Manipulative Dumbledore

Ravenclaw Hermione

Slytherin Rhea

Hufflepuff Ron

Neutral Malfoys

Rhea met Ron during the Zoo trip with the Dursleys. Ron fell asleep on a park bench and Rhea led him back to his family while conversing on muggles. Hermione and Rhea go to the same school and are friends.

Starts during the end of 2nd year. Rhea already has several allies in Slytherin and Ravenclaw. The Trio has a Grey standing in politics and magic. Rhea has the metamorphmagus ability from her grandmother's family and it was enhanced by her father's blood, a stronger version of charmspeak, and an emphatic ability. Hermione has an ability that can detect lies and half-truths, and force the target to tell the truth. Ron can create illusions that will put the target in a forceful sleep. James is Eros in his mortal form.

Pairings:

Ron/Nico

Hermione/Apollo

Rhea/Poseidon

Summary: After confirming their suspicions that their being manipulated by Dumbledore, the trio go to Gringotts to escape Hogwarts. They discover their godly parenthood and leave to train at Camp Half-Blood. Starts two weeks before Titan's Curse.


A/N: So chapter one has been rewritten because I did the math on when Titan's Curse started and when Chamber of Secrets took place. So that would mean when the demigod trio got to Camp Half Blood, it was in December. That would mean they would have to be on winter break, because winter solstice is on Dec. 22 of the year 2007. The demigod trio is still twelve although they are born 1995 putting them younger than Percy who is 14 at the time. 3/24/17


"Hermione, Ron there's something I have to discuss with you both. Ron can you put a spell on the door?" Rhea said to her closest friends

Ron warded the door with the golden power so if anyone wanted to come in they'd immediately go back to their compartment to sleep. Rhea had discovered something that infuriated her. It was about that old goat of a headmaster that she had suspicions about since she first met him. Her eyes darkened to a forest green. Seeing how serious she was Ron's eyes were open wide. Hermione put down the book on warding and looked at her.

Rhea took a calming breath before staring at her closest friends. When she had discovered these plans her magic had almost destroyed the room she was in.

"You know the suspicions I had on Dumbledore?" at her friends nods she continued "The goblins have confirmed my suspicions . But it's much worse than I feared. He's been taking money from my trust vault, he compelled 'Mione's parents to betroth her to Marcus Flint. And Ron he's betrothed you to me, so I stay his pawn. And that's just about our adulthood. He's planned our school years to." Rhea finished

This left both Ron and Hermione seething. Marcus Flint was a misogynist pureblood who only thought of women as brood mares. Hermione was not amused at this situation. Flint would not be able to mentally challenge her and she had no desire to be a housewife. Ron wasn't like his parents and Ginny. He didn't think that Dumbledore was the next Merlin. He was more in agreement with his brothers, the man was more like a grandfather who had too much power, or as Hermione suggested, Big Brother. Along with the fact that he had no desire to marry someone he considered his second sister. Both then looked questioningly at Rhea.

"So Rhea what do we do now?" Ron questioned

Rhea smirked at them both before telling them.

"Well I thought we could floo to Gringotts to undo all his plans. Ron I need you to send my relatives in a fitful sleep that'll look like they're having a seizure. With Mione's permission could you do the same thing to her parents. We then need to sneak away to Draco's parents since I've already informed them of what I need to do." Rhea finished

Both nodded and Hermione gave Ron permission to send her parents in a seizure like sleep. Two hours later they were at the station. Ron immediately sent the Dursleys and Grangers into a fitful sleep. All of the Weasleys except Ron rushed over to them along with a few muggles. Hermione, Ron, and Rhea slunk over to the Malfoy family and nodded respectfully to them. They grabbed the portkey and were sent directly to the Malfoy grand room.

The trio landed a little roughly but still on their feet. Draco stumbled a bit but played it off. Narcissa and Lucius landed gracefully and led them to the fireplace. Draco stayed behind and ordered some house elves to pick up his school belongings.

