Corin

Corin was the Grey Warden who ended the Second Blight when he struck down Zazikel in the Battle of Starkhaven.

Background
During the Battle of Starkhaven, Corin's lover, Neriah, threw herself in front of an emissary's bolt to shield him. She was slain, but Corin thankfully survived, going on to plunge his blade into the Archdemon Zazikel.
