Rustwater Port.
Robbie used magic to disguise himself as Goblin from Tanaris, Steamwheedle Port, and infiltrated the port, which was full of slums.
Goblins are probably the race with the most extreme wealth disparity in Azeroth.
For example, in Rustwater Port, there is a scene of extravagant luxury, with Orcs, Tauren, Zandalari Trolls, and other upper-class people indulging in luxurious pleasures. Here, you can buy all kinds of sensory enjoyment with gold coins.
On the other side are countless Lower City, where the Goblins at the bottom have nothing, and they themselves are the private property of the rich.
Every year, countless Goblins, unable to endure their miserable lives, send themselves to their deaths with an explosive device.
The Goblin nobles spare no effort in exploiting their own kind. They claim to be the most business-savvy race in Azeroth, but they have never understood socioeconomics.
When did humanity realize the evils of excessive exploitation?
It was probably the economic crisis that led to the dumping of milk that made capitalists realize that if workers didn't have money, the goods they produced couldn't be sold, and ultimately everyone would go down together.
However, the Goblin goblins cleverly avoided the economic crisis; they never sold their goods to their suffering kin.
Ten thousand years ago, Goblins were slaves, or more precisely, food, of the Trolls on Kezan, much like humans raised cattle and sheep. There are many stories about how Goblins rose to power and created engineering and Alchemy.
The more plausible explanation is that the Goblins rose to power with the help of the Burning Legion, and their engineering and Alchemy also originated from the Burning Legion.
Azeroth possesses a shield built by the Titans, preventing the Burning Legion's Star Destroyers from entering Azeroth.
Many of the Burning Legion's advanced war equipment, such as the Fel Reaver, require maintenance. Originally, this maintenance was done by specialized equipment installed in the Star Destroyers, but now it has to be done manually by the Legion Engineers, which is extremely inefficient and greatly limits the number of Fel Reaver.
So the Legion Engineers came up with a plan: to train native engineers from Azeroth.
They could not choose a united and ambitious intelligent race; teaching them advanced technology would be tantamount to cultivating a potential enemy for the Legion.
Nor should one choose a race that is too stupid, otherwise they will not be able to understand the Legion's advanced technology.
Thus, the cunning, treacherous, and highly intelligent goblins, who took Goblin in exploiting and oppressing their own kind, came into the Legion's sights.
The Burning Legion rescued them from the oppression of the Kezan Trolls. Even now, there are still many Trolls active on the Kezan Isles, and weak Goblin civilians are often captured and eaten, but the Goblin nobles who are busy making money don't care about such trivial matters.
Goblins had gray and earth-toned skin, similar to cavemen. However, while working for the Legion, they became tainted with magical energy, and their skin gradually turned green.
Goblins take pride in their green skin, considering it the color of nobility, so Goblins of other skin colors were gradually phased out.
Rustwater Port was originally a base of the Burning Legion. Ten thousand years ago, before the Sundering of Aman'Thul and the shattering of the continental plates, the Burning Legion hastily withdrew from Azeroth, leaving behind countless materials.
After the Sundering and the sky split open, Rustwater Port was fortunate enough to survive. The Goblins crawled out of the dust in their base and were met with mountains of war machines. This was originally an opportunity for the Goblin, and they might even have unified Azeroth.
But the Goblins lacked this mindset; they quickly descended into infighting, waging endless wars for Wealth. Eventually, the major families divided up the Legion's base, selling these precious war materials as scrap in exchange for their favorite Almond Biscuit Coins.
The Legion left behind so much war material that it hadn't been sold off even after many years. As a result, many steel structures, such as mechs, had rusted. The red rust was washed away by rain, Corruption the nearby sea.
This is the origin of the name Rustwater Port.
For ten thousand years, the Goblins have maintained close ties with the Burning Legion. Every time the Legion invades, a large number of Goblins sign up to join the Legion's artillery ranks, which is a great opportunity for them to rise to the top.
The production line for the Fel Reaver Azeroth required a large number of people to maintain it, and the Goblins of Rustwater Port became active, eagerly signing up. Even the Goblins living at the lowest rungs of society were ambitious, seizing every opportunity to hone their skills in order to one day join the Burning Legion.
Robbie had no doubt that the Goblin nobles possessed information about the Fel Reaver production line.
At this time, the richest Goblin in Rustwater was the Trade King Marty. The next Trade King Gallywix, was just an unknown nobody. He only rose to prominence after becoming Thrall's steward.
In his biography, Gallywix described his rise to power, claiming to be the second richest man in the Rustwater Cartel —but that was nothing but self-aggrandizement.
As a Goblin, Robbie hired an adventure party to protect him. The party leader was a burly Ogre who walked in front of him like a wall.
Upon entering Rustwater Port, Robbie realized he had made the right decision. Countless Goblin civilians surged in, like a green ocean, each holding a resume and introducing themselves.
Fortunately, the Ogre captain stood in front of him, preventing Robbie from being surrounded by a large Goblin civilians.
They were eager to serve a richly dressed noble Goblin like Robbie, but they were a bit too enthusiastic, and there were also some unscrupulous thieves mixed in.
Robbie witnessed the Ogre grabbing several petty thieves and stuffing them into his mouth, but no one came to investigate. However, Robbie later received several bills.
Of course, Robbie needed to hire a guide. One of the adventurers was a Kezan Troll who was very familiar with the Goblin. He went out for a while and found a clever Goblin guide who was said to be a local expert.
This was a Goblin, skin and bones, with small, gleaming eyes. It introduced itself as follows:
"My name is Rick. I know every street and every house in Rustwater Port. I recognize all the nobles and their beautiful daughters. If you're looking for some reasonably priced clubs, I'd be happy to introduce you."
Robbie feigned profundity, adopting the shrewd demeanor typical of a Goblin merchant:
"I'm not interested in any of that. I came to Rustwater Port to expand trade. There are plenty of talented goblins Goblin, and I'm only looking for the most useful ones. Rick, you must prove yourself to me. I'll pay you one hundred, no, ninety Almond Biscuit Coins. I need to see Trade King Marty, by any means necessary."
Rick was silent for a moment, then put on a troubled expression. "That's difficult to do, and it will require more Almond Biscuit Coins."
"Ninety-one Almond Biscuit Coins, no more than that." Robbie's attitude was extremely firm.
Seeing that there was no room for negotiation, Rick pretended to be reluctant and agreed, "Okay, okay, but I need fifty Almond Biscuit Coins as a deposit."
Robbie pulled out thirty Almond Biscuit Coins. "I can only give you thirty, not one more. Rick, I'll remember you. If you run away with my Almond Biscuit Coins, I'll use all my possessions to hunt you down."
Rick happily accepted the Almond Biscuit Coin and excitedly slipped into a sewage-filled alley.