"Now you need to speak clearly while throwing the floo powder." Narcissa explained since Lucius had already walked towards his study

Rhea smiled a little before thanking Narcissa. Hermione had already grabbed the powder and threw it down while saying Gringotts. Ron went next and Rhea last. The experience was disturbing. Hermione had stepped out naturally while Ron stumbled a little. Rhea had tripped and fell into Ron. They laughed for awhile before composing themselves.

"One of these days you have to tell me how you got the Malfoys of all people to stand by you." Hermione muttered to Rhea

They went to an available goblin and waited. The goblin looked up expectantly when he finally finished his paperwork. Rhea was the one to speak.

"Excuse me mister but it there an accountant for the Potter family? My friends and I would like to do business with him." Rhea said in a polite tone

The goblin raised his eyebrow before signalling to another goblin and speaking in another language.

"Griphorn will escort you to Wurk's office." the goblin said

The trio nodded respectively before following Griphorn. They came to a regal looking office and stood before the desk where Wurk was sitting behind. He looked at them for awhile before nodding to them sit down.

"Ah Lady Potter are you here to discuss, what I have found from the audits today?" Wurk questioned

Rhea's face hardened before she spoke.

"Yes Wurk it we have little time before the Headmaster begins to search for myself and my friends.. I would like to request a emancipation for all of us." Rhea stated coldly

Wurk nodded his head before bringing out three parchments and a dagger.

"I need three drops of blood from each of you. It would help if we were to find relatives who would petition for your right to emancipation." Wurk stated

Ron went first and looked at his parchment. The dagger cleaned itself before Hermione cut her finger. Her eyes widened as she read her parchment. Rhea was last and looked at her parchment her eyebrows raising slightly.

Rhea's mind had shut down because she realized those names were Greek deities. Hermione wasn't faring any better.

Hermione was gaping at this. First her mother wasn't her mother. And she was somehow a Greek deity. Ron was just absently nodding his head.

Ron knew he wasn't like his siblings but he didn't think that Arthur wasn't his father. Ron's choked laugh brought Rhea and Hermione out of their brain fart. Rhea and Hermione soon joined in before they were all laughing. Wurk's cough brought them back to reality. He was reading their parchments with an eyebrow raised.

"I suppose that your parentage is unbelievable but I assure you that these aren't a prank." Wurk stated

Rhea nodded her head as she had noticed his curiosity.

"Yes we haven't had any demigods since the Founder's Era. And even longer for a demi-primordial. Yes I'll inform Fang to prepare an international portkey. You'll all be going to Camp Half-Blood to train your powers. Also while we cannot emancipate Mr. Weasley or Ms. Granger, we can emancipate you. You would be able to register them under Potter protection.

Rhea nodded her head in agreement. She would be able to free herself and her friends from Dumbledore's manipulations in one fell swoop. She smirked to herself and mentally gave thanks to her cousin, Narcissa for teaching her the art of politics.

"Of course that sounds like a wonderful idea. How quickly could you get me the papers?" Rhea asked

"Taking into consideration that you will be switching time zones soon. The fastest we could get it to you would be in two weeks, if you want this done as discreetly as possible." Wurk informed her

"That seems reasonable.

Ron groaned since that meant he had to be awake and moving. Hermione was excited because that meant she could learn from real myths that weren't myths. Rhea was very excited to meet her father since she never counted the Dursleys as relatives. The trio went to go get their belongings and familiars.

Rhea got her shrunken trunk and her five tailed fox "Cadmean vixen", a silver fox with sky blue eyes. Hermione got her trunk and her water phoenix "Hermes" an aquamarine phoenix with sea green eyes. Ron got his trunk and a lazy kneazle "Hypno" an earth brown cat with dull grey eyes.

"So we just wait until the portkey is ready?" Ron lazily asked

Hermione patted his shoulder to reassure him that he could sleep. Rhea was off in her own little world wondering how she would feel about her relatives. She couldn't believe it she could finally be free from Dumbledore's manipulations. She no longer had to live with those wretched Dursleys.

Wurk came back with the portkey and handed it to Hermione. He handed Ron the letter and lightly tapped Rhea. She shook her head and came back to reality. The trio grabbed the shoe while their familiars stayed on their shoulders.

