The Doctor, Amy, Rory and River have ended up as students going to the infamous Hogwarts: school for witchcraft and wizardry. Keeping the secret they are actually adults... they must solve what really lurks in the depths of Hogwarts and it's more alien then they could ever imagine...Can they stop it? Or will it be too late?

Time Travel is tricky business. You need training and practice and years of dedication to the craft before being trusted with such a monumental responsibility. When you have none of those things, however, you can always try calling the Doctor, as he seems pretty good at this stuff. So that's exactly what Hogwarts does, and that's how he finds himself babysitting Hermione Granger.

Sarah-Jane Smith has been abandoned at birth, pushed aside by many, forgotten by her father, has dealt with school rivals and is completely fed up. And when the only person in her life is threatened by the Doctor's actions, Sarah-Jane is forced to leave her beloved Hogwarts and save a man she hates. Not only that, but Sarah-Jane's missing mother is in town. Who knew?

What happens when the Doctor stumbles upon the third floor corridor on the left hand side? What if Professor Dumbledore found himself faced with a swimming pool in a library? Only time will tell!

John Smith and Clara Oswald did not expect their first year at Hogwarts to have so much in stall with them. John discovers things about his past when he comes across a familiar name in the year above. A story of adventure and friendship. Set in the time of The Philosopher's Stone.

Harry, Ron and Hermione arrive at Hogwarts for a new term to find that their beloved divination teacher has fallen ill and taken a leave of absence. To fill her place, Dumbledore has hired a strange young man who likes to dress like a mismatched muggle in a pinstriped suit and trainers, and his lovely blond student teacher, Miss Tyler. What is really going on in the Wizard world?

First, you take a brilliant humanoid alien with two hearts and a time machine. Then add a beautiful, yet dangerous archaeologist. Thirdly, add two wizarding students with incredible intelligence and the perfect cover. Finally, place them all in the same magical castle. Those poor Mary Sues don't stand a chance. Crossover between Sporks and Wives, and Elementary my dear Goyle.

Harry walks alone, until a mysterious blue box stops in his path.

The TARDIS has landed the Doctor and Rose in London, but it's not a London they recognize.

Bad things happen when you trust the wrong people. Strange things have occurred since the Golden Quartet started their fourth year at Hogwarts. Claire's dreams have revealed there's an insider working for Voldemort at Hogwarts. They know these strange incidents are connected to Voldemort's spy. It's up to them to figure out the imposter's identity before Voldemort rises to power.

What if Severus had written an apologetic letter, seeking atonement from someone? He never got the forgiveness or closure from Lily... maybe it's not too late now.

A possible short story crossover of post-war Potterverse and Twelve. This will be (shockingly) non-dark.

When Reynie Dursly's parents find out she is a witch, they send her to her to live with her dad's freak cousin and his family.

The Eleventh Doctor meets Amy's grandmother. Who is not very happy with him! One Shot

Harry is Doctor Who's son. Lily is Doctor Who's wife. Harry grows up with the Doctor, Lily, Sirius, Remus, James, Frank, Alice, Bellatrix, Amy, Donna, River, Rory and reappears to go to Hogwarts on his 11th Birthday with his 11 year-old girl-friend Clara and best friend Neville Longbottom…Doctor 11/Lily, Sirius/Donna, Remus/Amy, Rory/Bellatrix, Frank/Alice, James/River, Harry/Clara

An incomplete one shot. My take on the Harry Potter MPD fics, there is little to no plot and a small twist at the end. No pairings.

Harry's super powerful, so are his friends, he becomes a magical animagus and defeats Voldemort while saving Spymaster Snape and everyone lives happily ever after. Ta da! Oh and Sirius and Remus are alive still too, fifth year AU.
