Tienjing was the capital city of the Anti-Traction League, Tienjing is mentioned in Infernal Devices and A Darkling Plain to have stood for a thousand years.

It was home to the Jade Pagoda, from which most of the Anti-Traction League was governed. When the Green Storm seized power, they expanded and fortified the building. This, however, did not save it from the fury of ODIN which was activated by the Stalker Fang.
