**************************Chapter Three: Arriving********************************

Oh, you know I have seen,

A sky without sun

A man with no nation.

Saints, captive in chains,

A song with no name

For lack of imagination.

Harry Potter's summer was still as horrible as the previous summers. At least he had only a week to go till September first, and he would be leaving to go to the Weasley's house tomorrow. Just another day until this torture was over with. Thank God for that.

Sitting at the table in the Dursley's kitchen with the actual Dursley's outside in Aunt Petunia's garden, speaking in loud voices that Petunia's garden flowers were sure to win the award for Best Kept Tulips at the flower show coming up, Harry was glad for a few moments rest. If is Aunt and Uncle caught him taking a break from work, he'd be locked in his room without dinner. And he was hungry.

Quickly standing up, he finished cleaning the dishes as the Dursley family piled into the room. His Uncle Vernon, a big man with a thick neck, glared at Harry and growled, "Hurry up with the dishes, boy. When you're finished you can go to your room."

"Yes, sir." Harry replied, glad that he was almost done.

Draining the sink, he quickly wiped the counter off and walked up the stairs to his small bedroom. Taking out a quill and a piece of parchment, he began writing a letter to his godfather, Sirius Black.

Dear Sirius,

How are you? Done settling into your new house yet? I hope so, because I really want to move in after this school year and get away from the Dursley's. Your place sounds nice. You're probably at Hogwarts now, working on your classroom and getting ready for the new school year. How does it feel, knowing you're going the new Defense Against the Dark Arts professor? I think it's wonderful. This year shouldn't be too bad with you there. So, Dumbledore mentioned something about a surprise? And he won't tell you what it is? I wonder what that letter was about. Must have been really important for him to have rushed out of the Great Hall in the middle of breakfast. I hope it's a good surprise. Well, I should begin on homework. See you in a week. I can't wait.

All my love,

Harry

Putting his letter into an envelope and giving it to Hedwig, his owl, he told her to give the message to Sirius at Hogwarts. Letting her outside, he then sat at his desk and began on his Potions homework.

Buffy was all packed. Giles had told her that she might want to pack all her weapons and most of her clothes. She had grabbed sweaters and pants because Willow had said that it was going to be pretty cold in England. She had also packed a few dresses, shorts, skirts, and tank tops. She had a bag of make-up, hair stuff, and perfume. Giles said there's not electricity at Hogwarts, so she skipped over the curling iron and hair dryer. She was ready to leave to Hogwarts.

**************

August 31st rolled around, and Buffy got a letter from Professor Dumbledore, telling her that Rubeus Hagrid the groundskeeper and Care of Magical Creatures professor at Hogwarts, was going to arrive at her house at 3:00 p.m. her time, 10:00 p.m. England time, and to be waiting in her backyard. At exactly 3:15, there was a great rumbling overhead, and suddenly a big giant of a man on a flying black motorcycle landed in Buffy's backyard. Pulling a stake from her jacket pocket, Buffy blinked in surprise.

" 'ello there, little ones. How are ye doin'? Rubeus Hagrid, but you can call me Hagrid. Which one of ye is Buffy Summers?" Asked the man.

Buffy raised her hand, speechless. 'This is going to be rather interesting' she thought.

**************

'Wow! Now, this is the way to travel!' Buffy thought to herself, taking in the view. She was on the back of Hagrid's flying motorcycle. And they were in the air. Hagrid had shrunk down all her trunks and suitcases, which was pretty interesting in itself. She had said goodbye to all her friends and her sister. Even Spike, who was lurking in the shadows out of sunlight's way, got a quick hug and a 'bye'.

Buffy had cried a little, so she had hurriedly got on the bike with Hagrid and took off, with her promising to write. They had been in the air for a little over an hour now, and Hagrid said they still had about 45 minutes left. He also said that it will be close to midnight at Hogwarts, and most of the professors would be asleep.

Forty-five minutes later, she was near to being asleep herself. What woke her up was a grinding noise and the sound of the ignition being turned off. Rubbing her eyes, Buffy yawned loudly and looked around. What she saw made her gasp.

They were on the lawn of the most beautiful castle she had ever seen. It was high on a cliff, with a willow tree, a big lake and a forest enclosed in darkness. The forest made her shiver. Shutting it out, she looked at the castle. Most lights were off, seeing as how it was midnight, but the lights that were on glowed warmly and let Buffy see some more of the school. What she saw she decided she liked.

"And this is a school?" Buffy asked in wonderment.

Hagrid chuckled. "Sure is," he answered. "Come on, I'll introduce ye to th' professor. Dumbledore should be waiting up."

And he was. Standing at the top of a long flight of stairs when they walked in was a man with a long snowy white beard and half-moon spectacles. He had a deep blue hat on with matching robes. Printed on the robes were stars and moons. By his side there was a prim looking woman with her hair in a tight, severe bun. She had glasses on and black, neatly un-wrinkled robes.

