"Very well. Moody? You'll need to use a ratioostium potion to allow the changes to be absorbed, before using rescribere. If you're changing that much about them, I suggest taking a full alteration kit, empty what you don't use into a conjured bowl and banish it when you're finished. Don't give anyone, anything to speculate about what you might have done. You'll also need to create backgrounds, not just for them but for their parents. Take a few identity confirmation kits and make sure setting the changes." Moody nodded in response to Scrimgeour's directions. "And for Merlin's sake, don't forget to get their papers backdated, lodged and obliviate the WFS people, before you let them go."

As Moody locked the box down again after Scrimgeour left, Sirius smirked at Harry, which was a bit pointless as Harry and Sirius still wore blurring charms. "That was brilliant, pup. Everything you told him was the complete and utter truth, but the big picture you gave him was considerably different than what I remember."

"Well, the hat did say I'd do well in Slytherin." Harry replied innocently, leaving Sirius to gape and Moody to roar with laughter.

"He's got you there. Now, enough with the patting yourselves on the back, we've a shitload of planning to do. Starting with this…" He slapped down a thick file on the table. "Now, we've two options to choose from, do we do the planning here or do we go elsewhere…" Something occurred to Moody. "For that matter, where have you been staying?"

Harry laughed. "Forest of Dean. One of the first things I did was to buy myself a tent and I've been there since. Wanna come and have dinner with us?"

"And you can explain to Harry just exactly what's involved in a permanent overwriting process." Sirius added.

"That I can do." Moody picked up the file and tucked it away into a pocket. "Maybe better get a couple more of these…" Moody huffed. "Might need 'em."

"Don't suppose Harry and I can visit Borgan and Burkes? I need some better matched wands." Sirius said hopefully.

Moody gave Harry a narrowed glare. "Borgan and Burkes? What the hell were you doing down there?"

"Getting a wand." Harry answered, matter-of-factly. "Oh, get over it, no one knew I was there, I followed Malfoy when he went to get rid of… I think it was a dagger and a necklace… I was under my invisibility cloak the whole time, geez, Moody I'm not stupid." Harry snarked.

Moody just looked at the two of them. "You two are going to drive me grey, you know that, right? And yes, Nigel, we can go to Borgan and Burkes."

"Why are you still calling me Nigel?" Sirius whined.

"Because you don't like it and we don't need people knowing who you are." Moody ended the box's lockdown and lead the two out. "You need a new wand, something to move forward with, something experienced. I think… Some minor glamours and we're heading for the alley."

"Might check Borgan and Burkes, Mad-Eye." A new voice said. Turning Harry and Sirius saw a much younger Kingsley Shacklebolt.

"Uh." Moody grunted. "Yeah, they've a good stock. "We'll head there first, then we'd best find somewhere to get some research and planning done."

"Need another set of eyes?" Kingsley offered.

Moody looked at him, steadily. "I don't think so, but if that changes, I'll call ya." The older Auror told the newly graduated young man.

"Right." Kingsley nodded and headed back to his desk. He knew better than to push, but he'd made the offer.

"Come on, you two. Let's go." Moody lead them from the DMLE and out of the Ministry, via the DMLE's restricted access. It was a portal that lead straight to the junction of Diagon and Technic Alleys.

"Over here." Harry lead them to the tiny alley between WWW and the bootmaker's and up the stairs, he paused at the top of the stairs to key them into his semi-permanent notice-me-not on both the stairs and the rooftop.

"Whoa, pup. That's some serious spell-work, there. Where'd you learn that?" Sirius asked.

"It's not something that's taught at Hogwarts." Moody agreed.

"The Black library, Siri. Mione, Ron and I camped out there for nearly two months. And you know Mione." Harry answered.

"Let me guess, first thing she did, was hit the library?" Sirius sighed.

"Second. First was checking for other people." Harry corrected.

Sirius blinked and Moody snorted.

