Danville is a minor city sited vaguely in the North East united States. It was founded in colonial times, to exploit the easily accessible copper beds that littered the surrounding area. It was a classic mining boom town, built by the company, and all building, businesses and land owned by “the company”. The Mines were played out by the late 1800’s, and by the turn of the 20th century, the only inhabitants were a few wilderness squatters, ekking out an existence by living off the land.
This ended in 1948, when Kurt Doofenshmirtz, through his newly incorporated Inator Corporation, bought the land from the liquidators of the mining company. He paid to move several hundred families to the area, building new houses and factories for his employees to live and work in. He also provided schools, a hospital and other services essential to life.
Today, Danville, although still heavily tied to the fortunes of the Inator Corporation, is a significant city in its own right. Although not a tourist destination, it draws thousands of commuters through it airport each year. It still has strong ties to the Doofenshmirtz family, with Roger Doofenshmirtz, the younger of the two grandsons of the founder, currently is the city mayor. The Elder, Dr Heinz Doofenshmirtz, heads up the company as director.

The City is divided into 12 districts. The heroes attend Tenth District High School.
