Chapter Eight: A Castle's Hidden Secrets

'Oh, I would never dream of assuming I know all Hogwarts' secrets, Igor.' Albus Dumbledore, Harry Potter and the Goblet of Fire, Bloomsbury

Location: Founders Tower, Hogwarts School, near Aviemore, Scotland, Earth
Time: February 1991 CE

Professor McGonagall led the group of nine first years along the seventh floor towards an almost forgotten tower in a forgotten part of the school. There were no longer any classes held in this corner of the seventh floor, and most of the corridor was covered in a fine film of dust. 'We will have the elves work on cleaning this part of the school as soon as we can.' McGonagall informed the group as she came to a stop outside a portrait on a flat section of wall bridging two parts of the corner.

The portrait was of two men and two women, the four founders of course, and it was the blonde man, who was obviously Godric Gryffindor (or the Master, or Archibald Griffin) who spoke. 'Password?' he asked looking at Professor McGonagall expectantly. 'Every lion needs a lioness.' was the response, and with a nod, the portrait swung forwards showing a large oak door with a iron handle. The professor gestured for Harry to open the door and he led his friends through into the tower's common room.

'Welcome, children, to the fabled Founder's Tower.' McGonagall said with a wide sweep of her arms encompassing the whole of the room. 'The other Heads of House, myself and Professor Dumbledore have decided that as you have not only homework assignments but also work to do with the Wizenagamot and family headship you should have a place where you can do all this work free from distraction. There are several rules you will be required to observe at all times.

After explaining the rules they would be required to observe to retain use of the tower, McGonagall left the room, telling the students that she would leave them to settle in, the group immediately setting about organising the main room of the tower just as they wanted it while Hermione immediately set upon looking through the Founder's private library which was housed within the tower.

Location: Secret Chamber, Hogwarts School, near Aviemore, Scotland, Earth
Time: February 1991 CE

After some two weeks of exploring the Founders Tower between classes, the friends stumbled on a secret staircase that led down through the wall of the castle, down to the basement level. Harry and Lucy led the group of nine forward as they picked their way through the gloom of an area of the castle that looked like it had seldom been used for hundreds of years. The wall hangings and tapestries were moth-eaten, the portraits all covered in black cloth, the torches on the walls casting just the barest amount of light, the charms on them obviously almost run out. Lighting their wands, they continued forwards, following the corridor to its end, being ever cautious, but more confident with every metre they moved forwards until they came upon an oak door with a rusted lock and doorknob, which when Lucy pushed, moved inwards easily.

The group looked curiously around the new room they found themselves in, feeling the rush of almost pure magic, noticing that the rich tapestries in this room showed no signs of decay, nor did the large rug in the centre of the room. In the centre of the rug, a wooden lectern stood tall, a large tome lay open to the first page upon it.

Reminded strongly of the Book of Incantations she had read from on the Dawn Treader's voyage, Lucy leant forward and read the text written there in clear Old English handwriting;

Welcome heirs! You must be our heirs if you have managed to find your way into the Chamber of Secrets, the true Chamber, not the false one so cleverly designed by Salazar. Long ago, when the school was first constructed, we realised that to allow not only the wards to function, but also to allow the castle to withstand the magic performed within, we would need a magical keystone, a room which could draw excess magic away from the castle structure and use it to power the wards. The resulting underground chamber, this chamber, and the network of tunnels and chambers surrounding it, which spread for many hundreds of miles are the schools last defense, the sum total of the knowledge of the founders and of the greatest student in the school's history; Merlin Ambrosius. This tome before you is the fabled Great Grimoire of Hogwarts, and also within these chambers you will find the hidden secret journals owned by we founders and Merlin himself.

