An Odd Visitor

Disclaimer: I do not own Harry Potter or anything of the associated universe. However, the various OCs that may appear are of my creation, and thusly are treated as such.

A note about this project: Lately, I have been struggling to begin writing a serious story using a few characters that I've thought up. However, I am having trouble threshing out their full personalities, and I felt that an exercise such as this would do very nicely. A commonly known, not too complicated storyline that is oft used in the fanfiction multiverse? I couldn't pass up the opportunity. This is the result. The 'starring role', Mavi Tuo, is my pride and joy, though I'm not opposed to any criticism. Any tips for improving my writing overall are also welcome. Thank you for reading!


This story starts off with Harry and Dudley in the alleyway where they are attacked by dementors in the fifth book, which is the year in which this story will take place. My OC, Mavi Tuo, will be taking the role of Defense Against the Dark Arts teacher, with the usual… interference… by Umbridge. Fun stuff. The OC will show up just prior to the Order of the Phoenix showing up to rescue Harry from the Dursley household.


The pair of boys strolled down the alleyway, arguing over the trivial topic of who Dudley had beaten up that day. Harry, with his ever-present lack of care that Dudley was much, much stronger than he was, kept needling him about it, teasing him about Dudley's gang's nickname for him, and a couple other small topics. Upon reaching the topic of Harry's increasingly frequent nightmares, the pair of them started outright fighting.

Upon Harry pulling out his wand and very nearly cursing Dudley to the deepest pits of Hell, Dudley shuddered, as though he had been doused in icy water. Harry looked at him, confused, as he'd not yet cast a spell. Then he felt it himself…. Dementors. It was an unmistakable feeling. The lights went out, and with them, Dudley's voice came back on.

"Harry, what did you do?" he whimpered. "I can't see. I'm s-so c-cold." He started running away from where Harry was standing, while Harry's eyes started to clear.

"Dudley, come back! You're running right at them!" yelled Harry. He heard Dudley yell, and he feared for the worst. Then he heard him shriek in fear again, and Harry slowly got up from where he had fallen when he was first blinded. Looking up at the scene before him, he saw that Dudley was trapped within the dementor's cold grasp. Turning around, he saw a second one gliding towards him, and groaned in panic.

Knowing that there was no alternative, regardless of the consequences, he did the one thing he could. "Expecto patronum!" Harry wailed. In relief, the conjured silver stag chased down and scared off the first dementor, and then, at his urging, taking down the second one. He was confused, then, when the stag did not dissipate like he expected, but instead stomped the ground, snorting in annoyance.

Looking around, Harry could not see any other dementors or anything of the sort, and so tried himself to dispel the stag patronus. It looked at him in annoyance, with a sort of look in its eyes that said, Are you really that stupid? It then disappeared with a poof of silver mist. Harry slumped to the ground in relief that it was really and truly over.

"Mundungus Fletcher, that blooming idiot," he heard someone quietly cursing. Looking up in alarm, he saw Mrs. Figg staring at him, wringing her hands. "Well, don't put your wand away, there could be something more out here."


After dragging Dudley home, Mrs. Figg trotted back off to her house, with Harry left to face the music about not using magic, the usual overbearing spoiling of Dudley, and various other unfortunate happenings. Once the owls started pouring in, one from the Ministry of Magic telling him about the hearing, and one from Arthur Weasley telling him to stay in the house, not to mention the odd Howler, Harry was sent up to his room.

He promptly sent off a series of letters by Hedwig, and gave a grunt at the Dursley's declaration of going out for the evening. Left with only his thoughts on what had just transpired, he fell into a light, unfit slumber.

A crash sounded through the house, waking Harry. He started, and then got up, reviewing a defensive spell in his head before picking up his wand and slipping quietly towards his bedroom door. As me moved towards it, he heard another crash, this time accompanied with a curse.

The voice was clearly female, though he couldn't identify the words, nor if he knew the speaker. Pressing closer to the keyhole, he tried to hear something, anything, else. He was rewarded by a third crash. It sounded like the lamp in the front hall, near the stairs. The sound was accompanied by a low groan. "I hurt," moaned the unknown woman's voice. "I hate him, I really do."

Harry backed up from the door, wondering at what was happening. He wasn't sure if he should think it was a robber, an assassin, or something else entirely. Deliberating about whether he should unlock his door with magic and take a look, he froze, panicked. The person downstairs had started climbing the staircase, and he had heard the usual creak from the lower step. Uh-oh, he thought.

When the steps were at their loudest, he heard a rattle on his doorknob. "Nope, locked," muttered the voice. It sounded annoyed, though not as much in pain as it had down below. The footsteps moved onto the next room, and tried the door. "Hey, this one's unlocked."

Harry heard the door open, and then a weak exclamation of, "Yes, a bed. Finally." With the sound of bedsprings from his parent's bedroom, the house fell silent once more.


A little later, he heard another crash from downstairs, and tensed, expecting another strange visitor. He was surprised, then, when he heard the familiar voice of Mad-Eye Moody telling someone to be careful. His door unlocked with a click, and he stepped out cautiously, surveying the hall below with unease. Looking down, he saw a group of eight or nine people. At the front of the group were his professors Lupin and Moody, standing with a violet-haired woman. It was then he realized that his wand was still raised, and he lowered it at Mad-Eye's urging.

