There was once a terrible and great lord who sent his men all across the known world to open political dialog with every kingdom on earth. These men were ambassadors, riding under flags of peace and carrying wealth to trade with each new kingdom they encountered. One of these ambassadors found a great and wealthy kingdom called Khwarezmia. This wealthy land gave its fealty to a certain Sultan Muhammad II who turned out to be very prideful and very unwise Sultan.
One of the cities of the kingdom was named Otrar, and its ruler was a man named Inalchuq. Inalchuq was an uncle of the Sultan and had his favor. When the caravan and the ambassadors arrived in the city, a tentative peace was established with the Kingdom in the East and the land of the Sultan. The ruler of Otrar eventually leveled claims of spying against the caravan and the ambassadors, either to clap them in irons to stop their gathering of information, or simply because of the greed in his heart for the riches the caravan had brought with them. The members of the caravan were executed, and word reach the lord in the East.
Now the lord in the East sent an envoy to the Sultan demanding justice, but the Sultan only beheaded and disgraced the envoys and sent them back with his defiance. And the lord in the East became enraged and brought his army down on the kingdom of Khwarezmia to bring justice to the wrong doers. The kingdom of Khwarezmia had just enraged the Great Chinggis Khan. The Khan ordered the ruler of Otrar captured alive so that he might stand before the Khan and pay for his crimes.
The Great Khan brought his destruction upon the city, and all of the the lands of Khwarezmia; captured Inalchuq and executed him for his greed and his disregard for the sanctity of the peace banner and the position of the ambassador. Inalchuq was put to death by having molten silver poured into his eyes and ears; a Khan's generous attempt to satiate the greed in the wicked rulers heart.
