Hurren is known as the City of the Elders because it is the seat of the Council of Five, a gathering of five potent magi who come to meet here once a year (although two of the five maintain their primary residences here, the other three rarely are seen within the city walls, appearing only for their annual meeting.) All five are older than any human has the right or the natural ability to be, as the council was founded over a hundred and fifty years ago.
The city itself has grown slowly over the past few hundred years, never really breaking out beyond the old city walls. It sees modest trade with the nearby city-states and pays lip service to the city-state of Khalis.
