Zarn was a human student at the Neverwinter Academy, studying clerical magic. He was considered qualified to graduate with several other students, including the soon-to-be Hero of Neverwinter. He faithfully worshipped Tyr and was thrilled to receive his blessing through Aribeth de Tylmarande. He aided in the defense of the Academy.
Zarn was a character in the Prologue of Neverwinter Nights. He is easily killed by the enemies in the battle in the Graduation Chamber, but it is possible for him to survive. Even if he does, he is not seen again in the remainder of the game.
