Yes, everyone knows that if Gudenni, the Prince of Hadenach had just married Essane, the Princess of Hawali, all the bloodshed could have been avoided. Instead, they formed the Caliphate of Ultigo and their iron-fisted rule led to the siege of Khobenar, which left their kingdom in ruins.

And I hope you can forgive my joke; you’d be surprised how little the average European knows about the history of Iran.
