Earth Empire factory

Kuvira's factory and re-education facility is one of the most important facilities of the Earth Empire, being the place where Kuvira's superweapon had been designed and built.

History
After Varrick had refused to work for Kuvira and destroyed his destructive invention, Kuvira ordered Bataar Jr. and Zhu Li to recreate the weapon and to bring it to working order as soon as possible. For the workplace for the superweapon, an already existing re-education facility was converted. The troops stationed there and the imprisoned people created an easy to control and cheap work force. After Kuvira's army destroyed the Swamp to get into possession the spirit wines, the construction of the superweapon escalated greatelly.

Only after a few weeks, the superweapon was tested for the first time. The test was a failure, as someone had tackled with the inner mechanism of the machine. The deliberate malfunction almost destroyed the superweapon and vaporized the facility in which it was housed. After a close examination, Bataar Jr. found out, that a gear had almost been broken, causing the malfunction. He then ordered his team of scientists and engineers to thourly search the machine for and other problems. Kuvira arrived and questioned Zhu Li, who said that she had no idea what went wrong. The next day at the testing ceremony the machine malfunctioned again, and this time it had been found out that Zhu Li was the one who had been sabotaging the device. Kuvira sentenced her to be the first person to be killed with the superweapon, which would be fired at an abandoned city.

At the same time, Bolin, Opal, Lin and Toph arrived at the facility to free their family. After using her seismic sense, Toph found out, that their family was held in an underground bunker. The strike force managed to get to the prison chamber unnoticed, and managed to free everyone except Suyin and Bataar, who was afraid to go out of the cage as it dangled several tens of feet from the air. As the guards noticed that something was wrong they sounded the alarm, but the team managed to escape. After escaping the underground prison, the team wanted to leave, except for Bolin, who wanted to save Zhu Li.

Accompanied by Opal, Bolin managed to get to the town on Juicy to save Zhu Li. As they were untying her, the weapon was already firing but missed as it was hit by several large stones, when the others attacked. After a ferocious battle the Beifong family was pinned down and surrounded. They managed to get away when Toph arrived, who until now had been watching Bataar, and destroyed several Mecha tanks with one blow. As Bolin. Zhu Li and Opal returned on Juicy to get them out, Toph commented that Kuvira was giving metalbenders a bad name.
