[GUIDE] Broken Circle - Mages or Templars? Wynne, Irving, and the Litany of Adralla

During the Broken Circle quest at the Tower of Magi, the Warden is forced to make some drastic decisions.

- Do you ally with Wynne or fight her?
- Do you accept Cullen's request?
- Do you kill all the mages in case they're possessed?
- How do you save First Enchanter Irving?
- How the heck do you use the Litany of Adralla?

and most importantly...

- Do you leave the Tower in the hands of the Templars who have presided over the mages for centuries,  leaving the mages to a certain death?  Or do you trust the mages to examine and verify their own people, saving their lives but perhaps allowing the guilty or possessed to survive?

I've found roleplay reasons for both.  My elves and mages have saved the tower and it's inhabitants with ease, as this is the easiest roleplaying choice to make. 
Supporting annulment is a little harder.  I played a naive Cousland with little knowledge of magic, who was brought up to trust the Templars.  She backed them up with a heavy heart, regretting that she couldn't do more to save the mages.  The decision weighed on her conscience throughout the game.
Then my dwarf simply distrusted magic altogether, and thought it best to cleanse the tower as quickly and efficiently as possible (including Wynne).  

What choices did you make?
