An Unlikely Scholar

Dagna wants to join the Circle of Magi to study their history and lore, but knows that dwarves cannot use magic. She wants The Warden to speak on behalf of her to talk to the Circle.

Walkthrough
Depending upon the choices The Warden makes, Dagna will or will not be able to study at the Circle of Magi.
 * Note: The Warden must complete the Broken Circle quest first.

If The Warden:
 * Sided with the Templars and not the Mages - Knight Commander Greagoir will respond she cannot study at the Tower
 * Sided with the Mages and not the Templars - Enchanter Irving will be open to the idea that she can study at the Tower
 * Convinces Dagna to not join on behalf of her father - Dagna will not study at the Circle

Result
If you talk to Dagna's father after this quest and tell her she left for the Circle Magi, he will be upset that she has become a surface dwarf and casteless. He will refuse to trade with The Warden and forces him to leave his store.
