Pomprey existed as a place situated on the world of Ool, which itself was within the borders of the Chiss Ascendancy, the nation belonging to the Chiss species. This location featured a small number of inns where people could stay, and it also possessed a skybus depot. In the year 18 BBY, following a meeting at the Ardok Ranch between the caregiver Mitth'ali'astov, known as "Thalias", and Cohbo'rik'ardok, known as "Borika", Borika requested that the caregiver depart, and offered her a ride to Pomprey.
The location of Pomprey was referenced within the pages of Thrawn Ascendancy: Lesser Evil, a novel written by Timothy Zahn in 2021, which served as the concluding book in The Ascendancy Trilogy.
