The Darkhats are a special clan of Mongols, created in order to find the tomb of Genghis Khan, and to prevent anyone else from finding it. They claim to be descended from Khan's most wicked generals and guard his memory and treasures zealously. They are not opposed against using drastic violence to obtain what they want. Their existence was almost of a legendary status, but it was revealed that they still continue to present day and are still looking for the tomb. Mr. Bilharzia was a natural enemy of the Darkhats and kept secrets from them about the location of the artifacts of Dunbelchin.
