Lady Katrana Prestor

Lady Katrana Prestor is apparently a counselor and advisor to Anduin Wrynn, the child king of Stormwind, along with Highlord Bolvar Fordragon, who resides with him at Stormwind Keep.

Lady Katrana Prestor and Lord Bolvar Fordragon serve as the king’s main advisors, and they pretty much call the shots. However, Bolvar is not one to insult the judgment of an “educated” lady like Katrana Prestor. It seems like her advice is pretty much the exact opposite of anything a logical person with half a brain would come up with. As a result of Lady Prestor’s intervention, proper human leadership has become impossible. She doesn’t seem to think the other races are necessary. Katrana won’t even allow the king to send reinforcements to human lands that desperately need it, such as Duskwood and the Redridge Mountains. Every report of enemy activity on those fronts is shot down for lack of “proof”, despite knowledge of dead men and women. It's unknown what she did to get the prince’s ear, but for whatever reason she’s managed to keep both the king and Lord Bolvar following her directions (and some of them are clearly nonsense). She’s just playing games with the Alliance troops when they have good men and women dying out on the front. Her motivations are unknown, she’s certainly either working for something malicious, or she is malicious herself.

Lady Prestor is the human form of the Black Dragon Onyxia, broodmother of the Black Dragonflight and daughter of Deathwing. She controls Highlord Bolvar through the use of the. Her name is an homage to her father's human form, Lord Daval Prestor. She manipulates the Kingdom of Stormwind, keeping them in the dark while her brother Nefarian - Lord Victor Nefarius - manipulates the Dark Horde in its battle against Ragnaros.

She appears as a dragonkin on the minimap when Hunters activate Track Dragonkin. When talked to, she will just glare at you.
