The thing is, Melhed isn't in a spot where it is allowed to voice its gripes. Gripes will get you killed. Moan and complain all you want about how Thalmarkin has got this that and the other thing, but remember: You couldn't beat them with Agyr flying your banner, you definitely won't without it. Antagonizing a bigger neighbor with a solid hold on the region you occupy is a terrible thing to do. If you want to spite someone who just won a fairly one sided war against you, swallow it, or be prepared to pay up for it. The thing is, you don't have to like Thal's attitude, but Thal certainly has to like yours.
