Summary: The Battle of Hogwarts goes wrong, and the Sorting Hat is destroyed, activating an ancient protection put on it by Salazar Slytherin that transports it back in time and removes all compulsions on it that Headmasters had placed over time (like Sorting the Houses evenly, Sorting along family lines, rarely putting Muggle-borns into Slytherin, etc).

The Sorting Hat is unable to speak about future events, but it can give vague advice. It then proceeds to wreak havoc with the status quo. I would like it if it also Sorts all the Houses with extremely uneven numbers, forcing the teachers to hold mixed classes to even things out.

I would like it if the Sorting Hat went to one of three eras: shortly before Tom Riddle comes to school, the Marauder's era, or when Harry Potter arrives.

If the Sorting Hat goes back to Tom Riddle's time, then I want Slytherin!McGonagall, Hufflepuff!Riddle, and Ravenclaw!Abraxas Malfoy, with the Dark Lady/Lord of the time coming out of Ravenclaw.

In the Marauder's time, Gryffindor!Narcissa, Slytherin!Sirius (whether he turns against his family or not after ending up in Slytherin is up to you), Slytherin!Lily, Ravenclaw! or Hufflepuff!Remus, Hufflepuff! Bellatrix (loyal to her ideals and family), etc.

In Harry's time, Hufflepuff! Crabbe and Goyle, Slytherin!Hermione, Slytherin!Harry, a bunch of Slytherin Muggle-borns and traditionally Slytherin families in other Houses, and a whole bunch of others moved around.

I would prefer it if the story was gen or, if romance is present, the romance is very, very slight and not focused on.

Bonuses:
-If you choose the Marauder's time, Lily and James don't end up together
-Marauder's time or earlier, Remus becomes the bitter spy on the Dark
-Dark!Sirius (regardless of what time)
-Harry is a parselmouth because Tom Riddle was Lily's father (Petunia is her cousin); therefore Lily is also a parselmouth
-Second year, Harry's the one who is given Tom Riddle's diary
-Semi-decent Snape, although not super nice

Summary: One late evening, while returning home from a visit to Muggle London via the Undergound, Severus comes across an injured and half asleep Harry Potter. When asked about his choice in lodging, Harry retorts with how he is unable to return home, but needed a place to stay far away from both his tormentors and the Magical World. Unwilling to leave the boy be, Severus reluctantly offers Harry a place to stay the night (and just the night) so long as the boy promises not to flirt with unnecessary danger so easily. On the way, Harry begins to describe his fascination with trains and how he believes his life is like one: unable to leave preordained tracks, without it ending his own destruction. Severus tries to tell him that because he is young and because everyone had sacrificed so much for him, not -everything- is set in stone... unlike for some other people.

Summary: When Harry is inexplicably deaged while working a case undercover, his children are suddenly left without a place to live, as Ginny died a few years ago in a tragic Quidditch accident. After an array of problems with other family options, the kids end up living with their paternal grandfather, Severus Snape, whom they've never met. Severus must learn to live with James, Al, and Lily, as well as explain to them why he and Harry remained estranged, even after learning that they were blood relations. Extra points if Severus ends up taking care of baby Harry too!

Summary: Severus and Harry are the only ones left after the Battle of Hogwarts, everyone else having been driven insane or are dead. In order to prevent this from happening, they decide to travel to the past and adopt Tom Riddle Jr, to give him the childhood he deserves.

Requirements:

-Harry and Severus must pretend to be father/son. Maybe even develop this before they go back into the past.

-Harry and Severus have to make realistic preparations: i.e. think of a suitable surname, store up money, birth certs, proof of Mastery, etc. -the time travel device itself has to be more than just a simple spell, charm, or time turner. Make it interesting!

-Tom has to be young, maybe two or three.

-this fic has to involve WWII. don't necessarily need to have actual battle scenes, but how the Wizarding World deals with the Battle of Britain would be interesting.

-Severus and Harry should take an active part in the world, maybe get jobs?

-Grindelwald should be involved...he IS the "Dark Lord" of this time.

I'd actually REALLY like to see this...I'd write it myself, but I have no time ):

Summary:

Warning: Very manipulative and not exactly nice Snape challenge:

For his own selfish reasons, Severus Snape pretends to be Harry Potter’s father.

Possible story:

Severus Snape, together with one or two similarly thinking Death Esters, persuaded Voldemort that "Mudbloods" aren’t complete wastes of space. He pointed out that ‘Magic is might, and might is magic‘ and that a very tiny percentage of the most powerful Muggleborns who passed some special tests could be allowed to become Death Esters and "breed". Lily Evans/Potter was chosen to be one of those potential Death Esters.

The prophecy didn’t change that. But Severus really loved (or desired?) Lily and wished to ensure her security from both sides, in case she refused Voldemort’s offer. So he went to Dumbledore etc., being his own man more than anything else – but his sympathies lied with Voldemort. Lily refused, died, Harry Potter survived and nothing changed.

Several years later, Dumbledore is getting suspicious of Severus monitors him very closely when in Hogwarts or in the OOTP. Voldemort then decides that maybe Snape is expendable. Severus secretly learns this and immediately starts to make a scheme to save his own life; running is no option (see Karkaroff). So being a genius Potions master, no slouch in magical rituals and James’s very distant relative, he then learns about Harry’s "situation" with his relatives – and finds the perfect solution.

To pretend to be Harry Potter’s father.

Bonus points:

1) Severus saves Harry from the Dursleys when he is borderline crazy. Good position to drug him with some potions or mind manipulate him.

2) One of Harry’s friends (Ron?) finds or logically reveals the truth. He is shut up because of his "intolerance".

Not necessarily a very happy story all round.

Summary:

*It's been a long time since Harry Potter defeated Voldemort.The world in general is at peace and perfect for Harry and friends.

*Remus Lupin is alive.

*Severus Snape supposedly dead. Snape's innocence was never discovered, even by Harry. He has gone down in the annals of history as Dumbledore's murderer and Voldemort's right hand man, second only to Him in evilness and darkness,someone who was feared only less than the Dark Lord himself and who almost crippled the wizarding world - only to be found mysteriously killed in the aftermath of the battle.

*A Severus Snape sighting is reported by someone close to Harry, making it impossible for him to ignore it as a hoax call.

*As MLE works overtime to capture Snape under Harry's lead along with the rest of the order and DA, they find various memories/people/letters/other evidence which question their view of the history of first as well as second war.

*Snape is captured after a long chase and gradually the true sequence of events emerges as the interrogations and trial proceed. Even as the MLE starts to put together a damning case, a few people step up in Snape's defence.Deepest secrets are revealed, buried truths uncovered, hidden evidence brought forward and gradually, the entire truth comes to fore.

*Snape and Lily had been married. Up to the writer whether Harry is his son or not.

*A different way of ending the war after Dumbledore's death./

*Harry stays alive despite being a horcrux and sacrificing himself due to something done by Snape

* Oh, and I would love to listen to someone bring to notice the anti-slytherin tendencies of all the main characters in HP incl Dumbledore
