Naiad was a Half-Elf Rogue student of the Neverwinter Academy. She was prepared to graduate at the same time as the soon-to-be Hero of Neverwinter. She was excited to meet Aribeth de Tylmarande and was highly impressed at the stealth with which she was seeking a cure via the Waterdhavian Creatures.
Naiad is a character in Neverwinter Nights who appears in the Prologue. She dies easily in the attack on the Academy but it is possible for her to survive. Either way, she does not reappear for the rest of the game.