"You're going to take somebody's eye out, boy," he growled irritably. "And DON'T put it in your back pocket," he added. "Too many people not concerned with wand safety these days… Remus, check him."

"Harry, what form does your patronus take?" asked Lupin kindly.

"A stag…" replied Harry nervously.

"We're good," announced Lupin. The rest of the group sighed in relief, and Moody just shrugged, and started back off to the kitchen.

Once back in the kitchen, introductions were promptly given. Harry was introduced to Kingsley Shacklebolt, Nymphadora Tonks, and a few others. He was also re -introduced to Alastor Moody, which felt odd to him.

Once Moody started cleaning his eye and Lupin discussed that they would be flying back to a secure location, Harry started to feel a bit better about the entire situation. He had almost forgotten about the strange woman who had appeared earlier when she entered the kitchen, blearily looking at them.

"Who're you?" she asked in a sleepy tone. "I was taking a nap here, and then…" She yawned mid-sentence. "You all showed up and started making noise…." Her voice trailed off again. As she was speaking, Harry took note of her appearance. She was easily the tallest one in the room, and she was exceptionally slender. Her silvery-white hair dropped in a straight sheet down her back, and when she looked up, he noticed that she had red eyes.

"Better question," growled Moody, looking uneasy. "Who're you? We checked before coming in; there was no one but Harry in here."

"I'm… Mavi Tuo," she replied, shaking her head to clear it. She finally seemed fully awake. After stretching and yawning one last time, she seemed to be completely lucid again. "Sorry 'bout that. I need a lot of sleep. Anyways, sorry if I got into the middle of something. I'll head out." She turned around, clearly making to head out the door.

"Wait." Moody glared at her. The woman Mavi Tuo looked annoyed, but she turned back to face him. "Who do you work for?"

She looked confused by the question. "Myself. Who else?"

"Are you a vigilante?"

"I suppose you could say that…." said the woman slowly.

"Is that really your name? Mavi… Tuo, did you say?" asked Remus quietly.

"Yep! I chose it. Why?" asked Mavi Tuo. She looked uneasy at the constant prodding. Glancing around the room, she sighed. "Oh, I get it. Organization of some sort?" She sighed at their expressions. "And I was right. Alrighty, then, I'll just leave before you start doing… organization stuff." She turned around again to leave, but was stopped by Moody again.

"I'm sorry, but you'll need to come back with us. You may have heard something compromising to our group." He glared at her, mistrust clear in his eyes.

Mavi Tuo glared right back at him, still halfway out the door. "No. I won't." Her eyes seemed to freeze the room. Only Moody remained unaffected by her cold scowl.

"Then I'll have to make you. I'm very sorry," said Moody. With that, he cried "Stupefy!" and sent a line of red light towards the woman.

She blanched, and dived out of the way. "That looked dangerous," she muttered. Taking up a defensive position, her hands up in front of her, Harry, who had been watching the entire thing from a corner of the kitchen, noticed her gloves for the first time. They were a stark white, but they carried circles of runes upon them. He wasn't sure why, but they made him uneasy.

He found out when Mad-Eye and Remus sent Stunners towards her, only to have them sputter out a few inches from the now threatening-looking woman. When they hit, her red eyes seemed to glow.

"Are you a vampire?" asked Tonks conversationally, while the red eyes remained fixed on the two men in front of her, still shooting ineffective Stunners towards Mavi Tuo.

"No, I'm not," replied Mavi Tuo in a tone suggesting that that was an insult.

"Oh, okay. You know, red eyes, all of that. In that case, I'm very sorry about this," said Tonks with a small, sad smile.

Mavi Tuo turned towards Tonks, her eyes opening wider as she understood Tonks' meaning.

Tonks whipped out her wand, and shouted "Conteram et cadent!" A line of violently purple light shot from the tip and struck the odd shield that Mavi Tuo had kept before her. A sound like ice breaking resounded throughout the kitchen.

"No!" shouted Mavi Tuo when the next round of Stunners hit her, knocking her unconscious.


Once Tonks had finished helping Harry pack the group headed outside, with Lupin in the rear levitating the mysterious Mavi Tuo in front of him. They mounted their brooms and watched the sky. Lupin had the strange woman sitting on his broom in front of him.

After a long flight with Moody and Tonks arguing over safety versus comfort for the entire trip, Tonks, declared they would be landing shortly. Harry looked down over the city, then leaned into a steep dive. The group landed and dismounted on a patch of untidy grass in the middle of a small square. Tonks unbuckled Harry's trunk, and started dragging it towards one of the houses surrounding them.

Harry looked in a confused manner towards the houses, counting in his head. Ten, eleven… thirteen? He looked to Mad-Eye for an explanation. In response, Moody shoved piece of paper into his hand. "Read this," he growled.

Harry read it quickly. The headquarters of the Order of the Phoenix may be found at number twelve, Grimmauld Place, London. Looking up at the houses in front of him, he started to say, "But there is no number tw…" He was abruptly cut off by Lupin, who just said, "Think about what you just read."

Harry thought about it, and then blinked, looking at the houses. There was number twelve, as though it had always been there. "How..?" he asked, looking from one person to another. However, they had already started into the house. "C'mon, Harry!" beckoned Tonks brightly.


End of chapter one.

Brief note: The spell that Tonks uses is derived from Latin. "Conteram et cadent" translates roughly as "Break and fall", meaning that she was simply taking down Mavi Tuo's shield. It was the Stunners that knocked her unconscious.
