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 2

Thana entered her father's study, the anger still coursing through her, though not as much as it was before. She wanted to strangle the toad and goat or feed them to the Hounds. Unfortuanately, she couldn't. At least not yet. That thought lifted her mood a bit and she smirked. Oh she couldn't wait until her son changed sides or at least became neutral. She'd have to corrupt his friends too, but from what Harry told her, Hermione Granger, Ginny Weasley, Luna Lovegood, and the Weasley twins were tired of being pawns to the light side.

Snapping back to the present, Thana smiled at her father. "You wished to see me." she stated.

Hades nodded. "I found out something interesting today."

Thana perked up, interest lighting her eyes. "Oh?"

"It seems that a Tom Riddle split his soul numerous times." Hades exclaimed, looking at the papers in front of him.

Arching an eyebrow, the goddess stared. "Come again?"

Hades sighed. "Voldemort has eight Horcruxes."

"Eight?! Is he insane?!"

"Currently? Yes, yes he is."

Thana let out a breath, shaking her head at the idiocy of the wizard before a thought hit her. "Wait. How are you only now finding out about this? Voldemort is like, 70 years old."

" I may be a bit behind on paperwork. For the magical world at least."

Thana eyed him. "A bit?"

"Okay, very." Hades huffed.

Chuckling, Thana leaned against the edge of his desk. "So, should I go collect these soul shards?"

Hades nodded. "They have to be returned to the main shard as quickly as possible."

Thana sighed. "Well, I may as well start now. It'll help keep me distracted."

Hades blinked, finally taking note of the mild fury in his daughter's eyes. "What's on your mind?"

"The toad and old goat. I also may have came across two of my mates." Thana stated. Her vampire side had stirred when she had entered the Great Hall. She had suspicions of who they were and hoped that her son wouldn't be angry if she was correct.

Hades leaned back in his chair and smiled at her. "It's about time you found your mates."

Thana laughed. "Yes, well, I best be off." she said before disappearing in the shadows.

~Time Skip~

Thana looked around the forest as she headed toward where she could feel the Horcrux. Being the Grimm Reaper allowed her to feel and see souls, even soul shards. She could feel when a person was near death and when a soul was trapped in a dead body. It was her job to collect them and bring them to Charon so he can take them across the River Styx. She had ten apprentices, souls her father had allowed her to turn into Grim Reapers such as she. While Demetrius, Roseanna, Nikita, Ajax, Zeyphr, Adara, Nixie, Tristian, Maddox, and Ennis had the ability to remove a soul from a body, their powers only worked on dead bodies. Thana made sure of that. She didn't want any of them to get power hungry and start killing people who's time wasn't up yet.

A scent in the air made Thana pause as she snapped out of her thoughts. She closed her eyes and breathed in deeply as she came to a stop. She froze in shock. One of her mates was here. Her eyes snapped open just as she was suddenly roughly grabbed and pinned to a tree. A gasp of surprise left her lips and red eyes locked with her stormy grey ones. Dark brown, almost black hair framed a gorgeous, aristocratic face and pale skin glowed in the sunlight. Thana blinked. Her mate. Or one of them, at least. The man sniffed her neck and growled softly.

"Mate." he muttered, a hissing undertone to his voice.

Thana caught sight of fangs. One of her mates was a vampire. "What is your name?" she asked calmly.

The man pulled back. "I am Salazar Slytherin. And you, beautiful?"

Thana gaped before she started snickering. Salazar raised an eyebrow and stared at her in confusion.

"What is so funny?"

Thana coughed, a couple giggles escaping her. "Sorry, sorry. It's just that I can't wait to see Harry's reaction when he finds out one of my mates is Salazar Slytherin."

Salazar's eyes widened. "You're a witch? You do not smell like one." he said, sniffing her again.

Thana shook her head. "I'm not, my adoptive son Harry is a wizard. He attends Hogwarts as a Gryffindor."

Salazar's face twisted with distaste. "Gryffindor?"

Thana nodded. "Truthfully, he belongs in Slytherin, but he argued with the Hat."

Salazar smirked, pleased. "I see. You know, you never did say your name."

"It's Thana."

Nodding, Salazar stepped back, reluctantly releasing the goddess as he did so. Thana smiled at him.

"So, may I ask what brings you here?" Salazar asked, resisting the urge to grab her again.

"I'm looking for something. Care to join me?"

Salazar nodded, making her grin widely. She started walking again, enjoying the silence of the forest and fresh air around her, until she and Salazar came across a large body of water. The Horcrux she could feel was across the water. She turned the vampire next to her.

"Are you an animagus?" she asked.

He nodded. "Yes, I turn into a black mamba."

"Can you shift for me?"

Salazar raised an eyebrow, but did as she asked. She smiled and knelt down, holding out her hand. He slithered up to her and curled around her arm until he was wrapped around her shoulders. Rolling her shoulders, Thana felt her wings come free. The black bird-like wings spread out, the wingspan about 15ft, and some of the feathers looked blue or purple as the light reflected of them. Thana crouched down and leapt into the sky with a powerful beat of her wings. She soared through the sky quickly, seeing a cliff and cave in the distance. Flying there quickly, she landed on the rocks, her wings folding back and disappearing. Salazar slithered off of her and morphed into his human form. He eyed Thana with interest and curiosity.

