[Rq-rules] Shoehorning Thieves World into another world

[royce at efn.org]

Greetings, All,
   Having recently obtained ye olde "Thieves World" RPG-box, I wish to
place it in a larger fantasy world context.  RQ III has a very nice
fantasy Europe, which I had intended to use.  So, ...
   Would the city of Sanctuary fit well as a replacement for Antioch?  Or
is Antioch too central in location?  Petra is landlocked, so that's
out.  Perhaps somewhere in North Africa?
   My goal is to keep Sanctuary either on or periphery to the
Mediterranean.  A Central Asian locale on the Silk Road would be a bit
far.  Nevertheless, if you've got a real gem of a spot in mind, please
feel free to share it regardless.
   Any and all suggestions are welcome.
   Sincerely,
Asher
