This was the weapon used by the most famous assassin in Kara Tur, he was the greatest thief the world had never seen. He received this powerful weapon after completing a series of succesful missions for the emperor, who decided he was worthy of the blade. It was made by the emperors best weapon smiths, and then tempered in the bloods of red, black, silver and blue dragons. The legend says this weapon would make anyone almost as good as thief as the original owner, but because of the strong enchantments, the katana requires much from its wielder, and it is only usable by a thief. How it has ended in your hands, is anyones guess.
