Harry Potter and the Goddess of the Undead

The idea for this story came to me when I was reading a Percy Jackson/Hp crossover.

Disclaimer: I don't own Harry Potter. If I did, Harry would be gay and with the Weasley twins or Tom Riddle and Sirius and Fred wouldn't have died. Harry and Ginny also never would have gotten together.

Warnings: Slash, femslash, possible harem for my oc Thana, AU, Dumbles/Ron/Molly bashing

Story starts in fifth year, sometime after the DA is put together

Pairings so far:

Fred/Harry/George

Chapter 1

The Great Hall was filled with chatter and laughter as its occupants talked and joked with their friends. Sunlight streamed into the large room from the windows and birds could be heard chirping happily. The Great Hall doors were suddenly thrown open, causing everyone to jump and turn their gaze to the entrance. A woman around 25 with waist length, inky black hair that fell down her back in elegant waves and deep stormy grey eyes strode angrily into the Hall. Her pale skin seemed to glow in the light and a scowl graced her delicate features. A dark red tank top clung to her upper body and black jeans to her legs. A black leather jacket was over the tank top and combat boots were on her feet. Strapped to her left thigh were four deadly looking daggers and hanging off a sheath on her waist was an equally deadly looking sword. Danger radiated off her and the students and staff stared. The woman's eyes ran along the staff table, stopping on Dolores Umbridge with a sneer.

"You!" the woman hissed venomously.

Thana glared at the toad like woman with barely concealed fury and disgust. This was the woman who dared harm her son? Said woman eyed her with contempt while the rest of the staff eyed her warily. Who was this woman and why was she so furious?

"Who the hell gave you permission to use a blood quill on my son?!" Thana hissed dangerously.

Umbridge paled and gasps echoed throughout the Great Hall. "I have no idea what you are talking about." she said in an overly sweet voice. Despite her words, a spark of panic flashed through her eyes.

Thana growled, sneering. "I'm sure you do, toad."

Umbridge scowled, glaring. "You will speak to me with respect. I am the Minister's Under Secretary." she snobbishly stuck her nose up in the air, eyeing Thana with a 'holier than thou' gaze.

Thana barely refrained from rolling her eyes. "I'll speak to you with respect when Hell freezes over. Now, I'll ask again. Who do you think you are using a blood quill on my child?"

"I have done no such thing." the toad like woman said with a sniff.

Thana's glare went colder. "Answer truthfully or I wont hesitate to feed you to my father's favorite pets."

Dumbledore stood. "That is enough. Who are you and how did you get through the wards?"

Thana eyed him with barely concealed hate. "Shut it, you old goat. You're no better than she is."

Fury flashed through Dumbledore's eyes before it was quickly hidden and everyone gaped at the woman who dared to disrespect the Great Albus Dumbledore. The Slytherins smirked, rather enjoying the show that was going on. Before anything else could happen though, Harry Potter stood up, much to the confusion of everyone else.

"Mum! Stop antagonizing the staff." he called to the dark haired woman.

Everyone gawked in surprise. This obviously dangerous woman was Harry Potter's mother? How? Thana turned and smiled at her son, warmth in her eyes. She strode to him quickly and pulled him into a tight hug, which he returned happily with a grin.

"I assure you, it is all well deserved." she said, pulling away.

Harry chuckled. "Whatever you say, mum." he retorted. "Why are you here?"

Thana narrowed her eyes at him. "You know why. One year. You can't go one year without trouble following, can you?"

Harry shrugged. "I've accepted it."

Thana's eye twitched. "I've had half a mind to pull you out of this bloody school, you know, but you friends are here so I won't. Now, your hand."

Harry sighed and held out his right hand, wincing slightly as a jolt of pain shot through it. Thana eyed the cursed words with disdain and gently grabbed the hand, swallowing her anger. Oh how she wanted to give that woman over to the Harpies and watch as they whipped the flesh off her bones.

"Blasted woman." she grumbled, raising her other hand, where dark red fire sprouted from her palm, making the people watching gasp with awe.

Touching the wound with the fire, the flames seeped into the cuts, eating the curse. Seconds later the fire disappeared and Thana conjured a cup of liquid nectar and ambrosia. She handed it to Harry.

"Drink." she ordered sternly.

