The grand Stybla assembly hall, alternatively referred to as the initial Ruling Family gathering place, was a sizable building that housed wall hangings originating from the ancestral Stybla Ruling Family estate. A selection of keepsakes from this building were relocated to the Stybla stronghold around the year 39 BBY.
Timothy Zahn alluded to the Stybla assembly hall within the flashback sequences of Thrawn Ascendancy: Lesser Evil, a book that saw publication in 2021.
