Loban

Loban is the owner and founder of the Earthen Fire Refinery and the uncle of Satoru.

History
During the Hundred Year War, Loban came across an area of land rich in natural resources, but was initially unable to develop it because the land was in Earth Kingdom territory, and he was from the Fire Nation. However, following the War's end, he reached a deal with an Earth Kingdom business partner, Lao Beifong, and constructed the Earthen Fire Refinery on the land to mine out its deposit of resources.

One day in 102 AG, Loban put his nephew, Satoru, in charge of operations while meeting with Lao. During this time, members of Team Avatar and the Air Acolytes entered the factory grounds, and during Satoru's tour of the factory, Aang and Toph destroyed one of its machines to save a worker. An angered Loban left the meeting, chiding Satoru for losing the machine, He also told Lao that Satoru was "too scatterbrained to handle any responsibility", and one of them should have stayed behind to made sure nothing happened. However, he questionably looked at his business partner when he took notice of his daughter, Toph.