Harry immediately complied, downing the liquid in two gulps, moaning softly at the heavenly taste. Once the liquid was gone, the cup disappeared. The wound on Harry's hand healed, leaving behind untouched skin. Thana nodded in approval and kissed his forehead softly. Turning, she marched back to the staff table and glared at Dumbledore.

"If Harry is harmed again in this blasted school, I'm transforing him to Beauxbatons." Thana declared.

Dumbledore looked smug for a moment. "You don't have the authorization to do that, as you are not family, I'm afraid."

Thana fought the urge to smirk. "Harry is my son. I legally blood adopted him when he was 6 at his request."

Dumbledore's eyes widened in shock and fury. His plans were crumbling to dust. He was losing control over his weapon. It didn't help that the boy was losing trust in him and Ron Weasley.

Suddenly a beeping noise came from Thana's pocket. Taking out her cell, she sighed when she saw the text from her father. Putting the phone back in her pocket, she walked back over to Harry, who was once again seated. She placed a kiss on the top of his head.

"I have to go. Your grandfather needs me."

Harry nodded. "Kay. Have fun." he kissed her cheek.

Thana grumbled and walked out of the Great Hall, muttering under her breath about toads and old goats. Harry went back to eating, pausing when he saw everyone staring at him.

"What?"

Most of the students looked away.

"Harry," Hermione started hesitantly. "Who was that?"

Harry eyed her. "My mum."

Ron blinked in confusion. "But your mum is dead."

Hermione elbowed him sharply with a glare. "Ronald!"

Harry rolled his eyes. "Thana blood adopted me when I was six."

"Bu-but what about the Dursleys?" Ron asked in confusion.

"I don't actually live there, mum just made it seem like I did."

"Where do you live?"

Harry sighed in slight annoyance. "Do I really have to answer all these questions now?"

Ron nodded while Hermione shrugged.

"Fine. I live with my mum and grandparents in my granddad's castle."

Those that heard gaped with shock. Ron paled.

"C-castle?"

Harry nodded. "Yeah."

"You know Harry, your mum is bloody hot." Seamus suddenly said, eyes slightly glazed over. Nobody had to guess to know what the Irish teen was thinking about.

Harry blinked. "O-kay." he eyed Seamus weirdly.

Hermione was about to ask something, but decided to wait until she and Harry were alone. She was curious about her best friend's mother and wondered if she was the one to warn Harry that Dumbledore was using him as a pawn. Most likely, thought Hermione, her thoughts racing.

Harry sighed in annoyance as Ron kept badgering him about his mum. Was it to much to ask for peace and quiet? Beside him, Hermione and Ginny were also looking a bit annoyed with the redheaded male. The two females were trying to work on their essays, but couldn't focus. Finally having enough, Hermione exploded.

"Shut up, Ronald! Leave Harry alone. When he wants to answer your questions, he will." she exclaimed.

Ron turned red. "I'm just curious is all." he huffed.

"We all are-"

"-little brother."

Fred and George plopped down on either side of Harry, who smiled at them.

"Tell us Harry, what is this-" Fred started.

"-mother of yours like?" George ended.

Harry, seeing the genuine curiosity in their eyes, decided to answer. "She's brillient. She's actually like all the houses in one."

"What do you mean?" Ginny asked.

"Well, she's very cunning and ambitious, she's brave and has courage, she's loyal and hardworking, and last but not least she's extremely smart."

"What else?" Hermione asked, interest clear in her eyes.

Harry smirked. "She loves pranks."

Fred and George immediately perked up. "Pranks you say?"

Harry nodded. "She also loves art and music. You should hear her play the piano or harp. She can sing really well, too."

"She sounds amazing." Ginny said, a dreamy look in her eyes.

The twins rounded on her.

"It looks like our dear sister-"

"-has a crush on Harry's mum!"

Ginny immediately flushed red. "I do not!" she denied.

Harry laughed. "It's okay Gin. I give you permission to go for her." He knew Ginny was a true friend and didn't cringe at the thought of her and his mother together. It'd be weird though, as Ginny is younger than him. But he had a feeling Ginny would become very important to his mother.

Ginny's eyes widened. "Really?"

Harry nodded. "Mum is single, and I know for a fact that she swings both ways."

Ginny couldn't help but beam brightly at him.

Okay, I hope you liked it. Truthfully, I don't know who Thana is gonna end up with. It's between Ginny, Hermione, Tom/Voldemort, Sirius, Bellatrix, Lucius and Narcissa, or Severus

I'm also considering a harem of four/five
