During war Nations fight each other. Towns without a nation are not included, cannot score points and cannot have their townblocks griefed.
Nations can also pay a daily Neutrality cost to avoid taking part in a war. The cost of neutrality is set in the config.yml using price_nation_neutrality: 100.0. In this example, a nation would pay 100 dollars from its nationbank each 'Towny Day'.
While war is in effect, each competing town has a health points property attached to it. Normal townblocks have an HP of 60 while Home Blocks have 120 points by default. This can be changed in the config. A townblock loses HP by enemy-nation residents standing within the townblock. When a townblock has lost all HP and fallen the town which the attacker belongs to gains one townblock and points to their War Score. A Town can be knocked out of a war when their Home Block falls or if their Mayor is killed. A Nation can be knocked out of a war if its capital city is knocked out of the war, or if the King is killed.
Points in war given for the following:
A enemy killed: 1
A townblock stolen: 1
A town knocked out of the war: 10
A nation knocked out of the war: 100
Towny war ends when there is only one nation who's Home Block has not been conquered or when the admin toggles war off. Although the townblocks are restored at the end of war, the damage from any griefing is permanent.
tl;dr, we can't have the war because there are not enough nations. In order to compete, you must be in a nation. If you want more details about the war, read above. I will start the war at around 2:00 PM TODAY (March 29th) on MY TIME (The time on the header) Make your nations quickly! The war will last until one nation remains.
