Kinnon is a mage apprentice of the Ferelden Circle of Magi.
Involvement
Kinnon is one of the few survivors inside the Circle Tower during the events of the Broken Circle. If the Warden decides to help Wynne, he or she can speak with Kinnon about the events in the tower. He will also mention that Wynne had told them about Loghain's treachery. However, if the initial conversation with Wynne goes sour and she attacks the Warden, Kinnon will assist her.