"Smart girl." Moody nodded approvingly.

"You have no idea." Harry shook his head in amusement. "But I've got a question? Our wands? If you're going to change our cores, won't that mean that our wands aren't going to match us anymore?"

"Normally, yes." Moody answered. "But once you've both got a quartet of wands, we'll see about blood-bonding them to you, during the alteration process. Your own blood is introduced into the wand as an additional core, but the process actually links the blood in the wand to you, any changes that happen to you that affect your blood will affect the blood in your wand."

"Oh…" Harry exclaimed, almost silently.

"It's Auror standard procedure." Sirius nodded. "Well, the blood-bonding is, but the four wands bit, that's just Moody. Most Aurors only have two." He shrugged.

"But I've already got two." Harry said.

"That's fine, pup. Most people come into the program with one or two." Sirius assured him.

"So, going to Borgan and Burkes to get two wands for me and three for Sirius? That' not going to stand out?"

"Nah…" Moody drawled. "We'll be getting Black four wands. We just tell Borgan that the fourth is a better match than his existing, if we get better matches. If not, there are a few other places we can go. The Junk shop on Quaffle Row in Dublin, Harbisher's on Pegasus Court in Glasgow, Dervish and Banges' on Castle Drive in Hogsmeade and Littleford's in The Harpy's Square in HolyHead. Plus, the DMLE has a small collection of wands, mostly those that were somehow involved in a case and all parties are deceased. It's a last resort and not recommended."

"Right. Borgan and Burkes it is." Harry sighed.

"Glamours?" Sirius asked. Harry smirked and focused on his older appearance, before casting the Auror level charm. "Whoa, pup, nice." The Animagus nodded his approval.

"Who taught you that, Pot- Ewan?" Moody grunted.

"A young Auror who is in her… fourth…fifth… no, fourth year at Hogwarts, right now." Harry answered.

"Fourth year?" Moody grunted. "That's a bit young to be teaching you, isn't it?"

"She was one of my Order guards, we got a bit bored sitting there just staring at each other, so she tried to send a tickling hex at me, I sent it back and... things escalated. You were the one to tell her to 'teach him, just keep him busy', you're damned lucky she didn't try something else. I was a fifteen-year-old boy, after all."

"Ugh…" Moody grunted. "Enough. I'll take you, one at a time for Borgan and Burkes'. Who's first?"

Harry and Sirius looked at each other.

"I've already got two wands, Siri. You need a decent match, you go." Harry said.

"And what're you gonna do?" Moody grumbled.

"I'll head down to Scribulus', again, and get some parchment sheets, some ink and…" He paused. "Maybe I should go into muggle London and get some pens?" He mused.

"Scribulus sells fountain pens, pup. Get a couple of them." Sirius told him.

"I can do that. Then, I'll come back here and get started on some notes. Names, backgrounds, that sort of thing." He looked at Moody. "Unless you want me to go pack the tent up?"

"Where is it?"

"Forest of Dean." Harry answered.

"It's one of Carson's?" Moody asked.

"Yeah."

"Get the tent, bring it back and put it up, here. Your protections will keep it hidden and the ambient magic from the alley will mask anything we do." Moody directed. "We should be back in an hour or so. Then I'll take you."

"You do realise, I can take myself? Don't you?"

"Not if we want Borgan to think this is just a trainee intake." Moody corrected.

"Point." Harry sighed. "Off you go, then." He apparated away hearing Moody mutter about 'bloody Potters'.

The three sat watching the sunset over London, from the comfort of their armchairs. The remains of a hearty meal on the conjured picnic table, in front of them.

"So, going to tell me what's involved in using the potions that Scrimgeour mentioned?" Harry asked Sirius.

"Not me, pup, I never had to learn." Sirius answered.

"No, he wouldn't have. Only the few Master Aurors and our Potions Masters, know about the potions and what's involved in using them." Moody said. "That's only… what… six of us? Seven?"

