Chapter Five: The Mark of Sigma

'Friendship is unnecessary, like philosophy, like art... It has no survival value; rather it is one of those things that give value to survival.' C.S. "Jack" Lewis, Author of The Chronicles of Narnia

Location: Hogsmeade railway station, Hogsmeade, near Aviemore, Scotland, Earth
Time: September 1991 CE

The scarlet steam engine pulling the Hogwarts Express slowly pulled into the platform at the small station nestled in a forest in Scotland's far north, far away from any known muggle settlements. As the train came to a stop, the train's guard stepped down and immediately started moving along the platform, opening the doors of each carriage, nodding to the solitary member of staff at the almost never used station. The small station building was lit up by several Edwardian oil lampposts along the length of the platform, the lamps casting a warm glow on the train.

The group of new first years stepped down off the train onto the platform, watching as the older students made their way through a stone archway and up a cobblestone path towards a row of carriages.. A booming voice calling the first years over soon led them to a large man, who introduced himself as Hagrid and who soon led them up a well worn stone path away from the station to an armada of small boats on the edge of a large inky black lake.

'Yer'll be gettin' yer firs' look at 'Ogwarts in a mo'' Hagrid called from the boat he had to himself, and sure enough, Harry, Lucy, Hermione and Daphne all let out sighs of awe as over the horizon the beautiful and inviting sight of a fairytale castle came into sight, the lights from the windows glistening across the surface of the lake.

'Abbott, Hannah!' was called out by Professor McGonagall and the first of the new group of friends took her place under the Sorting Hat to find her house at Hogwarts.

'Ah!' Hannah heard in her head and she nearly jumped out of her skin as she realised the Hat was talking to her telepathically. 'Look at you, the first for another year. Let's have a look. Not much difficulty here I'd say. Loyalty, loyalty, loyalty is your creed, and the mark of Sigma is on you, so off you go and welcome to HUFFLEPUFF!' The Hat shouted the last word and Hannah skipped off to join her new housemates.

'Bones, Susan!' was called next and she followed in her friend's footsteps up to the stool, and she too was shocked to hear the Hat's voice.

'Have you met Miss Bones?' Susan looked confused as the Hat was singing in her mind. 'Sorry got carried away there...Let's see, another marked by Sigma, and as loyal and hardworking as you could want. Join your friend in HUFFLEPUFF!'

Several other students were sorted before 'Davis, Tracey!' was called up to the Hat.

'Ah. Yet again I see the mark of Sigma. This is going to be easy this year! Definitely a cunning and ambitious young girl here. Miss Davis, you will do splendidly in SLYTHERIN!' Tracey smiled and headed off to the house of the snakes.

'Granger, Hermione!'

'Welcome Your Grace, it has been many long years since I have met a Ravenclaw heir. Quite obvious really. An unrivaled thirst for knowledge and willingness to learn. The mark of Sigma just makes it official really. Go, and be a credit to RAVENCLAW!'

'Greengrass, Daphne!'

'Miss Greengrass, much like your friend, you are definitely ambitious and are as cunning as a fox. As if the mark of Sigma leaves any doubt, you'll be at your best in SLYTHERIN!'

The house of the snakes once again cheered as the pretty young first year sat down at the table and waited to see where her friends would be sorted.

'Longbottom, Neville!'

'Dear boy, you are more of a credit to your parents than you will ever know. I can see it here in your head, your loyalty knows no bounds and I expect you to be a wonderful wizard in the years to come, and marked by Sigma to boot. Go, have fun, and be your best in HUFFLEPUFF!' As if it were possible, Neville smiled at the Hat's compliments before scurrying off to take a seat next to Hannah at the Hufflepuff table.

'Malfoy, Draco!' Draco heard his name called, and as he had told Harry that he would, he played the pureblood prince role to a tee. He ponced (as he called it) up to the stool and sat down, and as the hat sensed his intentions, it played along, saying only 'Marked by Sigma? SLYTHERIN!'

Draco smirked and he headed to the Slytherin table, sitting down next to Daphne as the next student was called forward.

When Minerva McGonagall called forward 'Pevensie, Lucy!', all the muggleborns, and a great deal of the halfbloods looked at the girl in confusion as she gracefully took her place on the stool.