Written this 22nd day of August, in the year of our Lord 1092
by Salazar Slytherin, 1st Duke of Slytherin
Godric Gryffindor, 1st Duke of Gryffindor
Helga Hufflepuff, 1st Duchess of Hufflepuff, and
Rowena Ravenclaw, 1st Duchess of Ravenclaw
and witnessed by Merlin, 1st Duke of Emrys, King's Wizard

The nine students gaped in amazement, the purebloods even more so when they heard Lucy say 'Great Grimoire of Hogwarts', the fabled lost knowledge of the founders, which disappeared in 1098 and was never seen again, soon mythologised and dissolved into history.

Further exploration of the vast underground network of caverns and tunnels led them to an armoury just of to the side of the Grimoire Chamber. This armoury also contained a full size archery range and Lucy immediately stepped forward, stringing a bow and pulling an arrow from a quiver hanging on a hook near the firing line. Stepping up to the line, she took aim and loosed the arrow, her friends watching in awe as the arrow flew straight and true to strike the very centre of the bullseye. She smiled when Harry handed her a dagger, and after a few moments getting a feel for the balance, she threw the dagger and was satisfied to see it also score a bullseye, but slightly off to the side after it clipped the arrow already embedded there. Lucy had always struggled going from Narnia back to England, but if there was to be a place such as this in easy reach, maybe it would be that much easy for her.

Location: Muggle Studies Classroom, Hogwarts School, near Aviemore, Scotland, Earth
Time: February 1991 CE

Professor Amy Pond, the first Muggle teacher in the history of the establishment, stood before her first year Gryffindor and Ravenclaw Muggle Studies class, an almost imperceptible smile on her face as the students filtered in, Harry and Lucy having been there five minutes early, the pair currently sitting, heads together, having a conversation and scheming in a way that only best friends can. Heaven help whoever hurts either of those too. Amy thought to herself as the class started to settle down but the scheming continued until Amy decided to embarrass her "adopted younger brother", as she thought of Harry. 'Harry! Lucy! Flirt on your own time!' Amy barked as the whole class erupted into laughter, except of course for Harry and Lucy, both blushing bright red, looking petulantly at one Amy Pond.

'Okay, okay, settle down now class, leave Harry and Lucy alone.' Amy continued, smirking at Harry and Lucy's rebellious looks. 'Now last week we studied the concept of electricity and this week we will be studying its applications in the muggle world...'

Location: Harry's TARDIS
Time: Unspecified

'Bloody Amy Pond! I'll get her back! ' Harry muttered as he raced around his TARDIS console, intent on just getting away from Hogwarts for a while, Lucy watching on, leaning against the console as Harry rushed past her.

'Come on Harry, its no worse than Edmund or Caspian.' Lucy said, 'and at least they're teasing you about someone you like. You do like me don't you?' Lucy asked, her insecurity about her, in her eyes, more beautiful sister raising its ugly head again.

'Of course I like you Lucy, I already told you that you are beautiful on the Dawn Treader, I would have thought that was a giveaway.' Harry reassured and was rewarded by a radiant smile, a big Lucy-hug and another kiss on the cheek.

Time: December 1993 CE

'Neville?' Lucy asked as the group of friends sat around a table in the library revising for upcoming exams. 'This bit about Devil's Snare? Does it have to sunlight, or would any form of magically conjured light suffice?' The question led several other members of the group to listen on in interest as each of the students had a subject in which they excelled most and Herbology was definitely Neville's strong suit.

'Well, no it doesn't. Pure sunlight works best, followed by conjured sunlight, but any other form of light or heat will also work to varying degrees.' Neville answered.

'Thanks!' Lucy said brightly, making a note in her book.

'That's ok. Now could you tell me what the difference is between a basic elixir and a tincture is? I know they are both medicinal.' Neville asked back, Lucy being one of the strongest potioneers in the group.

'Okay...' Lucy said, trying to put it best into words. 'A basic elixir is an aromatic, generally sweetened medicinal potion while a tincture is a potion made up of a benign medicine preserved in alcohol which results in a bitter taste.'

'Right! Brilliant!' Neville replied. Questions continued to be traded back and forth amongst the group right until it was time for dinner.

Author's Note: Well that's first year pretty much done. Please read and review and stay tuned for the next installment.
