After Barry's death in Crisis on Infinite Earth, most of his foes, as well as Barry's successor (and former sidekick) Wally West moved to Keystone City, which thanks to the reality-altering effects of Crisis on Infinite Earth, was now Central City's twin city (pre-Crisis on Infinite Earth, Keystone City was located on the parallel Earth known as Earth-Two, in approximately the same space as Central City). Subsequently, Central City was treated as a relatively quiet venue that was not frequently depicted in DC comic book stories, but this situation has changed as a result of Barry Allen's recent return as the Flash.
