Grandin is part of the Inquisition deployment sent to the Frostback Basin. Formerly a member of the Circle of Magi, Grandin was never an effective Mage as he lacked the great talent for magic. A close friend of Lead Scout Harding, Grandin has been serving closely with several members of the team from the University of Orlais assisting the Inquisition's research.
Grandin's friend Jace was killed by the Jaws of Hakkon. Grandin was deeply grieved over the loss of his friend and later when Grandin's patrol was attacked by Hakkonites, he was fatally wounded. In his dying breaths, a Rage demon offered to aid him and Grandin accepted. Now an abomination, Grandin effortlessly eviscerated the Hakkonite attackers and cut a bloody swathe through the Basin composed of Hakkonite corpses.Lead Scout Harding eventually requests the Inquisitor personally investigate Grandin's disappearance, which leads to the discovery Grandin has left his post and the remains of the Hakkonites. Grandin is eventually tracked down to the Ancient Culvert, where he apologizes for leaving his post without permission and swears revenge on the Jaws of Hakkon. Grandin also reveals that he was willingly possessed by the demon and swears that he will continue to fight in the Inquisition's service. The Inquisitor can allow him to leave to hunt more Hakkonites, or deem the situation too dangerous and slay the Rage Abomination there.
