Harriet looked down at Luna, "Did I miss anything important Luna?"

"Glamours." The blonde replied, sitting up to be out of the way.

Harriet brightened a bit, "Ah yes!" She let her glamours fall, making her shoot up a couple inches in height. Her hair puffed out a bit as her feathers ruffled in agitation at the concealing magic being lifted. She ran her fingers through her wild hair and sighed happily, "Much better."

"What's with the hair pup?" Sirius asked.

"When Glacia forced the burn day I was still in human form, which led to this. We don't know if it will disappear on our next burn or not. Not only are ice phoenixes rare but people with magical animagi in general are rare." Harriet said with a bit of a shrug, "Its a guessing game. But I kinda like it." She settled back in her seat again, "So, questions?"

"So can we trust any of the Weasley's other than your mates?" Remus asked.

"Charlie for sure, Bill if we can get to him in time, but the others are either in on it or too attached to Dumbledore and Molly." Harriet said.

"I call in Curse Breaker Weasley to assess him." Griphook said, "He would be of great help to you moving forward." Harriet inclined her head in agreement.

"And what about Snivellus?" James asked, "I couldn't tell if he was working for Dumbledore or not from what you told us."

"Technically he's working for me, even if he doesn't act like it." Harriet said, "Dumbledore made him swear an oath to protect me when he came over from the Dark. He died at the Battle of Hogwarts not knowing he was being played by Dumbledore." She fixed all three of the Marauders with glares, "If I can bring him into the fold I expect you to be grown-ups and leave that stupid nickname behind, you aren't in school anymore and I won't tolerate bullies. A laugh is fine, bullying is not."

James blinked several times, "Dear Merlin you sound like your mother." Harriet's eyes narrowed and immediately James threw his hands up, "Fine, if you can bring him to our side I will do my best to act like an adult." Remus and Sirius nodded in agreement.

"Good, now I'm going to outline what I want to do in the next couple years but if you guys wish to remain ignorant and stay out of another war I won't fault you. I can stay at a LeFay property, no problem." Harri said, a bit nervous.

James softened, "Don't be ridiculous princess. I'm with you until the end. Whatever you need."

"Yeah Prongslet. You may be the focus of his plans but he screwed all of us over. We've got your back." Sirius added.

Remus nodded, "Pack sticks together."

Harriet let out a breath of relief, "Thank you." They all smiled at her and nodded. "Now I'm going to go over the basics of what I have and we can work to refine them as we go and as we gather more resources." She waved her journal, "This is the control book but I had the elves get me others that I will spell to copy and connect to this one so everyone will know what's going on." She looked to the Marauders, "This has the more in depth parts of the story, I ask that if there is something you don't like you come to me first, I won't let my plans be ruined because you want revenge for something most of these people haven't done yet."

James narrowed his eyes, "What exactly is in there that you think we may exact Justice, Marauder style?"

"Many things." Harri said vaguely, "I didn't have a pleasant next fourteen years and I won't pretend I did." She crossed her arms, "Now promise."

James crossed his arms as well and simply stared his daughter down until Remus jumped up and got between them, "We promise we won't exact revenge in a way that would jeopardize your plans."

"Moony!" Sirius whined.

Remus ignored him as Harriet considered this, "Fine." She said finally, "But if it interferes I will exact revenge." Remus nodded in agreement and shot James and Sirius warning glares. Harriet continued, "So, as I was saying everyone will get a book. The big over-arching plan that will take about seven years to complete is the gradual ruining of Dumbledore's reputation, that way if it comes to it again and he declares me a rising Dark Lady the requirements won't be met for him to claim conquest rights even if he does manage to kill me. The ruining of his reputation that I have in mind will eventually have people seeing him as worse than Grindelwald or Voldemort so that when I take him down and I will, that's a nonnegotiable fatality in this war, the people won't turn against me and attempt to put me in Azkaban."

"How?" Remus asked even as Sirius and James sat forward eagerly.

"Easy, running the kind of long scam he's doing is bound to leave trails and even an accomplished con artist leaves a few loose ends than can be tugged on. We need to work in the realm of facts though, we can't just come out of the gate accusing him. We have to have facts with attached irrefutable proof, then if he denies it he gets a reputation as a liar and if he doesn't the things brought to light bring him into more immediate question." Harriet said.

"You do have this planned out." Griphook chuckled, "How do you plan to start? We will need time to dig for things."

Harriet threw on her glamours and gave him a wide eyed innocent look, "Griphook, aren't you aware that poor naive little Harriet Potter is rejoining the wizarding world? She just won't know what to do if she is accosted by a certain Daily Prophet reporter when she is shopping."

Griphook grinned, "Why it may be disastrous for Dumbledore if certain things come to light, the worried citizens of the wizarding world were assured their hero was safe."

