In the city of Providence, a young writer named Robert Blake finds himself captivated by a dilapidated church on Federal Hill. This church, viewed from his lodgings on the east side of the city, holds a dark and sinister history. Known as the Church of Starry Wisdom, it is believed to be haunted by an ancient and malevolent force, sending shivers down the spines of the local migrant residents.

Driven by his fascination with the occult, Blake decides to delve deeper into the secrets of this accursed church. As he explores the building, he stumbles upon the remains of Edwin M. Lillibridge, a long-lost reporter who mysteriously disappeared in 1893. But that's not all he uncovers. Sitting atop a column in the church's tower, Blake discovers an ancient stone artifact known as the "Shining Trapezohedron." Intricately crafted with otherworldly designs, this artifact possesses the terrifying ability to summon an unimaginable entity from the depths of time and space.

Unbeknownst to Blake, his interference in the church's forbidden artifacts inadvertently awakens the malevolent being that lurks within. Fearing for his life, he hastily escapes the church. However, this eldritch creature, known as the Haunter of the Dark, is bound by darkness and unable to roam freely during the city's illuminated nights.

As fate would have it, a thunderstorm strikes, weakening the city's electrical power. The ominous sounds emanating from the church terrify the locals, who seek solace in the prayers of their Catholic priests, hoping to ward off the unleashed demon. Desperate to protect himself and the city, Blake also beseeches for the power to remain intact. But fate is a cruel companion, and an untimely electrical outage occurs. With the lights extinguished, the Haunter of the Dark seizes the opportunity and sets its sights on Blake's dwelling.

The next morning, a horrifying discovery is made. Blake is found dead, his lifeless gaze fixed upon the haunted church. The cause of death is attributed to a lightning strike, but those aware of Blake's research suspect a more sinister truth - that the Haunter of the Dark claimed his life. His final words, spoken in sheer terror, speak of the approaching menace, "I see it - coming here - hell-wind - titan-blur - black wings - Yog-Sothoth save me - the three-lobed burning eye..."

In a superstitious attempt to rid the world of this evil, a local doctor takes it upon himself to remove the cursed artifact, the Shining Trapezohedron, from the church. With no regard for its true power, he hurls it into the depths of the Narragansett Bay, hoping to sever any connection between the Haunter and our world. But one can only speculate if this ancient evil has truly been banished or if it awaits its next opportunity to descend upon humanity once more.
