I'll Give You All My Futures

Chapter 1: The Thin Line Between Genius and Insanity

"He can't believe it, he says people seem even more interested in this than the Crumple-Horned Snorkacks!" -Luna Lovegood

February, 2003

Hermione Granger sighed as she twirled her quill between her fingers. How she had been convinced to come to this gathering, she would never know. The convention of witches and wizards in the room were milling about were some of the most ostracized in the wizarding world. A witch walked past her jangling with overpriced glass crystals, talking to a small hand mirror that she held in her left hand. She was going to kill Ginny and Harry. A scowl was starting to make its way on her face as she narrowly ducked under a wizard trying to control a flying creature on a leash that she couldn't possibly identify. Definitely illegal breeding, she thought as the scowl definitely manifested itself as she followed him with her eyes as he disappeared into the milling crowd, making a mental note.

"Hermione!"

Turning quickly with a smile, Hermione felt supreme relief at seeing Luna walking towards her. Seeing her in her everyday robes was still somewhat of a shock to her. Today Luna was wearing powder-blue floor length robes with rather ostentatiously stitched stars in shining red thread. Hermione truly pitied the one who had originally thought that they wouldn't cause a migraine for anyone looking at them. Luna clasped Hermione's hands with her customary smile that seemed to reflect on what was going on in her head than in front of her face.

"We're so glad that you could come to my father's presentation. It's quite his best one yet you understand. He wouldn't even put it in The Quibbleruntil he presented it. He's so excited on what they'll all say," Luna said excitedly, at least for her, since her voice never rose.

Hermione managed a smile, and started absentmindedly twirling her quill between her fingers again as soon as Luna had released her hands, "You know Luna, I don't even know what he's going to speak about."

"That's the surprise for everyone you know. Here, Daddy reserved a seat for you up front," Luna said, steering her past a rather rotund witch that, after she looked back, realized was actually a wizard.

So much for hiding in the back rows that she could slip out early. Settling her mauve colored robes around her, Hermione sat in the seat that was rather obnoxiously calling out her name.

"It'll stop as soon as you sit down," Luna had explained. "Unless you weren't you. Then it would start screaming."

For some reason, she couldn't shake the awful feeling that something wrong was going to happen here. The war had been over for years now, granted four years, but that was the only type of feeling that she could possibly compare it too. She began to nervously tap her quill against the pad that she now had propped on her knees.

"Psst."

Hermione turned, slightly annoyed to find a tiny wizard behind her, his eyes flitting around the room. He shook his head at her.

"You're frightening the nargles," he said, pointing upwards as his head twitched.

Hermione turned forward abruptly, biting her lip angrily. Blast it all, when I find Harry, I'll throttle him, she thought. Sitting here with a bunch of ninny-minded, ignorant, stupid… Thankfully her inner tirade was cut off by a blast of pea-soup colored and scented smoke that clouded over the audience from the short stage in front of the line of chairs.

Coughing and sputtering, Hermione waved a hand in front of her now tearing eyes to see Luna's father appear on the stage, seemingly unaffected by his own entrance.

"Welcome friends!" Xenophilius Lovegood, called to thunderous applause from his audience.

He waited until they calmed and the smoke cleared completely before he began his speech. He made his way about the stage in a strange prancing, hopping manner, that Hermione thought clearly matched his neon green robes, white hair, and crossed blue eyes.

"We shall now be discussing a topic that I have spent the last several years, nay, decades, attempting to study. The wizarding world has always sought to study the different facets of time, but they have neglected a very important occurrence! I have chosen to go forward in this research to further better the lives of my fellow colleagues in spirit. I have chosen the most elusive occurrences to study within time! Time Rips!"

Murmured awe swept through the crowd as Hermione resisted the urge to roll her eyes skyward. Time Rips were an illusion that some wizarding scholars sought to study for funding from institutions and universities. In the end, the so-called "scholars" turned in their research to university that was entirely rubbish after living all-expense paid years in comfortable housing with ample food. Even thinking this though, Hermione whispered the spell so that her inkless quill, spelled by herself, began to transcribe his speech to her pad.

"For centuries, Time Rips were impossible to detect until I made a very valuable discovery, some fifteen years or so ago. The actualities of Time Rips are this, we should not be able to detect them! And in this, I discovered how. Since we are in this stream of time," Hermione glanced behind him to where a glowing board akin to a Muggle blackboard, now had a stream of solid gold pulsing in a horizontal line behind him, "there is no way for us to notice Rips. But certain people," a black dot appeared on the pulsing line, "causeTime Rips."

Hermione frowned and leaned forward slightly in her chair. She'd never actually heard this theory before.

"Up until now, Time Rips were either quickly dismissed or thought to occur because of events. Hartlis Diertwater once thought that they were caused by rising zodiac constellations paired with unusual activities of unicorns," some heads in the audience nodded sagely at this, "But in truth, Rips are caused by us!

"Monumental decisions made by individualscan cause Rips and this is how I discovered it. Regretfully I must say, and will not tell you the circumstances, but with the aid of this device," he held up a momentous hourglass hung about his neck that looked to be ornate faux jewelry when Hermione had first seen it. "A Time Rip was able to take place before my eyes! And quite a powerful Rip it was!"

Hermione could barely hide a smirk at that.

"Now to actually track these Rips, I went back to Ancient Greece where it gave me my first clue. Documented Ancient Greece of course," he chortled a bit, "When one of the few Oracles at Delphi, one reputed to have the best predictions, suddenly disappeared. A simple disappearance to those who do not know what to look for! Before her so-called disappearance, she gave a prediction to the King of Crete that would later cause him to lose a war, but before she told him her interpretation of her own prediction, she wrote – I shall do everything in my power to make this not come about– but it did, because he went to war and his armies slaughtered mercilessly.

"About the Oracle? I tell you this, gathered friends, she did convince the King! The event of telling him actually caused a rip in time," behind him the gold line split and the black dot jumped to the other golden stream, "which led him to stay and home and conquer the invading force which was to come!

"The Oracle was actually a reputed witch who did not need hallucinogens for her predictions, she rather relied on divination. When she caused that Rip, she left our stream of time for another, for the person causing the Rip cannot exist in two different streams of time."

Hermione's mind was whirling at the possibilities. She had always been intrigued by the Muggle theory of multiple parallel dimensions, his theory wasn't actually that far off. He continued to speak, but now she was lost in her own head, thinking of the research that she could do at home, the books that she could use to find out what to look for… The books she could write… The quill on her pad scribbled on, pausing only long enough to jab her hand to make her turn the page.

Her joyous prospects of research were brought to a screaming halt as her eyes caught her left hand.

"I know it's not much, but Bill already got Granny Weasley's ring and…"

Hermione stopped him with a quiet hand on his arm. "It's perfect Ron. It's better."

The tiny gold engagement band held only a single tiny ruby. It was pretty and sentimentally sweet, but predictable. She hated how disappointed she was because it was just so her and she wasn't sure she liked that. But she waspractical, wasn't she?

She began pushing it around her finger. Ron had never liked it when she lost herself in shelves of books. Accepting his proposal hadn't changed how he felt about it either. Not touching books constantly was leading to a lot of nervous habits, she was noticing, as she firmly stopped playing with her ring. She could do some research. It wouldn't kill him.

Thunderous applause tore open the room as Mr. Lovegood started bowing on the stage. Much to her own surprise, Hermione joined in.
