@Raijinslayer set and apep on neutral terms!? Yeah right. Both gods of chaos will create rivalry and of course them being sworn enemies and fightingneach other each night is not going to help. I think them being chaos gods would be the thing causing most friction between them tho since their minds are wiped.
@Kaithas it would be interesting to see how apep and bast react to each other. They might be great friends but then they discover who they used to be...