Harri dropped her glamours with a laugh, "And then after that blow we can oh so subtly dangle pieces to debase Dumbledore. And if we can get Skeeter on the payroll, even better."

Griphook nodded, "Find a way to send her to me and I will get it sorted."

Harriet nodded, "I'll more than likely do that next year after I've established a bit of an image for myself so that when people read about it they won't question my word. While that article is going out and the masses are reacting we will have time to go out and find proof of Dumble's other issues. So that's the big one at this time for the Headmaster, I have a few mini plans for him but that's mostly for my own enjoyment." She gave a small grin, "Now on to Voldie."

"The plan is to destroy all of the other horcruxes before fourth year then when he tries to resurrect himself I take him out completely. That actually works with the big plan as well because I can come back and say I defeated Voldemort and without knowing that we already took care of the horcruxes Dumbles will still try to say he's alive and coming back. The marks don't disappear immediately with his death, they just slowly fade out so that will work in our favor. Dumbledore will take every opportunity after that to say the Dark Lord is returning in an attempt to prepare the aurors and rally the people however with him truly being gone he will come across as crazy." Harriet said, reading over her plan, she looked up, "Questions? Comments?"

"Do you know the location of all the other horcruxes?" Sirius asked.

"Only most of them." Harri admitted sheepishly, "But the only two I'm unsure of is Nagini, because I'm not certain whether he made her one before or after his fall and the cup because when I tracked it down last time Bellatrix had put it in her vault and invoked an emergency seal on it. I'm not sure if it's there now or if she put it there after Voldemort broke her out."

Griphook raised a wispy eyebrow, "An emergency seal can't be undone by anyone but the one who placed it. How did you get the cup?"

Harriet blushed and looked away from the goblin, "I and my mates may have broken into Gringotts."

Griphook's eyes went wide, "And you survived?!" Harriet nodded, "How?!"

"Polyjuice and a stolen key to get past the front desk, fast reflexes to avoid the thief's downfall, specialized rune decoder to break the seal, temporary stasis powder to counter the gemino curse, and then an overpowered blasting hex to break the chain on the dragon so we could ride it out of the line of fire." Harriet said, shifting in her seat.

"You rode a dragon?!" James and Sirius exclaimed.

Harriet frowned, "It was just a little Norwegian Ridgeback. The Hungarian Horntail I outflew was three times that size."

"Miss Potter." Griphook interrupted, Harriet looked over to him nervously. "Gringotts would love to obtain the memory of that in an effort to shore up security in our establishment. What would the price of such an acquisition be?"

Harri breathed a short sigh of relief before smiling at Griphook, "It shouldn't be too much. Just the employment of Curse Breaker Weasley under your direct authority for a period of at least four years, he would be a wonderful asset to our team."

Griphook gave her a toothy grin, "I will have it drawn up the second I get back."

Harriet nodded, "And I will provide the memories in question when I receive the contract."

"You two are a bit scary." Sirius commented, Harriet laughed while Griphook smirked.

"As I was saying," Harri continued, "those two are the only horcruxes I am unsure of. However, Nagini will be at Voldemort's resurrection one way or the other and there are ways to allow Griphook to look into Bellatrix's vault that we can use."

She flipped a couple pages in her journal before stopping, "Okay, the Avengers plan. Right now they aren't a team yet, in fact most of them aren't aware of each other. Tony just became Ironman a few months ago, Steve hasn't been thawed out from the ice yet, Thor and Loki are in Asgard, Bruce is off in Africa somewhere, Bucky is still under Hydra's control, and Clint and Natasha are just SHEILD agents at the moment. Being who they are, they are all wary of new people so I will have to go with the slow approach for them, gain their trust and curiosity over time and from afar." Harriet said, "That plan has several phases that I won't be able to begin until I go shopping again. I only had the elves get my essentials and some of the stuff is muggle equipment that I will have to get myself."

"The two big plans in that grouping is saving Bucky and saving Loki," she sat back and crossed one of her legs over the other, "I wrestled for a good while on when to go extract Loki. I knew I had to wait until after Odin rejected him. I wanted to wait until he made a big ruckus at SHEILD and in Germany so we would know exactly how to how to stop the invasion, but Loki would have had to go through torture by the Other. In the end I couldn't wait, as with any of a phoenixes chosen, I will prevent my chosen pain when I can. So I have planned for me to go to Asgard and save Loki just as he's falling into the void."

"You can travel to Asgard?" Remus asked curiously.

Harriet nodded, "Loki showed me the secret paths between the branches of Yggdrasil and my flames can take me that far if I'm not drained or want to do it multiple times in a short period."

"Can we go with you?" James asked excitedly.

