Equalist factory

The Equalist factory is an Equalist weapons foundry located beneath Hiroshi Sato's personal workshop in the backyard of the Sato estate.

History
After receiving a tip that Hiroshi Sato was manufacturing Equalist weapons in a factory beneath his home, the Metalbending Police Force conducted a raid on the Sato estate, and subsequently found that the tip was truthful.

Once Tenzin, Korra, Chief Beifong, and some metalbender officers arrived at the factory, they were confronted by Hiroshi Sato, the Lieutenant, and a number of other Equalists. During the confrontation, Hiroshi put his mecha tanks to use for the first time. At this point, Chief Beifong realized that the tip they had received earlier was part of Hiroshi's plan to lure them into his underground factory. After defeating the invading force, Hiroshi ordered that they be taken to Amon. Asami then arrived at the factory and encountered her father, who asked her to join him and the Equalists. Asami took the offer, accepting an electrified glove from her father, but instead used it to shock him and the Lieutenant, thus buying Tenzin, Lin, Korra, Mako, and Bolin, who had found their way to the factory a while earlier, and herself enough time to escape. The remaining members of the police force, however, were captured by the Equalists.

Design
The factory is very large and is accessible via a minecart-like device that carries people deep into the mountainside. The factory has retractable walls made out of platinum - a metal so pure that metalbending has no effect on it. There are two large banners with Amon's face on them hanging from a metal beam in the factory.
