The Magisterium of Giorra was made up of six Magistrates, representing the six counties Giorra held power over at the time of Giorra's founding.

Magistrates during the times of turmoil that included the Sunnish Wars of Succession and the return of Kaiantor were the hares Barrington of Redgallows, Visposa of Waterbridge, Felt of Freeland, Swyft of Whitebarrow, and Lorrin of Summerwood, and the mouse Culkin of Fastriver.