"Alright. What is involved?" Harry wasn't going to be dissuaded.

Moody sighed. "The process… it's complicated, but at the same time, it's fairly straightforward. We'll work out who you are going to be, then work our way backwards from there, in as much as parents and grandparents, etc. Once we have a family tree done, we start with the actual alteration process." He lifted his flask to take a sip. "First is the ratio ostium.That allows any changes we make to you to be absorbed into your core. Then, you take the rescribere, any changes you want are made, at the end you take a setting agent and the changes become permanent. There's a little more to it, but that's the simplified version." He snorted. "I notice that you primed Scrimgeour. My grandsons. You know damn well I don't have any grandsons. What's your plan?"

"We don't have to be your actual, blood grandsons, but it'd be more believable that you'd keep grandsons or foster-grandsons off the Ministry's detections net." Harry said. "We haven't' worked out what relationship Sirius and I are going to have to each other, or to you. But it seemed like too good an opportunity to miss." Harry answered.

"What are your options?" Moody raised an eyebrow.

"We've three options, Sirius and I, that is. One, father and son. Two, Uncle raising an orphaned nephew. Three, brothers." Harry answered, while Sirius climbed to his feet and headed for a bathroom.

"They'd all work. Let's take each one and breakdown what's needed." Moody summoned his coat and pulled out the wad of parchment. "Right. Option one, father and son. Id's for son, father, mother and grandparents. Option two, uncle and nephew. Same, plus Id for uncle. Option three, brothers. Id's for brothers, father, mother and grandparents." Moody waved and the parchment began to take notes. "Amounts to much the same. However, if you really want to be my grandsons, that eliminates the need to create Id's for mother and anything on the maternal side." He hummed. "And I've thoughts on some of the paternal side, too. Let's wait for Black to get back."

When Sirius re-joined them, Moody nodded and began to explain. "Potter mentioned your options, I've got possibilities, if you were to go with the third option, being brothers."

"Go on." Sirius sipped at his bottle of butterbeer.

"Depending on the age you want, my daughter is a possible mother, certainly for Potter, as his right now. For the father? Yeah… I've got a few possibilities, there. The clearest is to create a father via Id-golems."

"Id-golems?" Harry asked.

"Yeah. Id-golems can be used in two ways, one, introduce a blood sample into the golem and use it as a version of the person who provided the blood. Or… use the golem to create an Id from scratch, using blood replacement potions and magical birth-certificates." Moody explained.

"So, if we left you free reign to sort that out, what would you do?" Harry wanted to know.

"About parents?" Moody asked and Harry nodded. "My daughter Laura…"

It took the three males, two days to hash out all the finer details. When they were done with the planning, it was time to act. And that meant interacting with the DMLE's Potions Masters that also doubled as their ritual specialists.

"And they'll be obliviated afterwards?" Harry asked, feeling more than a touch paranoid about the Unspeakables finding out what had happened to he and Sirius.

"Yes, lad, I'll be doing it meself." Moody said for the fifth time. "Now, come on. In here." Moody lead them into a small office. "This office is nothing more than a front. Everyone in the DMLE knows the floo here is connected to our safe houses, but only a few of us know that it's also connected to the department's specialist area." Instead of leading them to the floo-fireplace that was the prominent feature of the empty room, Moody lead them to a small built-in cupboard. He opened the cupboard and tapped a section of the cupboard's ceiling, and one wall slid away to reveal a second floo-fireplace. "This one has only a single destination. Just toss the floo-powder down and let it do its job, no need for speaking."

Thirty seconds later, the three stood in one corner of a very large room, Harry guessed it to be bigger than Hogwarts' Great Hall. Also in the room were two unknown people, a witch and a wizard, and Scrimgeour.

"Boss?" Moody asked.

