The letters were identical. Terry Boot had sent letters to three of his friends and housemates from his year; Lisa Turpin, Kevin Entwhistle and Mandy Brocklehurst. They all had one thing in common, they were muggleborn.
Now that they were into the climax of the war, muggleborns had been banned from Hogwarts, eliminating the question about whether or not they should return to Hogwarts in this volatile situation. The other option wasn't exactly very good, because they were muggleborns, they had to go and register at the muggleborn register commissions office in the ministry. There were rumours going round that muggleborns stole magic from other witches and wizards, which Terry as a muggleborn himself, obviously knew weren't true.
If they did what society was telling them to do, and did what they had to do by law, then they would surely either have their wands taken away, or get put into Azkaban, and to be honest, Terry wasn't sure which was worse. So, Terry decided it was time for a third option. After thinking it over for a bit, he realized that for this third option, he would need a couple of friends. His muggleborn friends were in the same predicament as him, and, he preferred to bring his housemates, as, Ravenclaws really did live up to their reputation. With four Ravenclaws, they were bound to get out of any sticky situation. He thought about it, making sure he was defiantly sure of his plans and what he wanted to do, and then penned the letters:-
Dear Mandy/Kevin/Lisa,
As you know, the Ministry has pretty much gone insane, and if we follow the rules, then, as muggleborns, we haven't got a chance at all. What I'm proposing is that first of all, we stick together, and I think we should run from the wizarding world for while. There's no limit to what four Ravenclaws with magic can do in the muggle world, legal or illegal, it doesn't matter, it will still be means to our survival. I can't write too many details incase this letter is intercepted, but just speak the password and this letter will activate as a portkey, taking you to my house with your things so we can meet and discuss plans. Bring any money you have, and any essential magical items. The password is the one we agreed.
Terry Boot.
He tucked each letter into an envelope and then got up to walk into the nearby village, it had a few magical shops, which were of course concealed by muggles. Upon entering the branch of Eeylops Owl Emporium, he payed for three inconspicuous owls to deliver the letter, then headed home to started turn the wheels of his plan into motion.
