The Tractionstadtsgesellchaft was a group of Traction cities, all of which had called a cease-fire to municipal darwinism in order to combat the green storm. A notable member of the Traktionstadtgesellchaft is Marnau, which was famously shaped like a giant wedge. Tom and Wren Natsworthy were both invited to Marnau, where they met the charismatic Wolf Kobold, son of Kriegmarshal von Kobold. The traktionstadtgesellchaft eventually disbanded after the defeat of the green storm.