Harriet looked amused, "Maybe after I get Loki pardoned. When I go to get him I'll have to flame us away directly. Last time Thor told me about some Phoenix laws that would pardon me and excuse Loki but I don't know if he made those up or if they're real." James huffed but nodded in understanding.

"The plan for Bucky is hard and easy at the same time, hard because I don't know which Hydra base he's in and depending on that it may be harder to break in to get him. It's a bit easier because once I use legilimency to clear the mind control and help him assimilate and get past some of his nastier memories he will trust me a bit easier. At least that's how it happened last time. Again, for that plan I need some muggle equipment and probably won't attempt the break out until next year even if I can find him. I need time to build my body back to a state where I can maneuver easier." She looked around to see if anyone had questions but saw only understanding in their faces.

Harriet clapped, "Excellent, the only other set plan I have is taking my OWLs and NEWTs early so I can leave Hogwarts at any time should something go wrong."

"Leave Hogwarts?!" Sirius shouted, "You mean you're going back?! Even with all that's going to happen?" Harriet frowned and opened her mouth to reply but her dad jumped in.

"I won't allow you to go near Dumbledore again!" James said, jumping to his feet, "We can coordinate everything from here, but you won't go back to that school!"

Harriet jumped up to face her father, "I will NOT leave my mates there without protection! I will be going back to school, whether you like it or not!"

"No! Bring your mates here if you must but you won't go back!" James practically growled, "You won't go somewhere where we can't protect you!"

"If it was only my mates that were in danger I would but being there and keeping a cover will allow us insight into the other side as well as allows me to protect the other innocent students who will be in danger whether I'm there or not!" Harri argued, "As for you not being able to get to me, not only are you guys the fucking Marauders but two-thirds of you is considered dead! I'm pretty sure you can find a way into the school that you mapped out as a bunch of fourth years!"

James had no argument for that but was still blinded by his worry, "I won't allow it!" He repeated.

Harriet's eyes went icy and her face closed off, the temperature in the room dropped in seconds and the feathers in her hair started to shed blue flames, "I would like to see you try and stop me." She said in a deadly tone before spinning on her heel and stalking out of the room.

James went to go after her but Remus stopped him with a hand on his shoulder, "Don't." He warned.

Luna stood from the couch and walked over to face James, she waited until he looked down at her, "Worry won't help her. She's a survivor and she always will be. You all will be with her to help and protect her, you just need to clear the last of the Wrackspurts from your heads and get back to thinking like Marauders." She said before turning and following after Harriet.

Griphook stood and approached them as well, Sirius huffed, "Do you have save advice for us too?"

"No." Griphook said, "Just a warning. If you want to be able to stand with her then you better respect her decisions. She may look like a child but she is really a twenty-five-year-old who, by the sounds of things, had to grow up much to quickly and was basically a war general. Treating her as a porcelain doll who needs protected and decisions made for her will be the fastest way to drive her beyond your reach. Let me be the first to assure you that she has the resources to do so. Without your inheritances she already stands to inherit the Slytherin, LeFay, and Ambrosius headships before I leave this evening."

"LeFay and Ambrosius?" Remus questioned, "How...?"

Griphook straightened, "The late Lady Potter was the last descendant of the LeFay line, putting Harriet next in line and the Ambrosius was a surprise even she is currently unaware of. Merlin never had any children but she met the requirements that Merlin set forth for someone to inherit his estate, she will inherit it all." He folded his long fingered hands in front of him as he stared right at James, "I would let her cool off then go to her. She'll listen if your reasonable. She doesn't want to lose any of her family." He went to leave be before turning back to James, "Ah, I almost forgot. When Harriet said she was going to save you I took the liberty of retrieving this from your vault." He passed over a slim piece of wood, "Seems Dumbledore allowed it to be stored at the time of your supposed death as per Potter tradition." With that he left.

James stared down at his wand blankly for several seconds before groaning, "What did I do?"

"You were worried and overreacted." Remus said softly, "You'll have to apologize and try to explain why you acted like that."

"I just don't want her near that manipulative old coot." James groaned, "We won't be able to protect her if she's discovered."

"Griphook was right, she was and more than likely will continue to be a war general." Remus said softly, "She's probably got plans and back up plans and back up plans for the back up plans. She's not going to be caught easily."

"And we won't leave her by herself." Sirius said confidently, "She was right, we are the fucking Marauders! We'll be at that school with her even if we have to teach snot nose brats under glamours or de-age ourselves and go through school all over again!"

James started to relax and began to nod, "Yeah." A grin came across his face, "Yeah! We can do that! If she's going back whether we like it or not, we'll tag along whether she likes it or not!"

Remus gave them an indulgent smile, "Ah, I remember those scheming faces." James chuckled and flicked his wand to erect a privacy bubble around them.

