Hermione was depressed. She was wandering the dark, desolate halls of Hogwarts late at night, watching the stars and conjecturing what the hell had happened to her life. Nothing was the same ever since Harry had killed Old Voldy Fart, as he was now known to the majority of wizarding children. Even Ron was now gone from her life. It turned out the only reason they 'fell in love' during the search for Horcruxes was because they were desperate for it. They may have been crushing on each other before, but it was lost now. Not even one spark was left.
He was now dating Marietta Edgecombe, and Harry was due to wed Ginny in a week, so she was left alone. Hermione had accepted the role as DADA Teacher at Hogwarts, with Harry occasionally dropping in to lecture those taking their O.W.L's. That was all she saw of him without Ron, and those meeting were awkward enough. He had apologized so many times and she was sick of it. When she almost got her head around it, he would call again and the wound would be freshly opened.
The sky was pitch black, twinkling stars shining happily in a world without pain, grief and loss, providing light until the end of their days. The Whomping Willow was swishing frantically at a bird who was reduced to dust, and all was silent again. Hermione sighed and let her weary feet drag her towards the library - a familiar sight that meant more to her than any other place in Hogwarts, excepting Hagrid's place that is. Madam Pince still treated her like a pupil with return dates, all of which Hermione never failed to keep.
Her slender fingers brushed silently across the spines, the varying textures keeping Hermione on edge until she felt a strange book, which she hefted into her now well-muscled arms. She grunted with the weight of it. Slipping it onto a solid oak wood table, she prised it open.
It was filled with new spells, the likes of which Hermione had never seen, and she gasped in wonder when she came across a particularly interesting spell.
"The tempore vicissim spell, a spell to take the user back in time-" She stopped suddenly. If she went back in time, maybe she might find someone. That would show Ron.
She yanked out her wand and swished it precisely.
"Tempore Vicissim," she chanted and a swirl of grey mist clouded her vision and the world turned black.
