Harry and the Botched Cult Ritual.

AN: just a short one, I've had people asking me who Harry got bound to (I won't say summoned, because technically the cultists summoned em), so here they are in plain text. Lancer = Medusa (young), Rider = Medusa(fate stay night version, aka adult), and Avenger = Gorgon, aka the monstrous version that is similar to the legend. All three can be found in the Fate/Grand Order Wiki if you need pictures.

AN2: a lot of narration at the start, but do we really want to get bogged down in bureaucracy?

IMPORTANT AN: Going by the description in the grand order wiki, which had all her conversations and bond level info, Gorgon has an inhuman mentality and moral code. Which means that I'll have her take actions that the other Medusas' would balk at, or humans would.

Chapter 2: Settling accounts

The next few weeks had Rider out of the house almost constantly, leaving Harry with Lancer, and Avenger.

Rider was working towards getting custody of Harry in the muggle world, working with the insurance company to get the insurance money from the deaths of Vernon and Petunia, since Harry was living with them at the time and he was the only survivor, getting the banks to turn the money from the accounts of the three Dursleys over to Harry, again as the sole survivor of the household, and attempting to find a new place to live, or she would've if Harry hadn't said that he had no problems staying there. This meant they needed to find the deed, and get it turned over to the sole surviving family member.

The fact that the cult was now dead, made the police have very little to do in their investigation, they did a quick sweep through the house, the day after the event, taking fingerprints from everybody, but that was pretty pointless as the cultist outfits included gloves, partial masks, and very sharp knives.

The fact that they had literally dozens of houses to go through, along with the warehouse where the cult performed their bloody task, made them glad to be able to just do a quick look through one so as not to trouble a child or his rescuers.

Harry's Aunt Marge had been visiting when they had been attacked.

Harry's memory of Ripper the dog being killed for attacking a man with a gun gave him warm and fuzzy feelings.

These events were compounded by the visits from the police, social services, reporters, nosy relatives of now dead neighbors, and some weird men in red robes.

The police were surprisingly cooperative with the purple haired woman, she later found out that it was because she had 'risked' her life to save the sole survivor of the ritual. She kept quiet about the fact that her fellow servants and herself were in more danger from the boy then they were from the cult.

After all the boy could command them to do anything.

On the home front while Rider was exhausting herself trying to get everything set up, Lancer was astralizing and sneaking into the homes of the dead to search for cash, as until Rider was finished they needed money for food, furniture, and clothes as all three servants had taken one look at the boy's wardrobe, and deemed it unsuitable.

Lancer managed to collect nearly ten thousand in cash from the two or three dozen empty houses left by the cult.

This could have been bad, as that left Harry with... Avenger.

This could've been bad because of her alignment, and the fact that Avenger had a nonhuman outlook, and would have no guilt in killing anything that annoyed her, including her master.

This did not occur to Lancer until she had walked in after her first scavenging mission.

She smelt blood, fresh blood, and rushed into the living room, only to find a bloody white skull mask on the floor, a wand under the coffee table, and a bloody Avenger lying on the couch watching TV being the only indications of a minor struggle.

Harry was lying on her with a wing being used for a blanket much to Lancer's shock and amusement.

The smirk Avenger sent lancer indicated that she knew exactly what the other had been thinking, and with a gentle clawed hand rubbed the sleeping boy's head, indicating that the boy was safe with her.

Lancer discussed the issue with Rider the next day, but neither had a better idea of who to take care of him while they performed their tasks.

Or rather who else they would've trusted enough to do so.

They did wonder who attacked the two though.

Flashback!

Half an hour before a blonde man was chuckling. His cousin in the ministry, who had just been fired the day before for giving out the wrong forms, had discovered Harry Potter's location from the engagement paperwork.

The boy was living in a muggle home without a single protection, beyond some owl wards, which made him an easy target. There was something in there with him, but that was irrelevant. They would both die, as they couldn't stand against a pureblood like himself.

The fact that the other two that he saw hanging around, the child, and the adult, both with purple hair, were out of the house as well simply made it easier. He would kill them as they came home.

Sneaking into the house he saw the monster woman and boy eyeing each other warily. He pointed the wand at the, to him, marginally more dangerous foe, the half-blood, and started "Avad... ERK" the woman moved, and before he could hit the third syllable of the spell she had his wand arm in one hand, and his throat in another.

She then squeezed the arm that held his hard enough to splinter his bones and make him drop his wand.

Turning toward the young boy she said, "Master, I'll take care of this trash."

She ripped the man's mask off, with her claws spilling some of the man's blood on the mask, and dropped it on the ground. Mindful more of the fact that the mess would be harder to clean up inside, she dragged the man out back by his neck, and since the police were on the other side of the street at that point, she tore him apart with her snakeheads, and had them devour the man to get rid of the body.

Fewer questions that way.

Entering the living room again she saw the boy staring at her wide-eyed. She then noted that she was covered in blood and sighed. So much for... huh?

The boy managed to find the least gore splotched part of her and latched his skinny arms around her waist. She smiled at the boy, she was definitely happier with the engagement now, where she was apathetic before, as seeing her gore splattered figure didn't scare him off than this might actually work.

She, of course, didn't realize that someone obviously trying to attack him, and her saving him, makes a major impression, especially since he didn't really figure it was part of her nature.

The vibe he had from her from the start was actually similar to the saner members of the cult. Cold, heartless, and uncaring of anyone but herself.

The fact that she, without hesitation saved him proved him wrong.

He would later find that he was partially right. Avenger has 'kindness', 'Love', and 'compassion' but they weren't the primary part of her nature. She doesn't really show them most of the time the way others would, she shows it in her own way.

