Obscurus, in his Fox form, patrolled the Campsite, checking his wards around the campground and the artifact tent. So far the treasure hunters only came close enough to look at his wards, not yet attempting to try to break through them. The night was warm and Harry enjoyed the quiet that fell over the snoozing camp as he thought about the past week.

Bill Weasley was the one to pick him up at the International Portkey room, greatly amusing Harry when Bill seemed unsure whether Harry was being truthful about his identity as Obscurus or not. A day later, Harry got a message from the Prince account manager with thanks from both the manager and the new Lord Prince. He also got a call from Sirius later that day and the two talked for an hour before Harry had to do a midday patrol. Sure he had alarms for when someone even attempted to try to break through the wards but he still made sure to patrol around every mealtime and once more in the middle of the night. He slept around his nightly patrol with a nap after his midday patrol if he didn't feel like he got enough sleep.

Unfortunately, his wandering around during the daytime patrols in his human form took the notice of one Molly Weasley, who decided to unofficially adopt him again. Every time she went and mothered him, which he always tried to keep the disgruntled look off his face, he could see Bill shaking with concealed laughter. Harry always managed to glare at the Curse Breaker, except for one memorable dinner.

Molly had just finished filling Harry's plate for the third time, much to Bill's amusement. Harry looked around the table and took note of where everyone was sitting before smirking at Bill. Bill gave him a wary look, the twins noticed the silent exchange and kept a close eye on the new boy to see what was going on. Bill, Fred, George, Percy, and Arthur sat at one side of the table with Charlie in front of Bill followed by Harry, Ron, Ginny, and Molly. Harry waited until Charlie was in the middle of drinking his pumpkin juice before leaning over to whisper in his ear without Ron hearing him.

"Sooner or later you're mother is going to realize I'm the assassin that the goblins," Harry whispered. Charlie inhaled his juice wrong before spraying it all over Bill, making the twins jump back at the wet projectiles. Harry smirked at a yet Bill before going back to eating his food while Charlie coughed to clear his airways. The twins started laughing while Molly got back up and went to help her second oldest. Bill used his napkin to dry himself off while he glared at Harry.

"You have got to be kidding me!" Charlie shouted, turning to stare at Harry.

"I'm deadly serious," Harry answered.

"What's going on?" Ginny demanded.

"Obscurus just told me he's the assassin that the goblins sent to protect the camp," Charlie answered. Everyone except Bill turned to stare at Harry, who didn't acknowledge them and continued to eat.

"Don't be ridiculous, Charlie," Molly scolded.

"Mom," Bill called, getting her attention. "It's true. Obscurus is actually the assassin assigned to the camp."

"He's just a child," Molly tried to counter.

"Mrs. Weasley, I stopped being a child the day my aunt and uncle decided I would be the equivalent to a House elf when I was four. I took my OWLs and NEWTs when I was 12 when it became apparent that school held too many strings attached. Out of the 15 subjects I tested in, I got straight O's in both my OWLs and NEWTs. I have spent the last six months apprenticing under Master Erluk of the ABHD in Gringotts. In fact, I had just finished my first assignment just a day before getting assigned here."

Harry mentally cackled at their stunned looks. Even Ron was stunned enough to stop eating and stare at him. At least they're staring at him for something he did instead of surviving when his own parents didn't.

"And what do your parents have to say about you going off to kill people?!" Molly screeched, getting over her shock first.

"I wouldn't know," Harry answered, his voice turning monotone. "They died when I was a baby and my relatives hate magic enough that when I gave them the option to get rid of me for good, they immediately took it." An awkward silence fell over the table as Harry wiped his mouth, only finishing half of what was on his third plate. "Thank you for the meal, Mrs. Weasley, but I must get to patrol." Harry then waved at Bill and walked away to patrol.

That had been three days ago and now Molly insisted he joins them at every meal to get to know him, although he kept certain facts vague with the excuse that he doesn't want anyone to recognize his true Identity. It's more for his privacy and his goblin friends than anything else, but still, it was nice to have his surrogate mother again.

Harry stopped when he noticed movement nearby and crouched low to keep hidden. If his Fox form could smirk, it would be. For a little farther ahead, a certain rat decided to have a midnight stroll. It was easy for Harry to sneak up on him and catch him in his mouth before darting to his own tent. Harry shoved him into the cage he had set out earlier before shifting into his human form and locking the cage before he could escape. He then moved the cage to the table and gave the rat a feral grin.

"Hello, Peter Pettigrew," Harry greeted. "You're going to pay for setting up my godfather." Harry then took out his mirror and took a selfie with the rat and sent it to Ragnok, Griphook, Erluk, and Sirius before returning to his patrol.

The next morning, Harry joined the Weasleys for breakfast again and heard Ron whine about his missing rat between bites of food. Harry winced when food kept spraying out of the 13-year-old's mouth.

