Usually an AI faction would be fair game for everyone else. I made special rules for the Kwaz because they were huge, I was uniquely placed to benefit and I thought it unfair. I think there are several factions who could take out Sicily so I'm inclined not to apply the same rules, but let me know if you disagree.
@Rougeman, Cumans are up
@Nightbringer, I already switched Sicily so no need for you to intervene.
