Avatar: The Last Airbender - Imbalance, Part 1 (Avatar: The Last Airbender #19)

When Team Avatar return to Earthen Fire Industries, the factory owned by Toph's father, they find that the once small town is now booming, yet a strange mood hangs over its residents. When Aang is asked to join a business council meeting, the reason becomes clear: a massive bender versus non-bender conflict is threatening to turn violent.
