Porthallow Church was an abandoned church at Talland in Cornwall.
At an unknown point, Porthallow Church was abandoned and left empty for many years. In 2012, Malcolm Fade transported the body of Annabel Blackthorn to Porthallow after his convergence in Los Angeles was flooded. He later brought Arthur Blackthorn to the church to complete the resurrection ritual for Annabel. The church's altar held Annabel's body; powered by the junction it was built on, it gave the spell enough power to complete the ritual with Arthur's blood. Annabel then killed Malcolm, leaving his blood on the floor before the altar.
A few days after, Julian Blackthorn and Emma Carstairs traveled to Porthallow from Polperro after being told by local piskies that Annabel would be there. They instead found a note from her explaining that she had fed the piskies false information as she knew Julian and Emma would not leave her alone. The parabatai were then attacked by the Greater Demon Sabnock, who had been unintentionally summoned during the resurrection ritual.
After vanquishing the demon, Julian decided it would be best to destroy the church, as Malcolm's ritual had ripped a hole between dimensions that would continue to attract demons and endanger nearby mundanes. He went on to explain that the church was no longer sacrosanct, and had become demonically aligned. He and Emma then burned the church down using their parabatai abilities to enhance a Fire rune to the point that it burnt through the church's stone walls.
The church was situated on a cliff over a headland, close to the sea and somewhat near Polperro. The area around the church is overgrown, due to its abandonment, but the church itself is in relatively decent shape. It had a single square tower, windows that were carefully boarded out, and a front door with a sign warding off trespassers nailed onto it. Close to where the church once stood was a small graveyard, barely visible in the overgrown grass.
Inside the church were rows of pews, positioned between the arches of a stone arcade that ran along one side. The altar of the church was built directly on a ley line junction, giving it some magical value, and was said to be dated from the time of King Mark.
