Nikolai is a minor character in the PlayStation version of Crusaders of Might and Magic. He is a guard that can be found on the Citadel, and asks Drake to complete a small task.

His brother Johnathan is working in the prison, and hasn't paid his gambling debt. Nikolai wants Drake to go to the prison and get the money from him.

When Drake returns with the money, Nikolai gives him a fire gem and tells him to give it to his other brother Petros, who will give him a battle axe as a reward, as well as a new quest.

It's possible to keep the money that Johnathan pays, or the fire gem, but the reward for completing the task is worth more than either option.