"I'm not staying, but I needed to sign-off on this, Alastor. When I'm gone, they can drop the glamours and let Sarah and Michael get to work." Scrimgeour nodded to the, as yet, unintroduced couple and after signing another piece of parchment, he headed for the floo. "Good luck, you two." He said as he passed Harry and Sirius.

"Thank you, Director." Sirius bowed slightly as the man walked around him.

Scrimgeour didn't say anything but he paused and returned the bow. Harry hadn't said a word, but he did nod to the man before joining Moody.

Moody, in turn, waited for Scrimgeour to floo away before speaking to the two specialists. "Morning, Sarah, Michael."

"Moody." The pair spoke together.

"What're we doing? Scrimgeour just said that he was authorising whatever you needed." The wizard, Michael, said.

"We're doing the lot, but we're adding a setter. This is to be permanent." Moddy answered.

"Permanent?" The witch, Sarah, raised a brow.

"Permanent. Irreversibly permanent." Moody clarified.

"Ooh, now that's something we don't do every day." She whistled quietly.

"So, the lot then?" Michael asked.

"Almost. New Id's for them and part of their paternal side. The maternal is existing. And some of the paternal are deceased but existed." Moody corrected.

"That could be a problem, Moody, living relatives and new Id's rarely mix well." Michael objected.

"Not this time, Michael, family are fine. Already consulted and good to go." Moody huffed.

"If you say so." Michael sighed. "Alright you lot, over here." He made a 'come with me' gesture and lead them to a series of free-standing noticeboards. "This is where we'll lay out the information and create your family history. Moody said some of them were existing, the maternal side. We'll start here with great-grandparents. Do we have any of them?"

"We do. But I can shorten the process, I have a blood donation, willingly given, for their mother. My daughter, Laura. And for some of the paternals."

"Oh, well, that explains why you said family are good to go. That will shorten it. Here, let me get you an Id-golem." Michael pulled out a specimen jar that held what looked like a cross between a jellyfish and lump of pale pink chicken breast. "This is an Id-golem." He told Harry and Sirius. "It's a potion-created chunk of human flesh. Kind of gross. But it's blank as far as genetic material goes. We have to inject it with human blood, willingly given, for it to become usable. We'll enlarge it and add some blood replenishing potions and soon enough, we'll be able to take enough blood from it to use in the ritual to create a new Id."

"What if you don't have blood?" Harry asked.

"Ah, then we have to use a blood replacement, a blood quill, a dragonhide gauntlet and a magical birth certificate." Sarah answered. "As we'll also be creating part of your paternal line from scratch, you'll get to see that, soon. For now, let's work on the maternal side."

While Sarah was answering, Moody had handed over a large-ish phial, it looked like it would hold about a cup of liquid, to Michael, who carefully placed it on a table, before pulling on a pair of tight leather gloves. Then he opened the phial and using an equally large syringe, drew up as much blood as the syringe would hold. Then the specimen jar was opened and the blob of flesh, lifted free. Michael held the blob, while Sarah injected it with the blood, them Michael let it slide back into the jar.

"That will take a few minutes to be absorbed, so let's see about the paternal side. What have you got for us?"

"Great-grands. Father's grandparents, paternal side." Moody held up a pair of phials strapped together. "Marius Altair Grimm, born Black and Beatrice Mary Caldwell."

"Black? Moody are you out of your mind? The Blacks won't accept that." Michael objected.

"Marius was disowned for being squib, Michael, the Blacks have no claim over him or his descendants." Moody explained.

"Oh… that's different then." Michael blinked. "Okay." Two more blobs were retrieved and injected with blood. Then on a board that was divided and labelled like a blank family tree, Sarah began to fill in spaces, but instead of names, she used numbers. Under 'mother' was the number '1', while '2' and '3' much higher up on the paternal side.

"Well, that gets us started, anyway." She nodded. "So, all we need to do now is fill in the gaps."

Half an hour later, the family tree was complete, names had been added and they were ready for the next step.