"What are you, love?" he asked.

She sent him a wink and walked up to the mouth of the cave. The cries of trapped soul hit her and she stumbled back from the force of it. Se reached out with her senses and cursed.

"Inferi." she whispered with horror. Those poor souls.

Salazar's eyes narrowed. "Who would dare to create such beings?" he frowned.

Thana shook her head and looked into the cave again. Water. She needed to get the water out of there. After a moments thought she turned and walked to the edge of the rocks and knelt down. She put her hand in the water, aware of Salazar just behind her.

"Uncle." she whispered. "I need your help."

The water rippled, signaling that Poseidon was listening.

"The water in the cave, I need it gone."

Not even seconds later, the water in the cave slowly moved out of said cave. Thana sighed in relief and stood.

"Thank you."

The scent of the beach swirled around her in answer. Thana walked up to the mouth of the cave, fire forming in her palms. She threw jets of the flames into the cave, burning the Inferi. Getting rid off the fire minutes later, she held out her hand where a glass orb appeared, hovering. Seconds later, souls flew at her and disappeared in the orb until the cave was empty of the lost and trapped souls from the Inferi. Keeping the orb in her hand, Thana entered the cave with Salazar by her side. She approached the area she felt the locket in and found it in the ruins of some sort of glass or crystal. She picked up, looking up when she heard Salazar's sharp hiss.

"My locket."

Thana looked from the locket to her mate. "This is your locket?"

The red eyed male nodded in confirmation. "It is."

Thana sighed. "Your locket has been turned into a Horcrux by your descendent, Tom Riddle. He goes by Voldemort now-a-days though."

Salazar froze. "My descendent made a Horcrux?" he asked slowly in disbelief. "Using my locket?"

"He made several, actually. Now he's nothing more than an insane Dark Lord."

Salazar stared at her for a moment before sighing. "I need to catch up with the current history."

"I shall lend you some books. But first I need to drop off these souls. Grab my hand."

Salazar did so, twining his fingers with hers, and the two disappeared as shadows embraced them.

Charon looked up as he felt the presence of two others. He bowed his head when he saw his Lord's daughter. "Lady Thana."

Thana smiled. "Hello Charon. I apologize, but I have quite the number of souls today."

Charon raised an eyebrow. "Oh? Is that so?"

Thana responded by letting the souls free of the orb, which vanished once the last soul was out. Charon sighed when he saw them all. At least a hundred, if not more.

"Today will be a busy one." he remarked, dreading it already.

Thana patted his arm sympathetically. "You really should consider finding an assistant."

Charon nodded in agreement. "It may be best."

Thana sent him a smile before she grabbed Salazar and enveloped them in the shadows. Seconds later they were standing just outside of Hogwarts, where the last two Horcruxs were. Salazar stared at his mate.

"Who and what are you?"

Thana sighed. Now or never. "I am Thana, Daughter of Hades and Goddess of the Undead. I'm also the Grimm Reaper."

Salazar's eyes widened.

"I'm also part vampire, as my mother was a vampire queen, but that half merged with my god half when I became a full-fledged goddess."

"Y-you're a goddess."

"Yes."

"Merlin's balls."

Thana chuckled. "Come. It is lunch time and I wish to see my son before we continue our hunt."

"Our hunt?"

"The last two Horcuxes are here."

"I see."

Thana grabbed his hand and twined their fingers together as they entered the castle. As they neared the Great Hall, Thana frowned. One of the Horcruxes was coming from the Hall, though it felt...masked. She threw the doors open and strolled into the room. Like yesterday, everyone turned to stare. She noticed though, that everyone was staring at the man at her side. Thana's gaze locked at her son, anger and disbelief filling her. It was her son. The Horcrux was her son.

"Thana?" Salazar called to her softly, placing a gentle hand on her shoulder.

"My son is a Horcrux. How is it that I never noticed?"

Before Salazar could answer, Dumbledore walked up to them and Thana could see the hidden fury and fear. With amusement she realized that the old goat thought Salazar was Voldemort. Must be the red eyes.

"As Headmaster of this school, I demand to know why you are here." the old wizard stated.

Salazar eyed him with distaste, immediately feeling dislike for the man. "That is none of your business."

Dumbledore fought the urge to scowl. "It is as this is my school."

"I'd beg to differ."

Dumbledore's eyes narrowed. "Excuse me?"

Thana rolled her eyes and released Salazar's hand. She walked up to Harry, who smiled at her. She reached out and traced his scar.

"Mum?" he asked with concern and confusion.

"Come with me, Harry. It is urgent."

Harry immediately stood, grabbing his things. "I'll see you guys later." he said to his friends.

"They may come if they wish." Thana said.

Hermione, Ginny, Ron, Fred, George, and Neville were immediately on their feet, Luna soon joining them when Harry beckoned her over. Thana smiled at them and motioned for them to follow her. She walked up to Salazar, who saw staring Dumbledore down.

"Sal." she said. He looked at her. "Lets go."

He nodded, his red eyes shooting a glare at Dumbledore as the group left the Great Hall.

Okay, I hope you liked it. Thana is gonna end up with Ginny, Hermione, Daphne, and Salazar Slytherin.
