Carmena expands the Hidden Cove and donates a large portion of land to serve as a sanctuary for her Indian friends, who are getting massacred by the English settlers. 

Having converted Cantica's esates to liquid assests and produced suitably suspicious documents transferring all of Sylvia's property to her "dear husband-to-be," Cantica and Sylvia sneak out of Ereborough to Bristol and very quietly leave for America.

Rebekah VanNuys decides to study magic after all, makes her way to New Salem, and changes her name to Nava Sophronia.

Maegistra Sophronia prevails upon the town council to establish free schooling at Hogwarts for all the town's children up through the level of basic Muggle education. Muggle parents are delighted, tensions in the town slowly ease, and foundations are laid for peaceful wizard-Muggle integration. 

The total population of the Hogwarts School reaches sixty students in the fall. Profs. Cyrus, Ashwand, Josephus, and Sophronia volunteer to supervise new Houses for the growing school. Cantica, Christopher, Carmena, and Sylvia Houses are founded.
