"Are you joking?!" Harry shouted. He aimed his wand at the dementor and reflexively fired a patronus charm at it while drawing on all of his happiest thoughts. The powerful stag erupted and pawed at the dementor, which disintegrated into purple pieces of light before disappearing entirely.

The violent shaking came to a stop, and Harry brushed himself off as he stood up from the floor of the room. The crate was now empty, and shakily Harry shut it. He sat down on the lid and stared at the back wall again. The dementor had been some sort of protection spell, but the way it had dissolved meant it wasn't a real one, nor was it a boggart. Clearly it was guarding something. Something Harry was sure was behind this wall. "Right then," he spoke to himself,drawing a shaky breath.

Beginning on one side, Harry felt his way along the wall. It appeared to be a continuous piece of granite, but he could feel a slight variation in the texture. Working his way across he came to a small dip very nearly the size of his own hand. He placed his palm against the surface and pushed. A light pulsed over his hand, and a circle appeared in the wall, only about 2 cm in diameter. A crystal slid out of the wall and Harry caught it. It was only 4 or 5 cm in length but heavy. The wall still remained a wall though, and Harry continued to feel his way across it. Finally he conceded that what ever was behind this wall could not be found by touch.

Waving his wand in tight circle, Harry spoke firmly. "Murum Aperio." This time the wall responded. A piece of granite differentiated itself and moved backwards before sliding to the side. Another room existed beyond the opening but it was dark inside. Harry lit the tip of his wand and cautiously approached the entrance. Holding his wand aloft he could see a table roughly in the center of the space. He brought out Bill's device and held it up. It was emanating a soft amber glow, no longer blaring obnoxiously. There was no sign of dark spells, so he moved forward staying alert.

Crossing the threshold caused a torch to ignite in one corner and he could see the room's contents more clearly. It was some sort of work space and maybe part office. In one corner sat an enormous carved desk that was littered in scrolls of parchment. A fireplace filled another wall large enough to stand in as was typical for wizarding architecture. There was a narrow bed in another corner but whatever bedding had been there was crumbling with age. A long series of cabinets lined the wall opposite the fireplace and the shelves where filled with crockery, glass vials, dark tools and many items Harry couldn't identify under the thick layer of dust. The table that he had seen from the entrance was made of a smooth alloy. It was triangular with an indentation on each side and smaller triangular panels filling in at the corners. He cocked his head, looking at it curiously. It looked out of place amongst all the other items in the room. Deciding to come back to it he moved to the desk.

While the bedding had clearly not been charmed to last, these parchments had. They appeared at first glance to be recently penned, the language written on them was not. It seemed to be written in Latin, although Harry had never studied the language. He could see a few words that appeared similar to spells he had learned in school, and wished that Hermione could have been here. But maybe she could look at these...

Carefully unrolling one, Harry ran his wand over it and duplicated it onto a parchment he conjured. Once copied, he shrank the scroll and tucked it into a pocket. He copied several more scrolls then turned to leave. He knew had to get back to the main cavern before the SG team left or he might be stranded.

He hurried to the table in the center of the room. He searched it carefully with his eyes trying to make an accurate and complete memory of it. Trying to judge what it was made of, he ran a hand along one of the edges. The moment his hand touched it, the small triangular panels glowed. He quickly stepped back and they dimmed and went dark. Testing his hypothesis, Harry stepped forward again and this time placed his hands palm down on the flat area in the middle of one side. Again the panels glowed, and this time Harry realized why this looked so strange. Everything else in the room could have belonged at Hogwarts, or the Ministry of Magic. But this table looked like non-magical modern muggle technology. It was reminiscent of a computer but without a monitor. A curved depression faced each side of the triangle, and Harry reached forward and ran his hands along it. Tiny crystals lined the depression, but nothing happened when he touched them. Instead he touched one of the small panels on the corner of the table. It sank down under his fingers and Harry realised it was a button. When nothing happened, he pressed another. Still nothing. He pressed a third one, and this time a bright light appeared above the table. The light shimmered in the space and he had the feeling it was waiting for him to do something. He pressed the first button again and a ribbon appeared inside the light. It was three dimensional but transparent. Harry reached out and ran his hand through it, noting that it did indeed appear to be only light. So this was the monitor.

A slot on one edge caught his eye and gave him pause. Withdrawing the crystal the outer wall had given him from his pocket, he saw that it appeared to be a match for the hole in the table. Something about the whole thing made him uneasy, and he considered just leaving it. But his curiosity pushed him and he slid the crystal into the table. A wash of symbols began floating across the space and Harry stared in awe. They were gibberish to him, but clearly had pattern and meaning of their own.

"I have no idea what any of this means; I'm an Auror," he mumbled to himself. Pulling the crystal back out caused the symbols to disappear, leaving the simple light. He stepped back from the table and even that went dark again. From far away a crash rang out and echoed mutely into the hidden room. "Times' up!" Harry commented to himself.

