Given the question: This article: In 1765, the inhabitants of Arkham, Massachusetts, are suspicious of the strange phenomena surrounding the grand "palace" that overlooks the town. They suspect the palace's owner, Joseph Curwen, is a warlock. A young girl wanders up to the palace in a trance-like state. She is led by Curwen and his mistress, Hester, down into the dungeons. The girl is subjected to a strange ritual, in which an unseen creature rises up from a covered pit. The townspeople observe the girl wandering off, and they storm the palace to confront its owner. Though the girl appears unharmed, the townspeople surmise that she has been bewitched to forget what happened to her. They drag Curwen out to a tree where they intend to burn him. The mob leader, Ezra Weeden, insists that they do not harm Hester (to whom he had been previously engaged to marry). Before being burned alive, Curwen puts a curse on Arkham and its inhabitants and their descendants, promising to rise from the grave to take his revenge. In 1875, 110 years later, Curwen's great-great-grandson, Charles Dexter Ward, and his wife Anne arrive in Arkham after inheriting the palace. They find the townsfolk hostile towards them and are disturbed by the horrific deformities that afflict many of Arkham's inhabitants. Charles is surprised by how well he seems to know the palace and struck by his strong resemblance to a portrait of Curwen.

Charles becomes more and more obsessed with the portrait of Curwen, and at times seems to change in his personality. contains an answer for the question: What do Arkham's inhabitants do to the warlock?, what is it ?