"Okay, so how old are we making you two? Please be aware that we can de-age someone, but we can't increase their age." Sarah warned. "There are potions that will do that, but we consider them to be unsafe and unreliable."

"So, the DMLE won't allow them to be used." Michael added.

"That's fine." Sirius assured them. "We've thought about this pretty seriously and we've decided on a date of birth. 1stof April 1978."

"For both of you?" Sarah asked.

"Yeah. Twins. Fraternal, but similar enough to get mistaken for identical at first glance. We want our eyes to stay the same as they are now. Everything else is negotiable." Sirius answered.

"Right. We can do that." Michael grinned. "So… the first thing we're going to do is… ratio ostium potion. Here, one each, down the hatch, lads." He handed over two small phials of clear liquid and after sharing a glance, Harry and Sirius swallowed the contents. "Excellent. Now, let me set the date on these." He began to chant over another pair of phials, this time containing a pale green liquid with blue swirls. When the swirls became a spiralling vortex, one significantly darker than the other, Michael them on the table. "The darker one is for you." He slid one phial towards Sirius. "And the other is for you." The second phial slid towards Harry. "The darker the potion, the stronger it is and the more it de-ages you. And we're only taking you," he pointed to Harry, "back a few months." He explained and waited until the empty phials were back on the table. "Excellent. Sit there for a few minutes while the de-aging stabilises. It shouldn't be too long. Next are the genetic overwrite potions, one for maternal and a second for paternal." Two pairs of bottles were placed on the table, each pair made up of a dark blue potion and a dark reddish-purple potion. "Drink the lot, but feel free to take your time. These won't affect you until we activate them and that's not going to be until at least, five minutes after you finish drinking them."

Harry watched as Sirius began to de-age, for some reason, the fact that the whole process took minutes, instead of seconds, surprised Harry.

"While we're waiting, bring your wands out and we'll get them linked to you." Sarah added. "We're going to have to get someone in, for that, but she's agreed to be obliviated, by one of you, so once we're done here, it will be irreversible." She didn't wait for an answer, but headed for a small door, that neither Harry nor Sirius had noticed. She returned with an older witch, not as old as Dumbledore, but not that far from it. "This is Madam Woodley. She'll be treating your wands, today and I'm going to let her explain what she plans to do and what's required of you." Sarah stepped back and went to work alongside Michael, mixing potions and using syringes.

"Gentlemen." Madam Woodley nodded to them.

"Madam." Harry and Sirius nodded back.

"Madam Woodley. Thank you for coming." Moody nodded.

"Auror Moody, how far am I taking this?"

"Treat them the same as any other graduate." Moody directed.

"Both graduates?" She asked. "Undercover?" She looked at the shrinking Sirius and the already small Harry.

"No and I hope that neither of them enters the corps." Moody answered. "Protection program."

"Ah. But you still want them to have their wands treated?"

"Yes."

"Very well." She turned from Moody to Harry and Sirius. "Gentlemen, what I shall do is combine all of your wands into one staff and link that to your blood, then I shall divide the staff back into wands. This means that each wand will be exactly the same as the others. The same timbers, the same cores and all with direct access to your core. Shall we see what I have to work with?"

Harry and Sirius both bit their lips, tongues or cheeks to refrain from commenting, but both began to pull wands out. Sirius flicked his at Harry and shrunk his clothes to fit his slightly younger body and then did the same to shrink his own wizarding robes to fit his much younger body. They were going to have to go clothes shopping, after this. Sigh...

"Hmm… One at a time, I think. You first." Madam Woodley held up a hand to stop them from putting all their wands on the table at once and pointed at Harry. He nodded and laid his four wands out, side by side, on the table. "Interesting, interesting. Acacia, subspecies Spear Wattle. Silver birch. Ebony. African Blackwood. And what of the cores? Hmm…?" She muttered, but it was clear that she wasn't asking Harry, as all her attention was on the wands. "Horned Serpent heartstring. Basilisk venom. Griffin Heartstring. Unicorn blood, willingly given. Phoenix tears, willingly given. Occamy shell, powdered. Thunderbird claw. And Snidget feather. A very interesting combination." She pulled a pair of rune-covered gloves from a pocket and put them on, before picking up two wands. A few minutes of chanting and Harry watched as the two wands melted together to form a longer, thicker wand-shape. Then a third wand was added, followed by a fourth, until Madam Woodley was holding a short staff.