He hurried from the room, and the torch extinguished itself, just as he expected. He pointed his wand at the open passageway and said, "Claudite" before tossing his invisibility cloak back over himself. The wall slid back into place and Harry ran back to the main cavern.

Once aboard the Prometheus, Harry considered his options. One, he could tell his SG team about the discovery of the hidden cave room. The problem with this option was that he would have to reveal a great deal of magic to do so. Two, he could tell the Ministry about the room. He probably should do this one, but he groaned internally. Something about it struck him as wrong. Three, he could say nothing and keep investigating. At the very least he could contact Ron and Hermione and let them know what he had found. This entire thing was not what he had expected and he could really use their guidance just now.

When he had returned to the main chamber, the sounds of a ferocious fight met him and he watched in horror as a Knight attacked Colonel Mitchell. He tried protective shields, but they did little more than blunt the force of the Knight's onslaught and he agreed with the strange woman that the Knight was going to kill the officer. When Mitchell rallied himself and defeated the Knight, Harry had been relieved and he joined the others within the rings that took them back to the ship in orbit. Harry had walked away from the bickering Dr Jackson and Vala, returning to the observation room he had been waiting in initially.

Now he sat, having stowed his cloak away, and mulled over how he could get in touch with his friends. For that matter Bill would want to know what Harry had found as well, and of course Ginny wouldn't stand for being left out. A small smile rose on his face as he imagined her reaction.

"Evans!" Harry looked up, startled out of his reverie. Colonel Mitchell stood before him, sweaty and dirty but grinning from ear to ear. "Come on Evans, we found something the British are gonna wanna to see!"

Rain fell, slashing against the window panes in front of Hermione's desk. A stack of parchments framed her work area, and she steadily moved through them as the afternoon continued. Nothing quite like a rainy day, a warm office and cheery fire, she thought. A house elf marriage license request was next in her stack which she happily approved. She was reaching for the next item in the stack when a bundle of scrolls popped into the air above her desk and dropped onto it.

Raising her eyebrows, Hermione withdrew her wand and slid back from the desk. She rapidly ran some jinx testing spells on the roll and finding none, relaxed only slightly.

Still holding her wand aloft, she aimed it at the bundle and untied it. The thin piece of twine holding the scrolls together undid itself and they rolled away from each other across the surface of her desk. Pointing at the nearest one, she lifted it into the air and unrolled it slowly. The entire scroll was only a few inches long and she could see the writing was microscopic. She sighed, and murmuring another spell watched it enlarge back to it's normal size. Using her wand to continue holding it in midair she read it without touching it. Or tried to. It was written in Latin and was beyond her abilities to translate directly. Frowning at the parchment scroll, she allowed it to settle onto her desk again when she felt the coin in her pocket warm up. Putting the pieces together, she smiled and withdrew the coin.

"Scrolls found in the Tor. Copied the originals for you."

Feeling much better about the whole thing, Hermione quickly restored the remaining scrolls to their original sizes, and stowed them into her satchel. Sticking her head out the doorway she scanned the thickly carpeted room beyond her office.

"Gretchen, I'm leaving early today," she called out to her intern. The recent Hogwarts graduate hurried over.

"That's great, Ms Granger. I mean, not great that you leaving," she fumbled, eyes wide. "It's great for you. Have a wonderful afternoon!"

"Oh, calm down," Hermione admonished lightly. "I'll be back in the morning. Just be sure to submit these," she handed Gretchen her completed stack, "and reset the charms before you leave." Gretchen nodded emphatically and hugged the stack of parchments to her chest. Giving the girl an encouraging nod, Hermione hurried down the hall and out towards the elevators.

Arthur Weasley was already there awaiting the lifts. He gave Hermione a wide smile. "Off early today?"

Hermione wasn't sure what Mr Weasley knew about Harry's mission, if anything, so she hedged. "Ah, well yes."

"Excellent! How wonderful for you." The lift arrived and they both stepped on. Arthur was practically bouncing on his toes, his barely suppressed excitement filling the space with energy. Hermione gave him a bemused smile. "Something up, Mr Weasley?"

It was just the opening he had needed. "Well, since you asked - it's not really a secret after all, as you work for the Ministry and all, you'd be told anyway. They've found it!"

Hermione raised an eyebrow conspiratorially. "Found what?" she whispered.

Arthur shook his head in wonder. "What's inside, inside the Tor of Glastonbury! Isn't it wonderful?"

"Amazing," Hermione breathed, nodding her head. "And you are...?"

Arthur straightened himself proudly. "I have been asked to accompany the select team of historians from the Ministry chosen to aid in cataloguing the find."

"That is wonderful, Mr Weasley," Hermione said with sincerity.

"We are leaving immediately to join the muggles, where we will sign their non-disjointed argyle and proceed inside." The lift came to an abrupt halt, tossing the pair of them out into the atrium.

"Uh huh," Hermione smiled knowingly. "Well, good luck!"

Arthur waved at her as he jogged off to join a small group assembling near the fountain. Hermione paused behind a pillar and withdrew the coin from her pocket again.

"Thanks. Head up - Mr W is coming."
