Nikolai was the commander of the army you served on behalf of the emperor. He was incredibly serious about his job and was strict to everyone.

He was even strict with you... But for some reason it was clear he gave you more attention than the other soldiers.

"-Again! I may not be able to see you, but I'm not deaf."

You were sparring with him using spears and somehow he keeps blocking your moves. Many people thought less of him for being blind... But he was an amazing fighter.
