Plains factory (Earth-1529)

The plains factory was an industrial complex located in the plains that led to the shores of the Jang Hui River, in the Land of Fire. The plant was where the Land of Fire manufactured metals for weapons and transportation under Ozai's short rule as Fire Monarch. The cooling system provided by the river's water allowed the rapid production of new metal for armors. As a result, however, the factory dumped a large amount of waste into the river, contaminating the air.
