I have to say that, given the state of the Darine Confederacy at this point in the story, including a brewing war between pro- and anti-arcane, Kettenek enforcing neutrality among the Justicars, and a number of surreptious groups jockeying for position:
What makes the Mages Academy so sure they're going to even get takers for the Chancellor's job? If I'm the Miyen Kai, for example, it's MUCH safer out on the hinterlands, staring down the potential threat, than it is to face all of the real ones, declared and undeclared. Likewise the other potential chancellors, all of whom would have left a safer, if not better situation than the one that waits for them in Dar Pykos. It'd be like running the American Self-Defense School in Mogadishu.
You know? "Thanks, but no thanks; I'll just open the Fire Magician's Primary School right over here in Dar Wyoming, where the toughest thing I have to face up to is the odd ECL 4 character and some sagebrush."
