What is war? Well war is a tournament between 2 or more academies. And there is usualy a prize to gain. For example if we were in war and lost they could take all our members, make us delete this academy, and more.
When we have war we will have an academy tourny. And some of the top (10 or other number depending and the number both academies agreed on) will be picked and used as our represinatives in the war. Good thing for us we friend other academies and they some times help us in wars.
