Disclaimer: I own nothing.

A/N - This little idea popped into my head last night, and I decided to stay up to make a good start on it. i should really be revising for my important exams that are this week, but as always, fan fiction will come first!

Anyway, this is basically a lot of letters that our favourite Harry Potter characters wrote home after their first day at Hogwarts, starting with Marauder-era characters - The Past, The Trio's generation - The Present, and the next generation - The Future.

(I didn't do James Potter here, because a) I don't really like him, and b) I couldn't think of anything vaguely interesting he;d have to say. Sorry... haha.

Letters Home - The Past

Dear Mum and Dad,

Hogwarts is really good so far! You would love to see it, it looks so magical! In the Great Hall, there are floating candles that float by magic and the ceiling is bewitched to look like the night sky! And everyone here is like me, and we can all do magic, and I feel as if I fit in with them even though I'm not from a magic family, so you don't need to worry about that.

At the Sorting Ceremony, where you get put into your house, a Hat did it! We had to put on the Hat, and it shouted where we would go, and it put me in a house called Gryffindor, which is supposed to be for brave people. I didn't feel very brave after, because Sev got put in Slytherin, so we won't see each other very much. Still, I've made friends with a really nice girl called Alice, and we share the same room. We live in a tower, would you believe it! You have to give a password to a portrait for it to let you in, and inside there's a big fire and it's so wonderful! I just wish you could see it! I can tell I'm going to have so much fun here, and learn a lot. My lessons tomorrow all look really interesting. I have Potions, where you learn how to make potions, with Professor Slughorn, Herbology, which is about magical plants, and Transfiguration, which is where you can change things into other things, and Sev said that soon we'll learnt to fly broomsticks! Imagine, witches and wizards really do fly on broomsticks! And Alice has a cat, but it's not black, it's a tabby and he's called Ginger, so that's not very witchy at all!

I miss you both a lot, and I can't wait to see you at Christmas! I'll keep writing like you asked me to, as I'm sure there will be loads to write about! This boy, James Potter, said that owls are very fast at delivering post, so this should get to you soon. I don't like James though, he was nasty to Severus on the train, but I suppose I shall have to learn to get on with him as he is in my house.

Lots of love from Lily

P.s. Can you tell Petunia I'm sorry and that I miss her too?

Mother,

I was sorted into Gryffindor, not Slytherin, so I do apologise for breaking tradition. Pin all your hopes on Regulus now, because I am certainly not going to be the son you'll be proud of.

I'm even sharing a dormitory with a Potter, one of those famous blood traitors, and another boy, Remus, is a half-blood! It doesn't matter to me one bit, but I thought you would be interested.

Well, I have a lot of things to be doing, so I can't waste time writing this anymore.

Sirius

To Mum and Dad,

So far, everything's fine here. The full moon isn't for two weeks, so I'll have time to settle in before I have to worry about it. I think I'll be able to keep it a secret. Professor Dumbledore showed me what they've built for me. It's a passage in the grounds to a little wooden shack in Hogsmeade, so I can go down there before I transform and stay there until I change back, so no-one ever needs to find out. Also, they built a tree over the entrance to the passage that will injure anyone readily if they try and get down there, so no-one will find me.

I was Sorted into Gryffindor, like Dad. The hat said that I would have done well in Ravenclaw too, but it could see a great deal of bravery in me. I wouldn't have minded either way really, but I do prefer Gryffindor because the people I'm sharing with seem really nice so far. They're called James, Sirius, Peter and Frank, and I can tell that we're going to be really good friends, especially since they don't know about me. To be honest, I don't think they'd mind very much if they did know, but I'm not going to take that chance.

I had my first lesson here today, and it was so interesting. It was Defence Against The Dark Arts, and it was all about what we're going to be studying and it sounds fascinating. I might have to miss the lesson when we do werewolves though, I don't want anyone guessing, after all!

I hope you are both well.

From your son,

Remus J. Lupin.

Mother,

Slytherin, like you.

Hope father is treating you okay.

Severus.