Buffy felt suddenly insecure about the way she was dressed. When she left Sunnydale, she thought that her black jeans, tennis shoes, and tank top were acceptable. No one said anything about robes. 'Oh, well. Who cares?" She thought.

"Hello, and welcome to Hogwarts." The man, who could only be Dumbledore, said in a kind, excited voice. "I am Professor Albus Dumbledore, and this is Minerva McGonagall, Professor of Transfiguration. I am sorry to say that all other professors are getting some sleep for tomorrow. Now, you must be the Slayer, Buffy Summers."

Buffy nodded, liking the guy already. Dumbledore smiled again. He and McGonagall descended the stairs together. When they were in front of Hagrid and Buffy, he turned to the groundskeeper.

"Thank you for retrieving Miss Summers for me, Hagrid. You are probably tired, so why don't you leave Miss Summers' bags here and go get some sleep. After all, you do have a class tomorrow."

"Sure Professor. Good nigh' Professor McGonagall. Nice ter meet ye Buffy. Good nigh' everyone."

"Good night Hagrid. And thanks for the ride." Buffy told him as he took out her suitcases and trunks and unshrunk them.

"Sure thing. See ye tomorrow." He turned and left.

"So, Miss Summers, shall I tell you exactly what you job will be here at Hogwarts?" Dumbledore asked Buffy.

"Only if you call me Buffy, Professor Dumbledore." Buffy responded.

"Of course, but only if you call me Albus." He answered, eyes sparkling.

"I'll think about it."

"Okay then. Now, your job here will to be helping Sirius Black teach Defense Against the Dark Arts. You have experience with that, of course." Buffy nodded. "So, you'll be helping with the vampires, Slayers, and demons section. You will also be patrolling the Forbidden Forest," Buffy recalled the dark forest, " and be on the look-out for trouble. If Voldemort attacks, we're going to need your help. If he doesn't, there are sure to be attacks by his followers. The students arrive tomorrow night in time for dinner. I will introduce you to the other professors and the students at the same time as a surprise.

I do love surprises. So, if you will avoid being seen by the professors or anything else until 8:00 tomorrow night, everything will work out. I will enjoy seeing the look on everyone's faces. Tomorrow, when you come out for dinner, just go down that hall," he pointed, " to the big doors. That is the Great Hall. Breakfast and lunch will be served to you in your room by the house-elves," at this Buffy raised her eyebrows, "so, Professor McGonagall, if you would be so kind as to show Buffy her room, I will be grateful," he finished.

"Of course, Headmaster." It was the first time McGonagall spoke.

"Good night, Buffy Summers. I will see you again tomorrow night. And remember to be in the Great Hall by 8:00 p.m. Good night Minerva." With that he turned and walked away.

"Good night, Albus." McGonagall said.

"Night, Dumbledore," Buffy echoed.

"Well, come this way." She started to walk away with two of Buffy's lighted suitcases, leaving a trunk of weapons and a third suitcase. Buffy grabbed them and hurriedly followed McGonagall up a flight of stairs, down a hall, up another flight of stairs, down another hall to a bedroom with a statue of an angel in front of the door.

"You need to make up a password," Professor McGonagall said briskly.

"Umm…chocolate kisses?" Buffy asked tentatively. The statue swung open, revealing a large office on the other side of the door. The office had a desk with a chair, a few couches, and two seats in front of the desk. The wall had a few paintings of moving people. Moving people! Buffy stared in amazement, but the action of McGonagall opening another door made her move.

Behind this door was another large room with a queen sized bed with red silk sheets. It had couch, dresser, table with two chairs, and a walk in closet. Professor McGonagall put her bags down and motioned toward the many candles and lanterns about with her wand, muttering words. The room was lit up.

Pointing to another doorway, McGonagall said, "That is the bathroom. It ahs a bathtub, so you do not have to worry about finding a place to bathe. Breakfast will be brought to you at 10:00 promptly. Have a good sleep." She turned around and started towards the doorway.

"Good night." Buffy said.

"Good night." McGonagall replied.

Sighing, Buffy got out her pajamas, decided to unpack tomorrow, and walked into her new bathroom. It was huge! It had a big tub, more like a hot tub, and a long counter with two sinks and a big mirror. The floor and walls were marble, and there was a shower stall at the far wall. Buffy quickly changed and brushed her teeth and hair, and washed her face.

Walking into her new bedroom, she blew out all the lanterns and candles but one, she slipped under the cool sheets and closed her eyes, bracing herself for the screaming and green flash of light. Nothing. Thank God. Turning over, she sighed, trying not to cry. This was not the time. Yet she couldn't help the few tears that escaped eyelids to fall down her face as she drifted off to sleep.

To be continued….
