The H.P. Lovecraft Wiki

This subject contains information from the Expanded Cthulhu Mythos, and not based on H.P. Lovecraft's works directly. The Black Whore is an Avatar of Nyarlathotep created by American author Kevin L. O'Brien.


After merging with Doctor Ambrose Dexter and turning him into a new Avatar for himself, Nyarlathotep impregnated Bierce's wife with his own seed; the resultant child, Abigail Dexter, would therefore be Nyarlathotep's Avatar from birth.

As an adult, Abigail earned her doctorate in nuclear physics and took a post with the United States government. She then masterminded a plot to detonate a nuclear weapon underwater to destroy a Deep One city; this fulfilled the schemes' primary goal of cracking an Elder Sign which held the Great Old One Cthaeghya imprisoned.

Abigail Dexter's current whereabouts are unknown.
