Uandualon is the name of an entity connected to the Pathfinder navigator known as Qilori, who identified himself as "Qilori belonging to Uandualon."
The initial reference to Uandualon occurred in the book Thrawn Ascendancy: Chaos Rising, the first book of the Star Wars: The Ascendancy Trilogy by Timothy Zahn, which was made available on September 1, 2020. The unveiling of this entity occurred via a Twitter post by the publishing company Del Rey, which included the list of characters for the novel, and was shared on August 5 of the same year.
