War is a terrible thing that leaves entire nations with death and destruction. The order is very aware of this and the decision to allow war to occur is never easy. The true reason why these events are allowed is because nations need to resolve certain conflicts without out intervention if we are to remain anonymous. There is only so much that we can do to maintain order and peace and there are some issues that need to take a natural course. Unfortunately the nature of men is always to wage war against those who oppose him.
This is actually the main reason why the order exists, because without it the entire planet would already be destroyed. We have managed to keep war at a minimum and the atrocities that have occurred all over the world are nothing compared to what would happen if the order wasn’t here. There would really be no world at this point.