"Now, young sir? I need you to cut your hand and clasp it around the staff. And don't let go until I tell you to."

Harry nodded and held out a hand to Moody, a swipe with a knife and Harry's palm was cut from wrist to fingers. He held out his bloody hand and Madam Woodley lay the staff across his palm and watched carefully as he closed his hand around the staff. She nodded and began to chant again, and Harry could feel the wand pulling at his blood and core. It lasted only a few seconds, but he felt lightheaded when it ended.

"Well done, let go, now." She ordered and Harry let his hand fall. He leant against Sirius and shook his head to clear it. More chanting and the staff once again melted, this time it slid into two pieces, then each of them melted into two. Madam Woodley let the wands slide from her hands to the table. "There we are, lad, four identical wands, all linked to each other and to your blood and core. They'll not work for anyone not of your blood. Those that share your blood? Well, it depends on you. If you hand them the wand, or throw it to them, with intent for it to work as well for them, as it does for you? It should. If they just pick up the wrong wand, it may work, but not to the same degree. I would suggest adding a focus stone to each wand, it will enhance your accuracy with intricate spell-work and aiming for duelling. It will also serve as an identification means, if your wands are placed with someone else's. For you? I'd recommend a peridot or chrome tourmaline. I can do that, or you can take it to any wandmaker of your choice to have it added."

"Do it." Moody answered for Harry.

"Certainly, that will take only a few moments." She pulled out a small box, laid it on the table and enlarged it. The front folded down and the top folded over and away and Harry saw row after row of tiny drawers, stacked ten high. Madam Woodley opened one and slid it onto the table. "Run your fingers over that and pull out five stones."

"Five?" Harry asked, but did as he was told.

"Five. I'll need to blend them together, like I did with the wands, before splitting them apart, otherwise they won't be identical." She answered. Harry handed her five different stones, three dark and two paler. "Ah, thank you lad." A few moments of chanting and four stones sat on the table. Madam Woodley pickup one stone and one wand and set the tip of the wand against the stone and, again, began to chant. When she finished the end of all four wands looked like a tiny obelisk of green stone, a swirling streak of lighter stone within it.

As the wands lay on the table the swirls of lighter stone, barely moved, but when Harry picked up a wand, swirl on all four wands began to twist faster, and the light grew brighter.

"Whoa, that's wicked…" He whispered.

"Thought you might like that. Now, you can cast a minor glamour over them, if you're going to Hogwarts. No one will ever know." She laughed. "Alright, next?" Sirius laid his wands out and waited, with bated breath, to see what she would do with his. "Right, then… Ebony. Black Walnut. Poplar. And Bocote. Nice mix. Now, the cores. Dragon Heartstring. Lethifold blood. Unicorn Blood, willingly given. Nundu breath, liquified. Phoenix ash. Dragon Heartstring, again. Basilisk venom. And Snidget feather. Almost as bad as your friend's. Now, for a focus stone… hmm…Hematite… or Obsidian." She reached around the drawers and pulled out two. "Pick me five." She ordered and began to mould the wands into a staff and then back into four wands. When Sirius handed her two hematite stones and one large shard of obsidian, she sighed. "You would pick that one, wouldn't you?"

"Something wrong with my choices?" Sirius asked, frowning.

