The term "face-changing" originated from the Orcs internment camps in Lordaeron.
Every time Jaina came to inspect the Orcs internment camp, Thrall would hide the elite Orcs Warriors and deliberately let a group of old, weak, and disabled people show themselves in order to win Jaina's sympathy.
Jaina, seeing the suffering Orcs women and children, felt Mercy and returned to Dalaran to report to Antonidas. Antonidas used this to pressure Lordaeron, forcing King Terenas to hand over the last grain of food.
Westfall is part of Kingdom of Stormwind and it's understandable that it must pay some taxes.
However, the Kingdom of Stormwind was warlike and its King Varian was ambitious and fond of military conquests. He waged war year after year, levied exorbitant taxes, and constantly increased the burden on the people of the Kingdom of Stormwind.
Since King Varian's return, Westfall has owed Stormwind City enough taxes to buy a hundred Stormwind Cities. To address this problem, drawing on Jaina's example, the Defias Brotherhood devised a solution.
Every time the Stormwind City tax collectors enter Westfall, every household must hide away their valuables and useful items, making sure they are completely destitute, penniless, and have not a single grain of food.
All the people voluntarily changed into old clothes full of patches and made their faces dirty, so that the tax collectors would see an extremely poor Westfall that could not afford to pay taxes, thus the tax collection could only be delayed indefinitely.
In the Westfall, this behavior is called "face-changing."
Upon hearing that Moonbrook wouldn't have to "change its face" anymore, Headmistress Oriana narrowed her eyes, revealing a dangerous, venomous gaze, and asked in a low voice, "So the rumors are true, King Varian has really lost power?"
The messenger nodded, his eyebrows dancing with excitement, and said:
"The news has been confirmed. Medivh and his mother are finished. Now the entire Kingdom of Stormwind knows, except for King Varian. Lords everywhere are celebrating, seeing this as a rebirth for Kingdom of Stormwind. Of course, we cannot let our guard down. I've heard that the Night Elves and the Gelkis Kingdom are both stirring."
Oriana curled her lips into a wicked smile.
Then the smile grew increasingly arrogant, and the mouth grew larger and larger, gradually filling the messenger's entire field of vision.
The messenger was terrified; he imagined a fire-breathing Dragon laughing at him.
"My Kingdom of Stormwind." The headmistress suddenly stood up, her expression stern:
"My territory, my people, none can take her from my hands. The reign of Stormwind City is over. House Wrynn, your rule is over. I, Katrana Prestor, have returned."
Black Dragon Princess let out a burst of wild laughter, then soared into the sky, casting a shadow over the entire Moonbrook. It was a huge dark cloud that covered the Black Dragon's massive body, and it moved swiftly towards Stormwind City.
The messenger stood frozen for a long time, as if petrified. After a long while, he wiped the cold sweat from his brow, turned back to look at the group of teachers and students who had come to watch the commotion, and asked with lingering fear:
"Did you know that your headmistress is Onyxia, the Black Dragon Princess?"
The teachers didn't seem to care, and the students remained calm, showing no surprise whatsoever.
"The principal can eat half a cow in one meal," a female teacher said politely. "She never hides her appetite and is always complaining that she's not full."
The Black Dragon Princess landed in Stormwind City's Trade District, still appearing as Countess Katrana Prestor.
Only a little over a decade has passed since King Varian returned from the Arena, and Stormwind City has already changed beyond recognition.
The Duke Bolvar, the Earl Agramande (alias VanCleef), General Marcus Jonathan, Marshal Windsor —whether friend or foe, all are now history.
Looking at the bustling crowd and their numb faces, Black Dragon Princess felt a surge of sorrow.
The scars of war are etched on the faces of everyone in Stormwind City. Compared to the time when the Black Dragon Princess was in power, Stormwind City is now incredibly desolate, and the once bustling city is long gone.
Everywhere you look, there are people dressed in rags, barefoot, malnourished children, and disheveled women.
The tavern was no longer Bards' praises of the kingdom, but only with hymns denouncing the crimes of war. The apathetic adventurers drank the cheapest wine, too exhausted even to complain.
As the Black Dragon Princess walked through Stormwind City, all she saw was hunger and suffering, faces devoid of hope. Even the guards of the Kingdom of Stormwind could only patrol in tattered armor.
"Varian, look what you've done!" The Black Dragon Princess clenched her fists, demanding, "These are your people, your people! Don't you have even a shred of Mercy?"
Then, the Black Dragon Princess gave a bitter laugh, "I forgot, Varian has already been devoured by Thrall. You are no longer that person. Who can expect a brute returning from the Arena to govern a country well?"
Governing a large country is like cooking a small fish; it has always been one of the most difficult tasks in the world.
Even a highly intelligent being like the Black Dragon Princess, who has lived for thousands of years, is well-versed in classics, possesses vast knowledge, understands all aspects of human affairs, has a thorough grasp of human history, and whose intelligence is as reliable as her deep breaths, would not dare to claim that she is confident in governing a country well.
Of course, the Black Dragonflight has always been arrogant and conceited, and is by no means lacking in pride and self-confidence.
Princess Onyxia clenched her fists, her face beaming with excitement. "People of Kingdom of Stormwind, your suffering is over! I, Onyxia, have returned!"
Just then, the Black Dragon Princess sensed a hint of danger.
It was a blonde woman walking among a group of suffering people, wearing a magnificent purple mage's robe, the gold trim on the hem as dazzling as her beautiful hair. A familiar face fell into the eyes of the Black Dragon Princess.
"Jaina? No, Jaina has already been killed by Kalecgos, the Aspect of the Blue."
Although the Black Dragon Princess lived in seclusion in Moonbrook as its principal, she never stopped communicating with the outside world. Her many followers and servants, including Goblins, Kobolds, Magnataur, and others, kept her informed of the latest news from the mainland.
Kalecgos, the Aspect of the Blue, is a disgrace to the Dragonkin race, a typical weakling who almost always loses battle and has caused the deaths of countless fellow Dragonkin.
The fact that he bit off Jaina's neck became the only thing he could boast about in his life.
He always loved to vividly recount how he won Jaina's heart, and how he turned the tide at a crucial moment, stepping in to save hundreds of thousands of Orcs when Orgrimmar was in crisis.
With the Black Dragon Princess's wisdom, it's easy for her to analyze that Jaina and Kalecgos have a relationship of mutual exploitation.
Jaina was interested in the bodies of the Blue Dragonflight. As magic users and Spellweavers of Azeroth, the Blue Dragonflight possessed the finest materials for spellcasting.
Kalecgos valued Jaina's relationship with Medivh, and in order to establish a connection with Medivh, he advised against betraying a few of his own people in exchange for crafting several sets of Epic gear for Jaina.
After Medivh abandoned Jaina, Kalecgos immediately turned back and bit off Jaina's neck, a perfectly normal action that won Medivh's favor.
"The scent of High Elves?"
Looking at the little girl who looked exactly like Jaina, the Black Dragon Princess was wary; she sensed the girl's powerful magic.
They both sensed each other's presence and gazed at each other from afar through the crowd.
"The Kingdom of Stormwind is mine," the Black Dragon Princess declared, asserting ownership.
The little girl's smile was as radiant as a flower, like the bright spring sunshine.
"That's not necessarily true, little Black Dragon."
