It seems as the the lacking of a true border definition system has again left two factions in a war state, since there's no clear definitive line that states where one's territory ends and the other begins. Now, the lack of this system is what really makes the game interesting though, especially taking into account that this happened on a pretty regular basis historically, and was more than likely the basis for many wars in Europe and other regions of the world.
Now, with borders remaining as they are, two factions can either be rational and assume that the absolute middle of the area between their fiefs are the true borders, or they can assume that one another owns more or less of the area. Regardless, the fief layout is also rather awkward, considering that in the native game each village is attached and within proximity of a castle or town, New Tadsamesh (owned by CHAOS) is the fief that corresponds to New Tilbaut Castle (owned by FCC). Based on it's location, you could say that it forms an enclave within FCC borders, and in this case I would say that FCC is in the right.
Saxton was making a trip that is probably made on almost a daily basis by FCC members, considering their castle is a considerable distance from their next fief, making that the shortest path on the map. Now, it could be that CHAOS saw his high number of crates and assumed he was going to rob S&D, but based on their posting this was not the idea. They could have saw him as an easy target to raid, and in this case they have no right to attempt to pussyfoot out of a war. Their current excuse is that Saxton was infringing on their borders, but the screenshot shows him moving pretty much right in the middle of the two faction's borders.
If this is just CHAOS protecting their borders, why haven't they attacked FCC members moving between New Tilbaut and New Knudarr previously?
EDIT:
It'd be like if FCC attacked your guys every time they entered / exited New Tadsamesh, since it's so close to their borders. You probably would consider that an act of war, wouldn't you?
And as for the Blackfist guy, I don't know his exact location, but Rhalzo said he wasn't touching New Knudarr's icon, as if that's where the border is drawn. I can't really comment, but if he was right next to New Knudarr I would assume FCC to be correct again.
But then again, I'm just one of Kesh's many accounts, and the #1 FCC Vassal NA, so I would support them.
P.S. that's enough book writing for today.
P.S.S. awaiting Canary's counter-novel.
