You know i have been active in these discussions involving Dragon Age's circle system and treatment of Magi for nearly five years on this and other forums.
In that time i have gone from a moderately pro circle rights supporter to my current extreme templar support spectrum of belief.
The Mage question has plagued forums for years.
To me there is but one solution to prevent chaos and destruction.
Total Segregation, total separation.
The circles as they existed actually allowed non magi and Chantry affiliated personal into their boundaries; This led to the problems.
Foreign nobility, Heads of State, people of actual importance in the world merely reminded the mages of the world outside of their prisons, to that? I say resoundingly no. No more; The Circles will exist as they did under the dominion of the Chantry, but within the bounds of the circle, the laws of the state cease, the Circles should be granted to the Chantry as autonomous papal states.
Those of Mage blood and ability shall be taken into these zones and put within the circle; those possessing magical ability shall be treated as magi are; put to the betterment of Chantry and State; providing services in so far as Enchantment and military assistance for Chantry sponsored militant action. Those of non magi but of mage bearing families; including but not limited to Parents, siblings and cousins of second or greater distance shall be taken into the autonomous zones as well.
They shall provide the labor that shall keep the circles isolated; Craftsmen, Masons, Farmers, Archivists, shall be taken from this raw material of magry and from it shall arise a system that is no longer reliant upon Chantry resources for near the entirety of its funding. From this system shall arise the birthplace of a new order, a new stability, one for the betterment of all.
Those who prove aptitude in more physical or militant matters shall also be taken into consideration for Chantry Templars, Obviously it would be for the best if eventually these zones could provide the entirety of their own Templar forces; But from the occurrence in Rivain that is only going to lead to the local Templars abandoning their duty for their countrymen, so in place of local forces, an international Chantry militant body of Templars shall be formed to made up to police these circles, Based all across Thedas on gifted lands.
Given that the Nobility tithe to the Chantry and they have received lands from Heads of State before; it should be no matter to request the additional territory to construct the bases, supply routes and training grounds that shall a force shall require, and through this formation of force and segregation shall Thedas know peace.
The Mages shall be treated as their station requires; And the Chantry will provide the forces that ward over the dangers that erupt from magic, in combination with a rampant militarization effort of course.
