Let me sum up...
It appears to me that this war is rooted in an inherent conflict of playstyles within the sandbox that is Illyriad.
Some players come into Illy looking to beat up on anyone smaller than them. This is a dominate playstyle in many other MMOs. And in the early days of Illy, this was probably the dominate playstyle here.
A group of players decided about a year ago that such a playstyle, if allowed to dominate Illy, would render the complexity of Illy meaningless. It would also mean that Illy would not be a sandbox, it would just be another Zerg MMO. In short, the 2 fundamentally opposed groups can be called "Sandboxers" and "Zergers."
Lorre and Amroth are just 2 of the many players that are Sandboxers. However, both of them are very vocal on GC and thus draw the attention of the Zergers.
Over time, the Zergers have grown and become more brazen. This war is brought by the Sandboxers against the Zergers to preserve the sandbox nature of Illy.
The Zergers have brought this on themselves by refusing to limit their attacks among players and alliances that have the same playstyle. As StJude told me on GC, that's just not fun to them to fight agreed battles. So they attack players that are not interested in Zerging. Well, when a Zerger imposes a battle on a player trying to do other things in the sandbox, then the Sandboxer is being deprived of his right to enjoy his playstyle.
Folks have been asking about Victory Conditions for this war. Here's what I have gleaned...
H? has no specific Victory Conditions, they will decide as the war progresses when they have made their point. The OP in this thread clearly says that H? does not intend player or alliance destruction ... so that is not the starting point for victory in H?'s eyes.
If I'm on target regarding this being a conflict of Sandboxers vs. Zergers, then it would make sense that the final resolution will be the Zergers realizing that attacking other players for the fun of it is NOT a playstyle that a strong group of players will abide.
