Whipcrack district is located at the eastern part of the city of Egorian in Cheliax. It is located between Aspex Garden and Sorrowgate districts.[1]

The district of Whipcrack, along with Long Market, houses the slave market as well as those industries and business requiring a lot of cheap labor. Auctioneers are here regularly to sell new stock to the highest bidder. Numerous miserable halfling-proportioned dwellings fill half of the district.[2]

It is also home to the Imperial Stadium, where blood sports and other spectacles take place. The public houses surrounding the complex are extremely profitable due to the popularity of the stadium.[3]
