The Blackwood Society is a secret tradition at Waverly Academy started by Rita Hallowell. The seven members wear black cloaks and go to meeting spots without knowing who any of the others are, and recite the same chant. Hallowell wanted it to be remembered, even if the girls didn't know what it meant, because she knew that someday, someone would use it to find Edgar Allan Poe's final writings. The chant is, "Three is fine but five is more. Even Even nineteen defeats four. Should just seven become lore, at least two will find the door."
