Thanks Anaconda.
earcaraxe: yeah I did not want to make a "cheap" province grabbing on you and take the risk to maybe kill one of your armies, or to weaken you to the point where you could not resist to Bandar Log. I thought: "Let's have 2 provinces less and an Abysia as strong as possible to sustain this pointless looser-looser war against Bandar Log, rather than 2 more provinces and a victorious Bandar Log on my Southern flank". So you see, we could not speak but I was your friend :-)
Seriously, beside pure realistic geopolitics, I had the feeling Ermor had a good understanding with Abysia, and only when you turned AI I sent my armies on your lands.
And to make me lie, you are the only nation I did not fight against, except 1/2 unintentional encounters...
