Aiden Baird was an apostate mage and Grey Warden from Ferelden. He was born on a small farm in South Reach where he lived with his mother, father, and younger sister. Aiden's magical abilities surfaced when he was 7. He was taken to the Circle of Magi for training. In the Circle Aiden showed considerable talent in magic but out of place. As he grew he became more and more resentful of life in the Circle, living under the constant scrutiny of the Templars. By the time he was 17 he absolutely felt like he couldn't stand it anymore. He and a fellow mage who felt the same way named Anders escaped the Circle.
Aiden was born to Clayton and Marion Baird 20 years before the Fifth Blight.
