Undermine is the nefarious capital of the goblin's trade empire, the
Trade Coalition. Located beneath and within Kezan, Undermine is the center of goblin civilization. It is connected to the island via a series of volcanic tunnels which were created by Mount Kajaro's volcanic and tectonic activities.[10][11][12]
The trade princes each control their own private armies and trade fleets. As a result, Undermine is a busy place, as the goblin city goes about its business.
There are some Horde and Alliance ambassadors present in the Undermine.[13]
The main centers of population in Undermine are in volcanic caverns beneath Kezan. Secondary island caverns exist farther away, and the goblins have constructed tunnels of thick glass that lead to these smaller areas. Passing through these tubes means
walking along the ocean's floor and looking out to see the colorful fish and hungry sharks nearby.[12] Bilgewater Port is linked directly to Undermine.[11]
As the capital of goblin culture, Undermine teems with chaotic activity. Goblin alchemists and tinkers practice their crafts and set off explosions. Slave markets bustle in out-of-the-way places. Shops and businesses of all kinds are based here, and the headquarters of the Trade Coalition, the Venture Company and myriad other enterprises are within this city.
In Undermine, you can find the extremes on both ends: reeking slave pens in one area, the trade princes' lavish palaces in another. Zovzik's shop is located in the city.
Of particular interest is the fact that, wandering around Undermine, is a strange breed of a creature called hobgoblins. They resemble goblins, but are much taller and have purple skin.[14]
