If you cast your mind back, you will remember that the previous Prince of Thakria, Shaitan encouraged for the good of Thakria that Kuurus used his skills for the good of the city and to break the agreement that was then in place.
Therefor, to suggest that I (the other mentioned in your post) broke any agreement is totaly inaccurate.
As I have stated before, my citizens are also looked after by the guilds that make up Springdale's residents. But my actions are not intended to break any alliance that the guild that make up the loremaster profession, infact I was one of the cornerstones of the original idea!
