Constance Blackhall

Constance Blackhall was the ancestor of Obadiah Blackhall and sibling of Richard Dunwich, mentioned in the Fallout 3 add-on Point Lookout and

Background
Constance was born to the Blackhalls, a family of great wealth that were heavily involved in the commercialization of Point Lookout in the early 21st century. In 2058, the New Plague resulted in the death of Constance's spouse, leaving Constance a widow and placing them as head of the family estate. Constance cooperated with the Isla Negra Real Estate Company, who had been persistent in obtaining the family's real estate for years.

Constance and their brother, Richard Dunwich, were known for their "obsession with the occult," worshipping an "alien entity" known as Ug-Qualtoth. Utilizing their company, Dunwich Borers LLC, the two purchased and excavated land in order to unearth a great monolith dedicated to the entity. A marble quarry that their company used to test their rock-tunnelling drills hid the site of an ancient temple for the "dark gods," whose adherents practiced human sacrifice. Dunwich Borers LLC's abysmal record of human safety precautions, which often led to employee deaths, is rumored to be an intentional move to "bring eldritch attention and supernatural powers" to corporate leadership by means of modern human sacrifice.

Constance used the wealth from the family estate to obtain archaic texts and artifacts, including The Krivbeknih, a book which has ties to Ug-Qualtoth. Constance formed an obscure sect dedicated to the book and drew from a small circle of devotees, serving as the priest. Constance survived during and after the Great War, with local legends accrediting Constance's extended lifespan to the book prior to being stolen, which coincided with their death. Constance's descendent, Obadiah Blackhall, shares the occultism of their descendent and also worships Ug-Qualtoth.