"I saw him over near the artifact tent during my patrol last night," Harry said. "You might want to try over there, but he might have already moved on to a different location."

"Thanks, mate," Ron said, his mouth full of eggs.

Harry just nodded with a grimace before going to grab his water. Harry noticed Fred and George subtly watching him and decided to have a little more fun. So he smirked at them, making them instantly go wary, before bringing his cup to his mouth, but not drinking it. He also noticed Bill, Charlie, and Percy all took notice of his smirk to the twins and decided to watch what Harry would do to them. Harry pulled the cup away from his mouth and turned to Ron.

"Hey, Ron. Can you try this, please? I think it tastes a little funny," Harry asked, sounding innocent. Harry giggled when the twins' eyes widened, realizing what Harry was doing.

"Sure," Ron answered, taking a large swig. A second later, Ron grew a beak and patchy feathers of various colors. Harry hummed in thought as Ron began to freak out. It only took a moment to realize that this was the beginning stages of the Twins' Canary Creams.

"You two might have better luck making it consistent if you made them into biscuits," Harry suggested as Molly started to fuss with Ron. "Maybe something similar to custard creams." The older Weasley boys stared at Harry in shock.

"Did… did you just help the twins make their prank better ?" Percy asked, wary of Harry.

"Hm? Oh, yes," Harry answered. "My father and his friends were pranksters, even had their own codenames and Group name." Percy's horror grew as he thought about all the new products Harry could help the twins with.

"Really?" The twins asked.

"Yep, they went by The Marauders. My dad was Prongs and my godfather was Padfoot. I think, if I remember hearing right, Moony might be teaching defense at Hogwarts this year." That reminded him, he needed to get Moony tested at Gringotts. Neville too.

Harry was quickly brought out of his thoughts by loud gasps from the twins. Then he remembered who he got the Marauder's Map from in his first lifetime. He mentally groaned, realizing he might have just made the twins into his groupies. Fred and George suddenly frowned, in thought.

"What happened to Wormtail?" Fred and George asked at the same time.

"Wormtail was a Death Eater and traitor," Harry sneered a sneer that would have made Snape proud. "It's because of that sniveling coward that my parents are dead." The twins and older Weasleys winced at Harry's harsh tone. He then shook himself out of thoughts of the rat before being distracted by his pocket vibrating. With a quick glance at his mirror, he saw they were excited replies from his goblin friends and godfather. Harry then turned to the twins with a smile. "You should know that all four of them were Gryffindors and three of the four were animagi. I can see if Padfoot will pass on their pranks." Harry then got up and said his goodbyes before going on patrol again. He intended to get his patrol out of the way so he could meet up with the Weasley family for final goodbyes before they left for England. He also made sure to slip the twins his Animagus book with all his notes in it for them to try while he was saying goodbye to them.

Line Break

Harry stared at the dead bodies in front of him and winced, accepting he went a little overpowered with his severing charms. With a sigh, Harry pulled all of the loose limbs and torsos from the three different bodies into a pile with his magic before pulling a note out of his pocket. He was about to stick the note on the top torso when a gasping curse caught his attention. Still on high alert, Harry quickly pinned the intruder into the sand with his before looking at the person and wincing.

"Sorry Bill," Harry said, releasing the Curse Breaker from his magic.

"It's alright," Bill answered, getting up. The eldest Weasley brother stared at the pile of limbs. "You know, it's one thing knowing about you being an assassin, it's another seeing you in action." Harry winced a little.

"I went a little overpowered with my severing charm," Harry explained. "They were going to die anyway, but I didn't mean to be so…"

"Serial Killer-ish?"

"Close enough." The two chuckled before Harry used his magic to send the deceased back to their own camp. He then used a strong scourgify to get rid of all the blood left over.

"Where did you send them?" Bill asked.

"I found the treasure hunters' camp a few days ago," Harry answered. "So I sent them there as a warning to the rest of their group."

"Was that the day Mum scolded you for missing lunch?" Bill asked, amused at Harry's grimace.

"Unfortunately." Bill chuckled at his reply. "What are you doing up so late anyway?"

"I heard the fighting and wanted to make sure everything was okay," Bill answered. "By the time I came around the tent, you were finishing up." Harry nodded in acknowledgment before walking Bill to his tent and heading to his own afterward. It wasn't until a week later that the treasure hunters made another attempt at the artifact tent, which Bill watched in fascination.

"I'm going to head to their camp to make sure we aren't going to have another wave," Harry told Bill.

"Alright, I'll let the team know if you aren't back by dawn," Bill told him. Harry smiled and nodded to him before apparating away with the dozen bodies. Harry returned half an hour later to tell him that there wasn't another wave coming. Harry then cleaned up the blood again before they both went to bed. As Harry fell asleep, he had to wonder why they kept attacking at night.
