Khan-Ur, or the primus imperator, is the title used by the supreme rulers of the charr; underneath the Khan-Ur lies the imperators. The Claw of the Khan-Ur is the weapon of the Khan-Ur and having it is one of the requirements for a charr to become a Khan-Ur, another being performing a great act to show the individual's power.
There has been only one true Khan-Ur, whose name is never mentioned and is only referred to as "the Khan-Ur." The Khan-Ur unified the charr before the arrival of humans on the Tyrian continent, and was assassinated by humans around the time of the Exodus of the Gods. The four children of the Khan-Ur formed the four High Legions.
Although a few charr have attempted to claim the title, none have been able to hold it or unite the charr under a single banner.
- Khan was the title for the Mongol leader, similar to the charr title of Khan-Ur.
- Genghis Khan was a Mongol leader who unified the nomadic tribes of Northeast Asia, and whose bloodline created an empire that covered large parts of Asia, the Middle East, and Europe.
