I'm afraid that there are a few issues with your post in "The Cyan Sages," Jozi: Firstly, Mephisto and Aerona are already far outside the city, far enough that no one from the city would be aware that they were there.
Secondly, none of the Acolytes know that the man they know as Verisophiles is actually the Cyan Sage Mephisto; official records written by reputable Acolytes list Mephisto as dead.
I hate to be a nuisance, or to put a damper on anything you've planned, but both of those conditions are established fact.
