Agatha Harkness was born many centuries ago (or so she claims) and settled in the English colony of Salem, Massachusetts. There she formed her own coven of witches, hoping to freely practice magic in the New World. Agatha and her group were eventually driven out of Salem following the Salem Witch Trials and they settled in the town of New Salem, a secret magical community in what would eventually be known as Colorado. Agatha Harkness is one of Earth’s most powerful witches and through the years has often served as a tutor to humans and mutants endowed with magic or great power, including Franklin Richards (the son of Reed and Sue Richards) and Scarlet Witch.
