Serpentine Moves (гет)

Medieval Norman Conquest AU.
Fourteen years after eloping with a Muggle, Merope Riddle, of an English wizarding noble family, discovers that she and her son are the last of the line, so she petitions for her title and fiefdom back. Meanwhile Lord and Lady Granger are minor nobility who want their daughter taught magic, but Lord Malfoy, appointed by William the Conqueror to rule English wizards, won’t allow an unattached Muggle-born to study alongside young purebloods at Hogwarts. Merope and the Grangers make common cause and betroth their children, thwarting him for now. But war is coming, and a long, dark path lies ahead.