'Why hello there, a bit out of time you are, I expected to see you nigh on fifty years ago...Even before Sigma's mark you are an easy one. Lucy...the Valiant...Lioness of Narnia, your affinity to Aslan and your true courage in battle. There is only one place you could ever go. Roar Loud, Roar Strong, think of Aslan, and of Narnia, then find your place in GRYFFINDOR!' Lucy smiled at the words of the ancient Hat before she skipped away to the Gryffindor table to await her best friend.

The furtive glances that came when Lucy's name was called instantly became outright curiosity and mumbling when the next name McGonagall read off her scroll was 'Potter-Windsor, Harry!'

'Your Highness!' The Hat's mental voice beamed as it was placed on Harry's head. 'Welcome to Hogwarts! It is an honour to meet the descendant of my creator. Well, let's get on with it...well the last girl was the lioness...but you, it seems are the lion. The beau of Aslan's Dear One (don't deny it boy), but with great and vast intelligence, loyalty to your friends and family, and an ambition to be the best you can. Sigma's mark is joined by Aslan's on you dear boy, Sir Harry the Lionheart, you too must Roar Loud, Roar Strong, think of Aslan, now join your Dear One in GRYFFINDOR!'

Harry took his seat beside Lucy at the Gryffindor table and waited for the last students to be sorted. Finally, 'Zabini, Blaise!' became a 'SLYTHERIN!' and the sorting was finished.

Dumbledore stood from his place at the head table and waved his arms around expansively. 'Welcome(!) to another year at Hogwarts. New students, and some old students, should take note that the Forbidden Forest is out of bounds, and that there is a list of some fourteen hundred banned items on the door of the caretaker's office. Now, lastly before the feast, we have some new professors to introduce. Firstly, taking over Defense Against the the Dark Arts, which the new teacher would prefer we call simply Defense, we have Professor Archibald Griffin. Our new History teacher is far better qualified than most, Doctor John Smith, and lastly, our new Muggle Studies teacher is Professor Amy Pond, and her husband and assistant Mister Rory Williams. Students, you would do well to remember that as of this year, Muggle Studies is compulsory for all students. That's all for now. Tuck in!' Dumbledore finished as the plates along all four House Tables instantly filled with food.

Harry and Lucy tagged on to the back of the long line of Gryffindor first years, Lucy taking silent comfort from holding Harry's hand, interlacing their fingers, the memory of her death in 1943 just that morning (from her perspective) and the memory of Aslan's Country fresh within her mind. Her head dropped to Harry's shoulder as they followed the other new lions through a seemingly never-ending maze of corridors through Hogwarts Castle towards Gryffindor Tower, the third tallest of the towers at the Castle. The pompous red headed prefect Percy Weasley who was leading them finally introduced them to the Fat Lady, the portrait whose sole occupation was to guard the entrance to the Gryffindor common room, and informed them that for the first few weeks of term that the password with which entry would be granted would be 'Caput draconis'.

The portrait acquiesced at the "magic words", so to speak, and swung aside, revealing a fairly small round hole in the stone wall through which Percy led the first years through and into the common room.

The common room, Harry and Lucy could now see as they were the last two through the portrait hole, was a circular room with several alcoves off it, most containing desks for study but one contained a fairly large bay window overlooking the grounds. The walls of the room were bedecked in deep red, maroon and gold wall hangings and there was a large painting of a lion over the fireplace which was surrounded by several squashy deep red armchairs and an equally squashy red loveseat, all of which looked very cosy, and their were several portraits lining the walls, all of which seemed friendly enough.

Percy soon started droning about the rules about curfew and proper common room behaviour, Harry and Lucy listened boredly as prefect Percy droned on about rules and regulations. Percy's brother Ron looked equally bored, and the elder twin brothers of Ron had seemed cool, but Percy was just ridiculous. 'Please spend some time getting to know your housemates, your curfew is at 10pm.' Percy informed the first years before heading out the portrait hole.

Harry and Lucy however, after a very emotional day decided to have an early night, and after Lucy gave Harry one more goodnight hug, Harry retired to his new dorm room, located near the top of the tower. Harry was dismayed to find that the lower years, at least, shared dorm rooms with all of their male house yearmates. He did however take in the dorm room, also bedecked in the house colours and the Victorian four-poster made of mahogany it appeared, a fact confirmed by licking the wood, and dressed with a deep red quilt, his new Gryffindor robes already set on a chair beside his bed.

Author's Note: The Hat singing 'Have you met Miss Bones?' is a reference to the Frank Sinatra song Have You Met Miss Jones?. Please read and review and stay tuned for the next installment.