"Not wrong, it's just… that piece is going to demand blood. It's vampire obsidian not volcanic obsidian. Cut your hand and hold it out palm up." She waited for Sirius to do so, before dropping the stone onto his palm. "Now, we wait, it should only be a few moments, though." Sure enough, within a few seconds, the blood pooling on Sirius' palm was sucked into the stone and the wound healed. "Right, hand it over." She held out a gloved hand and Sirius dropped the stone into it, her other hand picking up the hematite.

Less than a minute later Sirius' wands had black obelisk ends with swirling silver highlights.

"All done, lads. Now, that vampire obsidian? You're going to have to feed it for the next few days. Once a day, should be enough. Same as here, cut your palm, which one doesn't matter, and let a wand-tip sit on the wound, because the wands are bonded, it'll share your blood across all four wands. Once it's absorbed enough, it will heal the wound and you'd never know it was there. When it's bonded with you completely, it won't take any more blood and you will have to heal the wound, the last time." She put her wand to her temple and drew out a strand of silvery-gold fluff and deposited it into a phial. "Just in case you need me do to something at some point in the future. Obliviates are fine, but a memory strand can be restored far easier."

"Thank you, Madam." Sirius and Harry both gave her bows.

"No worries, lads. Oh, do either of you have items bonded to your magical signature?" The old witch asked.

"I do." Harry was glad he'd broken the tranfiguration on the stuff Hermione had sent with him, but he was slightly concerned about his mokeskin pouch.

"If you like, I can blood bond it to you, it's much the same process as the wands." Came the offer.

"I appreciate it." Harry pulled out his pouch and placed it on the table. Madam Woodley picked it up with the rune-covered gloves and chanted over it, before gesturing to Harry. He cut his hand and she placed the pouch on his palm, a few seconds and the wound was healed.

"There you go, all done, young man." She smiled at him.

"Thank you." Harry held the pouch to his chest and smiled back at her.

"If you'll come with me, I'll see to the obliviate and your pay, Madam Woodley." Moody escorted the witch away.

"Wands all done?" Michael approached them.

"Apparently." Sirius answered.

"Great. Let's get back to it. Sarah? We're ready to activate the genetic overwrites." Michael called.

"Coming." Sarah left whatever it was that she was doing and joined them. "Okay. Ready?"

"Ready." Both Harry and Sirius nodded.

"Good." Michael nodded. "Now, this to going feel weird. Like a bubbling sensation, but all over your body. Let us know when it passes." He took a deep breath and in sync with Sarah began to chant.

The bubbling sensation was similar to having a fizzy drink and getting bubbles up your nose, but like Michael said, it was all over, and Harry was sure that even his hair was bubbling. He lifted a hand, fully expecting to see his skin bubbling, but was a little disappointed that it wasn't. What it was doing was changing colour, from the pale peaches and cream combination that Harry inherited from James and Lily, to a pale golden olive tone, that was far more common in the Black family.

When the bubbling passed, Harry and Sirius both nodded.

"Excellent. Now, let's get an impression of you both so we can do any changes you want." He cast an obscure charm and full-size images of Harry and Sirius appeared. "Now, let's double that and see what you'll look like as adults, huh?" A second cast and a second set of images appeared, a variant of the same charm was also cast, and the newer images began to age. "I think we can stop about there." Michael let his wand fall when the two older images looked to be about twenty-five. "So… changes?"

"Eyes. Back to blue-grey for me and green for Har- him." Sirius stumbled part way through Harry's name.

"Hey, don't worry about names, you'll have new names when we're finished, and Sarah and I will be obliviated of anything that happened after we entered the room." Michael shrugged. "It's standard for this type of situation. We came into the room, knowing it was going to happen."

"Right." Sirius sighed.

"Hair." Harry said. "Back to black but keep the new waviness." Harry liked it, it looked and felt softer and more manageable than the Potter mess he'd been dealt.

"Level out the adult heights, too, please." Sirius added. "Both of us, about five-ten."

"Build seems about right, I mean, we're both fairly slender. Maybe a little broader in the shoulders for me, to make us more even?" Harry turned to Sirius.

