Summary: In desperation, with the threat of Dolores Umbridge hanging over his head, Dumbledore reaches out to find a new DADA Professor. What he gets is a survivor, a warrior and a rebel… who can't do magic. But maybe this Dark Slayer is exactly what Hogwarts needs.

A/N: I thought that Faith's Mirror of Erised image was clear, but some people thought that the little girl was a young Faith or a child Faith aborted. It was Faith in a happy relationship with Xander and a daughter. The reference to Faith 'destroying' it was a reference to kicking Xander out and not giving him a chance.

A/N2: Sorry about the dense dialogue in this chapter.


Faith sat leaning back on her chair with her feet up on the teacher's table as she took a sip from the soup that was in her mug. It was lunch time and the other Professor's had given up trying to get her to keep her feet off the table. The large mug was a present from Xander. It was black with a large red heart pierced by a stake on one side and 'Faith Lehane, breaking hearts in all the right ways' on the other.

Lowering the cup back to her lap, she surveyed the Great Hall and all the students eating their lunches. The Sixth Years were all dressed in their PE Uniforms as they had their PE Defence class just before lunch. Her eyes darted to her favourite students around the Hall. Potter and Granger made a good team, him brave her smart, kind of reminding her of X and Red. Bones had the stability and backbone to make a good fighter. The Weasley Twins could think outside the box. Luna Lovegood did not even realise there was a box.

The doors to the Great Hall burst open and a dozen adult Witches and Wizards 'marched' in, being led by a short man in an awful green bowler hat and a pudgy woman in bright pink, which made Faith want to either claw her own eyes out or Slay the offending woman.

"Minister Fudge." Dumbledore said standing from his throne like chair. "To what do we owe this pleasure?"

"Don't play games, Dumbledore." The pink woman said. "You've gone too far this time and the Ministry is not going to sit by and let you undermine our way of life."

"I assume the Pink Horror is talking about me." Faith said, taking another sip of her soup.

"Do you know who you are talking to, Muggle." The pink woman said. "I am…"

"Someone who has absolutely no authority over me." Faith replied.

"You work for Hogwarts." The woman said. "Hogwarts answers to the Ministry."

"Madam Umbridge…" Dumbledore began before he was interrupted by Faith's laugh.

"That's a good one." Faith said and then saw Umbridge's expression. "Oh, you were serious. That's so cute."

Everyone was staring at Faith now, who simply shook her head in exacerbation.

"Sounds like it is time for a History Lesson. Ok, who knows when Hogwarts was founded?" Faith asked and looked around. "Weasley Twins, give it to me in Stereo."

"About 921 to 927." The Twins said in unison.

"Close enough. It was actually June 24th 924." Faith replied. "When was the precursor of Ministry of Magic formed? Granger?"

"1074 as a magical version of the Council of tenants-in-chief and ecclesiastics for William the Conquer." Hermione replied.

"Is there a point to all of this?" Minister Fudge said.

"The point, Minister, is that like Berwick Upon Tweed, Hogwarts and its surrounds are of Magical Brittan but not part of it." Faith replied. "In simple terms, for the Government Officials in the room, The Ministry has no authority over Hogwarts at all."

"And how would a simple Muggle like you know anything about such matters?" Umbridge asked with a sneer.

"I'm not a Muggle." Faith replied with a feral grin. "I am Faith Lehane, a Senior Slayer of the Council of Watchers."

"That means nothing." Umbridge said.

"Actually it means a hell of a lot, you stupid bitch." Faith snapped, standing up from behind the Teacher's table. "The Council is the arbiter of the King's Justice over the Magical Oath Breakers. It means I could break every bone in your body and the only thing that would happen is I would have to explain to my bosses why I felt the need."

"We are the Chosen, the superior." Umbridge declared.

"What did the Goblins do before the last so called 'rebellion'?" Faith asked.

"What does it matter? We defeated them." Umbridge countered.

"Just answer." Faith insisted.

"I believe they were craftsmen." Umbridge replied. "So what?"

"And now they control your economy and can cripple you by closing their doors. Sounds like they won to me." Faith summarised. "You don't even know your own history do you? You hid yourselves away because you were scared."

"Muggle's don't scare us." Fudge said.

"Not Muggles." Faith said. "The true enemy. The Demons. Magicals were created to help the Slayers fight the Demons, Oath Bound, but you Magicals got scared to fight, made lazy by the Magic gifted to you and hid yourselves away. Perhaps it is time we took the Magic back."

"Get her!" Umbridge yelled.

Two of the Aurors who had accompanied the Minister stepped forward and drew their wands. In seconds Faith was over the table and had disarmed the two Aurors, knocked them to the ground, grabbed Fudge by the throat and had a knife point millimetres from Umbridge's right eye.

"I will kill you if I have to." Faith said, her voice hard and level. "I have killed before, demons and humans alike. My Calling is to protect the World. If you get in the way of my Calling, you will die. I suggest you leave now."

Faith could clearly see the fear in both Fudge and Umbridge's eyes as she removed her hand from Fudge's throat. The Ministry personnel bid a hasty retreat.

"Minister Fudge will still make trouble." Dumbledore said once the Ministry people were gone.

"One second." Faith said, before pulling a phone out of her pocket and dialled a number. "Hey G-Man. If it's good enough for Boytoy then it's good enough for me. No, I didn't call just to piss you off. Minister Fudge-packer and a Pink Horror came by to try and kick me out. No, none of them are dead. Stuff it, English. I had to tell them off and give them a History Lesson. Threatened them with pulling their Mojo in front of the whole school. Nah, they're all listening. They look like they've never seen someone talk on a mobile before. Yeah well Red Mojo'd it, so it's cool. We're going to need someone to follow up. Think Red can arrange to revoke from Fudge-packer and the Pink Horror exclusively? Yeah well get the stuffies to look into it, cause I actually like some of these kids. Yeah I know. Say hey to B, X and D for me. Yeah, see ya."

Putting the phone away, Faith saw everyone was staring at her.

"You all have ten seconds to get back to your meals or we all go for ten laps around the Black Lake… at my pace." Faith announced.

In three seconds everyone, including the Professors, was staring hard at their plate as they ate. Faith walked back around the Teacher's Table, sat down, put her feet back up on the table and took another sip of her soup.

TBC…
