"You know, one good thing about the Blight is how it brings people together."
Alistair was a novice templar when Duncan recruited him into the Grey Wardens--or rescued him, as Alistair would say.
Alistair is fascinated by magic, even as his life is defined by fighting its darker manifestations. He has a fondness for strange runestones and figural studies of arcane creatures.
Isoldes suspicions were unfounded, however. Alistair was not Eamons son, but King Marics. Eamon sheltered the boy to hide his existence from Queen Rowan, Eamons sister.
His mother was a serving girl, who died when Alistair was very young. He was raised by Eamon Guerrin, arl of Redcliffe for a time.
The arls wife, Isolde, suspected the reason her husband took an interest in the welfare of a servants child was that Alistair was Eamons son. She insisted that the boy be sent away to the Chantry.
