Buza System is Dyan's world. 
She has been a Crecheling, one of the System's children, trained in a broad range of skills and knowledge and prepared to take her place as an Urbane, a full-fledged adult member of the desert community with a Calling given her by the System and its Cogitant Council.
Between receiving her Calling and admission into the System, though, stand the Hanging and the Selection. The System has a lesson it wants to teach Dyan about death.
