Quasqueton is a city in Buchanan County, Iowa, United States.

[2] Just northwest of the town is Cedar Rock, a home designed by Frank Lloyd Wright, which is maintained by the state as a museum.

Quasqueton was the location that several Native American trails intersected.

In 1858 the Quaqueton Mutual Protection Company was organized to prevent against horse thievery.

22.8% of all households were made up of individuals, and 9.5% had someone living alone who was 65 years of age or older.

19.4% of all households were made up of individuals, and 10.1% had someone living alone who was 65 years of age or older.

The place name Quasqueton entered popular culture with the 1979 publication by TSR, Inc. of the Dungeons & Dragons® B1 game module by Mike Carr, entitled “In Search of the Unknown.” The module, designed specifically for new players and Dungeon Masters, featured a fictional stronghold within a rocky promontory that its builders and former residents (a warrior named Rogahn and a wizard named Zelligar) had named Quasqueton.

Prior to creating that work, Carr had lived in nearby Cedar Rapids and, knowing of the town, chose the very distinctive name of Quasqueton for his fictional setting.

Before the internet, few individuals outside of eastern Iowa had heard of it – but after the advent of online search engines, the actual source of the name was revealed to the curious.

In 2018, Goodman Games published "Into the Borderlands," a hardbound volume that reprinted the first two B series modules released by TSR -- B1 "In Search of the Unknown" and B2 "Keep on the Borderlands" by Gary Gygax -- presenting them as originally released for Basic Dungeons & Dragons and in updated versions for the 5th Edition of the D&D game.
