Agatha All Along has put Agatha Harkness in the spotlight alongside a coven of unlikely allies as they journey down the Witches' Road. And now, they're being chased by Agatha's comic book arch-enemies, Salem's Seven (called by the slightly different name the Salem Seven in the show).
The villains previously appeared in the second episode, stalking Agatha and her coven through Westview in their animal forms, which pay homage to the villains' comic book nature as shapeshifters. And as in comics, the villains have a history that connects directly to Agatha's roots in her original coven.
