Ok so this is an interesting topic. If the Chantry is busy dealing with the Apocalypse and the Magi-Templar War, Alistair or Anora are finally in a position to enforce Circle Autonomy. Now imagine your Warden was a Blood Mage and defiled the Ashes and Andraste's Cult is rapidly gaining converts. With mages fleeing South and Dragons being worshiped Ferelden is suddenly looking like the beginnings of a new Tevinter Imperium. That would be one hell of a world state.
I wonder if they'll keep Andraste's Cult epilogue if the Ashes were laced with Dragon blood. And if it plays off the Magi boon. I'm not expecting much, but it would be interesting to see how this scenario would shape out.
Edit: For the record I'm not anti-Chantry or anything (not a big fan though). This is just an alternate world state I created a while back. Actually finding the Ashes for the Chantry takes the Warden's badassery to level 11.
