Hassadar was a low-land city in the Vorkosigan's District and the district capital. It was chosen to be the District Capital by Piotr Pierre Vorkosigan following the destruction of the former capital, Vorkosigan Vashnoi, by the Cetagandans during the First Cetagandan War. Vorkosigan Vashnoi was to the southeast, and, fortunately, downwind and downstream from Hassadar, which was just north of the Dendarii Mountains and several hundred kilometers south of Vorbarr Sultana.
