Briefly. I have a noble in OG and another in Sint that will be forming a new realm for the northern alliance and ruling it. Same guy that used to torture every Fronenite that came through his dungeons when OG was fighting for its very survival against Fronen. Not a huge fan of Fronen, though he likes one or two of the nobles in it.
Edit:
Also, go ahead. Fill your city with militia. Drain your gold intake while your fields burn and its peasants starve. When Fronen slays itself, Beluaterran eyes will fall on whoever aids them.
And remember, one of your allies just said Fronen would be a pack of idiots to wage war. Enweil cannot afford a war right now and Melhed really shouldn't be making themselves a rich, tempting target.
