[@Zendrelax] The npc's reffered to him as that title, so I wasn't sure exactly how they would respond. With that name or his official name.

If they're using it as a nickname "The Koyati" would make more sense. You wouldn't say someone's name is "American", you'd say it's "The American", or else "Joe Bob".
