Aria and Ezra Were Just Introduced Into the "PLL: Original Sin" Universe in a Major Way

The original "Pretty Little Liars" takes place in Rosewood, a small, nondescript, white-collar town in Pennsylvania. Fans of the franchise quickly learn that "Pretty Little Liars: Original Sin" takes place in Millwood, PA, another working-class town. The first "PLL" spinoff, "Ravenswood," is also set in Pennsylvania. The only "PLL" offshoot that moves out of the state is "The Perfectionists," which follows Ali and Mona (Janel Parrish) to a new college town in Beacon Heights, WA.

Overall, a Pennsylvania-small-town vibe seems to be the standard for "Pretty Little Liars."
