<P> Great Ones , or Black Robes , are magicians on Kelewan who practice magic of the Greater Path . They form the Assembly of Magicians , which resides in The City of Magicians in the northern Ambolina province . Great Ones are considered outside the law , allowed to act largely as they see fit in the name of serving the Empire and even the Emperor can not overrule a decision made by a Great One . Although the Great Ones usually avoid meddling with the day - to - day running of the Empire , there have been certain instances in which their intervention has affected the evolution of the Empire . </P>
