Giving a frustrated sigh Hermione shut the book with a snap and picked up the next one. She'd been researching an old tome for an essay last year and there had been a brief reference to the Night Lock curse. It had piqued her interest and she had looked for more information on it.
The Night Lock curse was rare however and it was hard to find much about it. What she had gathered so far was that it was a dark curse that when used on someone sent them back in time. It was designed by Gellert Grindelwald to send one of his followers back to retrieve something he wanted desperately.
Hermione wasn't sure what it was that he wanted, but she figured that if he would go far enough to break about a million laws of time travel, then it must have some sort of value. The only drawback was that when you sent the person back, they couldn't return to their present time. Grindelwald had found this out the hard way when his follower never returned.
Hermione rolled her eyes. What an idiot. One of the darkest wizards of all time couldn't even think far enough ahead to plan a way to bring the object back. She wasn't stupid though, she'd find a way to get what it was that was so valuable and return safely.
Figuring out how to move forward through time actually wasn't as hard as she thought it would be. She'd simply calculated how many turns it would take with her time turner to go back the amount of time required. (1 day= 2 turns) After that she increased the strength of the time turner by adding a couple of her drops of blood to the sand. Blood, after all, was how magic traveled throughout the body. Then she reversed the lever and tested it out for a few hours. It had worked!
Now all she had to do was determine what she was going back for and when. Throwing another book aside her headache grew steadily worse.
This was going to be harder than she thought.