"Give the letter to Chiron and tell him that Wurk sent you. And I've cleared the betrothals and we're pulling back all the money and possessions Albus has stolen from you. Good luck." Wurk said

The portkey was activated and the trio was off.

Wurk turned to Fang with an expression of worry on his face.

"I think we need to contact Ragnarok, inform him that three greek demi children are going to cause some major ripples."

Annabeth was patrolling the camp entrance under the invisibility hat. She was bored out of her mind. She hadn't seen Thalia since her last quest and Percy was spending time with his mother for winter break. She was getting ready to change shifts when three kids suddenly fell out of the sky. Annabeth was immediately on guard since nothing like this has happened before. The three kids hadn't noticed her presence yet so she observed them.

The first was a very short girl who looked to be at least 10 years old. She had unruly raven black hair that flowed down to her shoulders. Her eyes were an emerald green that changed color every now and then. On her shoulder was a silver fox with five tails. She was talking to a lanky redhead boy that seemed to be dozing off. The boy was leaning on a bushy haired girl who was grooming a golden bird that looked quite smug in her opinion.

Rhea looked around at her surroundings and tried to calm herself. She saw the entrance that said Camp Half-Blood in Greek. She took the letter from Ron and walked to the entrance. She noticed a hidden presence by the dragon but didn't seem to alert her friends. Hermione and Ron followed her as they looked for Chiron.

Annabeth was still wary of them but didn't think anything of it. When she revealed herself she was surprised when the trio didn't show any reaction. She shook her head and smiled at them.

"Hello welcome to Camp Half-Blood. I'm Annabeth, daughter of Athena. Did you not have a satyr?" Annabeth asked curiously

All three of them looked at her in confusion until Ron asked the they were all thinking.

"What exactly is a... um... satyr?" he asked through half lidded eyes

Annabeth almost laughed until she realized they weren't kidding. She coughed slightly to cover up her blush and continued leading them to the Big House. She knocked on the door and waited for Chiron to answer it. When he did Annabeth asked the trio to wait outside so she could explain their arrival. Rhea handed her the letter and asked could she give it to Chiron. Annabeth accepted and nodded her head.

"Ah yes Annabeth what is it?" Chiron asked

Annabeth gave him the letter and proceeded to tell him about the trio's arrival. When she finished her rant Chiron had already finished the letter.

"Hmm, I haven't seen any demigods from England in a long time." Chiron murmured to himself

Unfortunately Annabeth heard him and looked at him questioningly. Before she could ask he shook his head.

"I'm afraid I've sworn an oath that doesn't allow to disclose any information on what or who's in England."

Annabeth pursed her lips but nodded. Chiron stood up and walked outside to the new demigods. Rhea was the first to notice him. Hermione had to tap Ron awake as he had fallen asleep leaning on the house.

Chiron smiled at the trio and welcomed them

"Ah it's been a long time since I've been contacted by them in a while. Anyway do you know your godly parent? " Chiron said

Rhea nodded before responding.

"I'm Rhea the daughter of Eros, primordial of love and other things. Hermione is the daughter of Phoebe, Titan of intellectual I think. And Ron is the son of Hypnos, god of sleep and dreams I'm sure."

As soon as Rhea's introduction left her mouth three objects floated above the trio's heads. Ron had the symbol of a grey poppy. His outfit had completely changed into a dark red polo shirt with blue jeans and grey converse. Hermione's change was much more subtle. Her symbol was a dark moon with green mist around it. Her outfit changed to a more modest look with a loose fitting blue hoodie with blue converse and black jeans. Rhea's change was the most exotic. Her symbol was a purple heart with candles floating around it. Her outfit had changed into black skinny jeans, a emerald green shirt with a black leather jacket and black boots. Her hair had changed to a low ponytail and she had on red lipstick. Many campers had come around and were looking curiously at their entire change. Only children of Aphrodite got that type of claiming.

After that show both Annabeth and Chiron were convinced. Annabeth blinked owlishly before Chiron spoke.

"Well then, hmmh, welcome to Camp Half-blood."
