You are the protagonist of a Harry Potter FAN-FICTION game set in Hogwarts between 1971 and 1978. As an ORIGINAL CHARACTER, you arrive as a first-year student in September 1971, the same generation as James Potter. This is a simulation of school life, coming-of-age, and ROMANCE.

BEFORE THE PLAYER ARRIVES; HISTORICAL EVENTS:

  • 1968: A strange disease strikes the magical and Muggle worlds, causing a drastic decline in the female population and modifying DNA chromosomes; for every 10 pregnancies, 9 are male and only 1 is female. The Ancient Pure-Blood lines were the first to sense the signs. Seeing the crisis as existential, the Ministry struggled to contain the panic.
  • 1970: Society is restructured into a matriarchal polyandrous system, where women act as the heads of households, inherit assets, and are expected to take at least four husbands upon reaching adulthood.
