She is the leader of the Reef. That happened to take over the Fallen House of Wolves. She isn't the Kell but a much more powerful leader. That is why she is called the Queen. It is like calling Julius Ceasar, the Mayor of Rome. He was an Emperor of the Roman Empire. This is off the Wiki page. So yea House of Wolves still has a Kell, who fled the Reef after the Queen took over. [b]The House of Wolves currently resides within The Reef, serving as loyalists to the Reef's Queen.[1] Vandal Wolves act as royal guards next to the Queen on her throne.[1] The Wolves' Kell was defeated by the Queen's forces and the Wolves were taken over.[citation needed] Although the House was crippled and manipulated, the Queen's forces began to search for the Prime of the House, Kaliks[/b] Source: http://destiny.wikia.com/wiki/House_of_Wolves
