The funny thing about this war is that the gods ought to be embarrassed if asked about why they are taking up arms. So someone cheated at a bidding war for things that they usually use as playthings. It is the sought of the funny reason that mortal kings should fight about not high and mighty gods. Then again, religious wars have never been fought for wise reasons.
Ironic enough, this war isn't an overreaction. It is a justified response albeit not a mature one. It is not like the inciting event of Harkam's and Stelios's war. Last time, Harkam declared war because his demigod was slain. It was his and his demigod's fault. This time he overrode the other gods and acted selfishly. It is his fault again, but he is not the one declaring war this time.
