Tyner came from a fairly poor upbringing, and sees things as a matter of efficiency over pleasure. Hence why his manners aren’t that of a normal King.
He’s referred to as Tyner of the West because his family made the trek across the land to live in the east. He works hard, and expects others too as well. Never make him angry, because he has a dedicated army that can, and will, kill for him if he calls for it.
