Agrysis is the main city, at least by name, on the planet Silei. It has also been refered to simply as The City. It is from this city that almost all major galactic governments of the Avopei-Larru galaxy have held their power. Agrysis has been the center of politics and culture for a number of years and has only faultered culturally to the city Castenona on Crelina since the rise of the Iorou species to importance.
