I think imma go ahead and grab the role of Midgate's new Inquisitor. Other defined roles folk could go for include, but are not limited to:

-The Aressan Heir
-Head of Yulian Troops at Midgate
-Head of rebel group. 
-Members of rebel group. 
-Prisoners at Midgate (Either left over from war, breakers of the code, of common convicts.)
-Midgate Citizenry
-Yulian Soldiers/Mages
-Something that ties into Yulian scheming (If you have any ideas feel free to drop me a PM.)

I'm trying to go for a loose sort of feel rather than imposing a strict plot on things.
