Tonganoxie, Missouri was a predark ville that was destroyed during Skydark, it was located near the settlement populated by the outsiders. It was few hours travel from the redoubt mentioned in Rat King. The area is in a perpetual storm, wind blowing and making life exceptionally difficult for all those who inhabit the area. The outsiders had been at war with the insiders for as long as anyone could remember, and the hatred ran deep. With Ryan's help, they are able to fight their way into the redoubt and kill as many of the 'insiders' as they can before the redoubt starts to collapse around them. One of the few villes not destroyed by Ryan or his people. (Rat King)
There is no Tonganoxie in Missouri, however there is a town by the same name in Kansas, which was platted in 1866. It was named for a local Delaware Indian chief whose name means "shorty" in the Delaware language. Oddly enough Eric Stonestreet's character on the TV show Modern Family claims to be from a Tonganoxie, Missouri.