"Yeah, that'd be fine." Sirius nodded.

"Right. Like this?" Michael made some minute changes by chanting and pointing his wand at each of them and the images changed to show the long-term effects of those changes.

"Yeah…" Harry said.

"Yeah." Sirius agreed. "It's still us, our features are only fractionally changed, but with hair, build and colouring, it's obvious that we're siblings and our size makes it just as obvious that we're twins. Yeah, that's good."

"Great." Michael sighed. "So… all we have left are… names and the setting agent. We just need you to fill out magical birth certificates, do your Id tests to confirm and we're done. A setting agent and… Moody can handle the rest."

Sarah laid two magical birth certificates on the table and held out two quills. Harry looked at them and frowned.

"Let me guess… Blood quills…" he sighed.

"Yep. When a baby is born, the healers take a small sample of blood from the baby, that the parents use to link the magical birth certificate to the baby's core. As you're not babies, you get to do it yourselves and blood quills are the only implement that enable that link to be created."

"Great." Harry sighed but he picked up the quill and pulled a certificate towards him. "Now, I just need to make sure I spell it right."

"You chose it, pup." Sirius smirked.

"I did." Harry snorted, but continued to write. "But it sounds right, a good wizarding name, you know." He answered, glancing over to see Sirius put his quill down and rub the back of his hand.

"You still got those Identity test from Gringotts, lad?" Moody asked Harry.

"Yep. Here." He pulled out two bundles and laid them on the table.

"Well? You know what to do."

Harry smirked and flicked his wand, concentrating on a small cut. He let the crystal draw up his blood and fill, before dropping the darkened crystal into a phial and giving the phial a gentle shake, watching as Sirius did the same. Both he and Sirius pulled a sheet of parchment towards them and poured the liquid over the parchment.

"Should only take a few minutes." Harry said. "Gods, I hope this works."

"Me too, pup." Sirius nodded.

"You can't keep calling me 'pup', anymore Siri, you're the same age as me, now." Harry laughed.

"I'm still older than you. I can still call you 'pup' if I want." Sirius objected.

"Only by a few minutes."

"Still… older…" Sirius pouted.

Harry turned his Id test over and studied it.

Godfather – nil

Godmother - nil

"It worked." Harry, no, he was Titan, now. Titan's legs nearly collapsed under him, just in relief.

"Nice… Ty, I'm going to call you Ty." Sirius said.

"What about you? Is yours done?" Ha-Titan asked.

"Let's see." Sirius turned his test over

Paddrick Magellan Grimm. (1 April 1978 -)

Mother – Laura Anne Moody (30 June 1957 – 17 December 1978)

Father – Corvus Rigel Grimm (12 February 1954 – 17 December 1978)

Godfather – nil

Godmother - nil

"They both worked. It worked, Pads." Titan beamed at his new brother.

"Excellent. Now you get to take the setting agent and everything we've done today will be locked into your body and into your core." Michael smiled at them, as he held out two more phials.

Titan took the phial and swallowed the black liquid that smelt vaguely like cherries. He looked over and saw his brother doing the same thing.

"Gentlemen, there are no potions that can make the two of you closer, emotionally or mentally, however, viewing memories in a pensieve can help. If you have access to one, I would suggest using it. It will increase the familiarity you have with each other and it's that familiarity that will give people the impression of you having a twin-link connection." Sarah told them.

"I've access to one, I'll see that they use it." Moody grunted.

"It will help, trust me." Michael assured them all. "Been there, done that."

"Right, lads." Moody said. "You two take the portkey home, work on some trunks, if you want. I'll finish up here, dispose of the unused potions, get your papers backdated and lodged, do the obliviates and see about opening vaults for you."

"Yessir!" Both boys snapped Moody a salute and grabbed the old watchstrap that he held out.

As the portkey whisked them away, Titan heard Michael laugh.

"Those two are going to drive you even barmier than you already are, Moody."
