Estalle, situated on an island bearing its name, was a city located on the world of Procopia. From the moment the Tapani Empire was established, this city served as the center of authority within the Tapani sector. It housed The Palace, which served as the home for the Emperors, and subsequently, the Senate Building and Great Council Chambers were also located there. Throughout the Imperial era, Estalle's urban development expanded to completely encompass the entire island.