Sirius grinned, "Hell yeah! Marauder planning session! Operation: Protect Prongslet!"

When Griphook left, he only had to walk back to the receiving parlor before finding the girls. Luna was hugging Harriet tightly from behind as she stood in front of the floo, clearly wanting to escape. "Miss Potter." Griphook interrupted, slightly uncomfortable with the emotional display.

Harriet flinched but looked up, "Oh, Griphook. I'm sorry you had to see all that. Emotions aren't very practical in business."

Griphook gave her a close lipped smile, "No they aren't Miss Potter but in a case such as yours I can understand how they will tend to creep in. As your manager I will attempt to separate the emotions in such instances so our time together will be profitable."

"It's much appreciated." Harri said, she squeezed Luna's arms where they were wrapped around her torso gratefully.

Griphook nodded, "Before I left to get things on my end started I wanted to make sure you got your Ladyships, heirships, and a report of all that will be available to you once you receive them. Are you ready to receive them?"

Harriet nodded seriously and watched as Griphook withdrew and resized six boxes which he sat on the table next to them, "Six?" Harri frowned, "I only knew of five."

Griphook brightened and actually looked excited, "After I read your inheritance parchment I found it, I assume you aren't aware of it so you must have completed the requirements before or as you left your last timeline." Harri raised an eyebrow at him and he picked up a carved wooden box and opened it facing her, "The House of Ambrosius. You have at some point between your last inheritance test and this one fulfilled the requirements set forth by Merlin, allowing you to inherit all he owned." Harri gaped at the ring in the box, it held a delicate silver dragon figurine that had a green stone on its back. "It's the same words used for the others," Griphook encouraged, "Just say them and offer your hand to it."

"I, Harriet Rose Potter, claim headship of House Ambrosius by my right as chosen descendant." Harri said, somewhat shakily as she offered her hand to the little dragon figurine. All three watched with wide eyes as the dragon shook awake and looked up at her with beady black eyes, after a few seconds it huffed before jumping from the box and onto the back of her hand. It walked down to her pointer finger and wrapped its tail around it twice before hunkering down with its wings over its head, holding the jewel in place and then going still. "Wow." Harri breathed as she felt strong magics wrap around her protectively.

"Indeed Lady Ambrosius." Griphook chuckled, he closed and shrunk the box before sliding it back into his coat. "Now for the others, I'm sure you remember how do claim them." Harriet nodded and repeated her words over each ring as it was presented to her. Only three did the words change but that was for Potter, Gryffindor, and Black, she just had to change 'headship' to 'heirship' for those three. Griphook put the last of the boxes away and looked back up to Harriet, "You are now Lady Ambrosius-LeFay-Slytherin, Heir to houses Gryffindor, Potter, and Black. How would you like to be addressed?"

"Lady LeFay for now Griphook. Let's keep the others close to us so our enemies may be surprised." Harriet said with a smile.

"Of course my Lady." Griphook said with a slight bow, he handed her four rolls of parchment, "These are the current holdings of each of your Ladyships as well as a more updated balance of your trust vault." He folded his hands in front of him, "Anything else you would like me to attend to before I take my leave?"

Harri nodded, "Take a sum of 200,000 galleons from the main LeFay vault and create a new one, shift the withdrawals that Dumbledore has set up to that one and monitor it closely. I don't like that their stealing money from me but I will give them a chance to be decent people and change their minds or I will take it all back from them at their most desperate moment." Griphook gave her a toothy grin and nodded, "Also, take 500,000 galleons from the Slytherin vault that receives the Slytherin share of Hogwarts tuition and have it placed in my trust to counter all of the supplies I will be purchasing. It won't make even a dent in that account." Griphook nodded, "Finally, take 10,000 galleons from the main Slytherin vault and have it find its way to your account to compensate you for the time you spent here today. Of course another 10,000 may find its way there as well when you have sent me the contract for Cruse Breaker Weasley."

Griphook gave her a surprisingly bright smile, took out a small book and wrote in it quickly. The book glowed green and he looked up at her, "The transfers are done. I will have to set up the new vault at Gringotts. The contract will be to you by lunch in two days-time as I need to coordinate with the Egypt branch." Harri gave him an understanding nod, "Will that be all Lady Lefay?"

Harri's lips turned up at the familiar line, "That will be all Griphook. May your gold ever flow."

"And may your enemies fall before your blade." Griphook responded before bowing and flooing out.

Harriet sighed and wriggled free of Luna's arms so she could give her a mischievous smile, "I think they've earned the right to fret a bit. Why don't we go ask your father if you can accompany me out to the muggle world for shopping and a bit of pampering?"

Luna gave her a wide smile, "That would be quite fun big sister."

Harri nodded, "Then let's go."

Next Chapter we meet Jarvis!
