Yes Corax is in my players kingdom as the warden. I played up his hatred of the fey and explored why as part of his backstory, a fey charmed and led on his brother when he was younger which resulted in his death.
Since I have a player who is neutral evil in my game to balance out the council I made corax Lawful Evil. So when the Baron (not the evil npc just so you know) told him to stand down he listened due to some high diplomacy rolls.
He now watches the borders for fey, requesting funds from the council for cold iron. He takes bribes and has his own interests on the side but is loyal to a point to the kingdom and the general.
