muqular.
