Nichol is a knight of Nohr. Despite being apathetic to most things in the world, Nichol has an unusually strong will to survive. An unused bit of voiced dialogue reveals he fears death above all else.
Nichol appears as the boss of Sophie's Paralogue. Due to his name being mentioned among the names of characters that can only marry the Avatar, as well as having critical cut-in portraits, Nichol may have been intended to be a fully-fledged playable character in earlier stages of the game.
