Karzov

Karzov is the second-in-command of the Nashers, the top lieutenant to the faction's true leader, Arlon Bladeshaper. A crafty but violent man, Karzov has never hesitated to use both subtlety as well as outright force in his plans. Famously, he once organized a very damaging riot to distract the Neverwinter Guard while he and a handful of other Nashers assassinated one of the Guard's high-ranking officers.
It is well-known that Karzov is in charge of the Nasher takeover of Blacklake. His motives for doing this were not understood, however, until he masterminded the theft of the Crown of Neverwinter. With Bladeshaper nowhere to be found, it is unclear whether Karzov is acting as part of a larger Nasher plot, or if this is the first step in some sort of coup.
