Harry is not only the son of Remus and Lily from a one-night stand but also a werewolf. When Voldemort comes to attack the prophesied children (Cedar Potter or Neville Longbottom), Snape arrives beforehand and tries to warn Lily and James about the Dark Lord's arrival. Instead, he meets Augusta and Remus, the Potters and Longbottoms having gone out for an evening to themselves. Before they can be killed, a portal opens as a result of a kitsune playing around with magic and seeing an opportunity, Snape forces Lupin, his litter of pups and the prophesied children into the portal. As it closes behind him, Snape turns to face Voldemort moments later and is sentenced to Azkaban but no trace of Remus or the children is found. When Remus comes to, he realizes they are on a completely different world in a different solar system where Remus must learn to accept not only his wolf, but learn how to be a father and guardian while searching for a way to return to his own world.
