She was said to have gained great influence Varian after the death of Queen , during which he subsequently fell into a deep depression. King Varian eventually beat his depression and started to reassert his control over the Stormwind government.
It was at Lady Prestor's behest that the young Anduin Wrynn be given the crown, so that order could be preserved within the Kingdom of Stormwind when the child's father, King Varian, went missing under suspicious circumstances while en route to a diplomatic summit at Theramore Isle.
King Varian was eventually ransomed back to Stormwind by the naga, a ransom that was paid with a painful new tax. The king that returned however, became befuddled around Lady Katrana and permitted her to prevent Stormwind from reinforcing their allies: the Ironforge dwarves, in the retaking of Thandol Span.
She controlled Highlord Bolvar through the use of the . She manipulated the leaders of the Kingdom of Stormwind and the Defias Brotherhood through politics and in some cases, mind control. She has been keeping them in the dark while her brother — Lord Victor Nefarius — manipulates the Dark Horde in its battle against .
King Varian's disappearance was a closely-kept secret, and his sudden "return" (later proven to be a weaker version of Varian that Lady Prestor could use as a puppet ruler) was treated with skepticism by both Prince Anduin and other leaders of the Alliance such as Magni.
When Lady Prestor was revealed to be the broodmother by Marshal Windsor whom she killed on spot, Onyxia kidnapped Anduin and held him hostage in her lair. King Varian and a band of Alliance heroes traveled to Kalimdor and rescued Anduin from the black dragon and at long last, brought Onyxia to justice.
Lady Prestor is the human form of the black dragon , broodmother of the black dragonflight and daughter of . Her name is a homage to the form her father took when human, Lord though their relation, if any, is unknown. While Nefarian is her brother, there is no evidence that the Victor Nefarius' human identity is supposed to be related to the "Prestor" line.
In the RPG
Lady Katrana Prestor and Lord 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.