To those, she cares about at least. The others? She would kill if they got in her way without pity or remorse. The problem is that usually, it was hard to get into the category of 'cares about' without getting killed.

The boy managed, with one action, to do just that. Hugging a monster like her, covered in a man's blood, without fear or hesitation... beyond finding the least blood splattered part of her.

With a slight smile, she picked up the boy and laid down on the ruined couch with him, to see what was on the miraculously undamaged TV.

He fell asleep quickly as her wing covered him, as he was still tired from the night before.

It was at this point Lancer came in.

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.

Flashback end.

Lancer, still not knowing the situation, sighed and simply said, "Could you clean yourself up after you do these things from now on? At least so we don't have bloodstained furniture. Now, what happened?"

Upon hearing the explanation, she simply nodded, and said, "Good job, and good thinking keeping Harry from seeing you tear that person apart."

Unknown to both servants Harry had woken up and heard everything.

He simply didn't care, the man intended to kill him, by the tone of his voice when he spoke, and probably Avenger, he got what he deserved. How he got the stick to start glowing green was strange though.

He simply snuggled further into Avengers feathery embrace.

"Actually I didn't, I Just didn't want to clean up the mess," avenger admitted without shame.

Lancer facepalmed, and wished Rider was there to help.

Dinner that night was Greek and cooked by Rider.

It was mediocre, as while she knew how to use the oven as part of the information granted by the summoning, she had never actually done so, and she refused to allow a ten-year-old to do so.

Avenger was still full from earlier.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.

Another month passed, and Harry was in Diagon Alley. He had received a letter inviting him to a magic school, that his servants assured him was genuine.

So he was here to borrow an owl so that he could send his reply.

The past month had been hectic. Medusa finally got the funds released, and the house had been renovated, and furniture replaced. There were only three beds at present, as Harry kept sleeping with Avenger, so they had just bought a huge bed for the master bedroom, in fact the bed took up almost the whole space, as they fully expected to all end up in the same bed as Harry when he was old enough for the contract to force the marriage. (EN)

She drove the two with her new motorcycle, and sidecar, with Harry riding behind her, and Lancer in the sidecar.

The street was still mostly empty, despite the real estate companies giving steep discounts on what was formerly prime real estate. The shadow of the tragedy made most people not want to move there. So far there was only one man who did so, a shaggy man who sunk his entire savings into a home he was currently employed by the companies managing the area to keep the lawns and homes in good condition. He had seen the boy who was part of the only other household, and at first thought, he was the son of his dead friends but shook off the idea as impossible.

It was also discovered that while Avenger hates cooked meals, she was the best cook of the servants. She was also the closest to Harry on a personal level, but that was primarily because not only did she save him, but she spent the most time with him over the last two months.

Both Rider and Lancer accompanied Harry to the alley so that they could spend some time with their young master.

The three of them agreed that after visiting the bank, and seeing whether Harry had an account there, that they would each send a few hours alone with their betrothed.

The trip to the bank was uneventful, as was the wait in line, and the request for an inheritance ritual.

It was then that all hell broke loose.

The ritual was simple, all Harry needed to do was fill an egg cup sized hole in a rune-covered small stone with blood, and the runes would activate, causing the stone to change shape, and end up as a paper-thin stone with all the inheritances listed.

The fact that the goblins found out that he was Harry Potter, had him dragged to the goblin kings in chains, as well as the two females with him. They could easily escape by going into their astral form, but they wanted to know what the problem was, if necessary, they would butcher their way out.

"How dare you enter our bank after the insults you gave us Mr. Potter!" the goblin king roared.

"What insult?" Rider asked cautiously.

"He knows very well what the insult is, we have been sending letters asking for a meeting for the last two months rewarding the changes to his accounts because of his engagements. But he hasn't replied."

Lancer spoke up angrily, "he hasn't had any letters from you, in fact, the first owl he obtained was his school list."

Ragnok the goblin king's anger stalled, and he turned towards the girl that had spoken to him, then the boy, and then snarled "Is that true?" at the boy's frantic nodding the king stalked back to his throne. Sitting down heavily he thought for a second and noted that the girls looked ready to do something. What they could do he didn't know, but he didn't want to take chances.

"You claim that you had no correspondence from us, at all?" the goblin asked, after activating a truthward, which would tell him if they were lying to him, focused on the boy.

"No, I didn't even know you were real until today," Harry replied.

"Release them. My apologies, I thought you were deliberately snubbing us. I will have to talk to your magical guardian about this," the kind ordered.

"I have had nothing to do with the missing letters," Rider replied. "Perhaps whoever was his guardian before me did so."

The goblin ordered chairs to be brought in for his guests, and the boy's file to be brought before him.

What he saw made him see red. The boy's trust vault had been illegally emptied by Albus Dumbledore, and placed into the man's personal account. The man hadn't even been the boy's magical guardian for over eight years. Magical guardians needed to live with their charge, the exception, of course, being the headmaster of a muggleborn's magical school, as the headmaster couldn't live with hundreds of children in different households, or a ward of the state. The exceptions were irrelevant anyway, as Dumbledore had assumed personal guardianship of the boy.

In short, the man had no cause to take the money, especially since the money was earmarked for the boy's care. The false engagement contract that was in the file was even more damning, as a magical guardian, that isn't the head of a family, can't make such contracts.

"I see, I will replace the keys to both your family Vault and your trust vault. The cost of which, along with the inheritance ritual shall come out of the vault belonging to someone who stole money from you, after the money, interest, and fees have been taken out," the goblin king said with a smirk. "And as an apology for your treatment today, we will have our best senior account manager replace the one that allowed the thefts to occur. Now I assume that you need to withdraw funds, let's see." the goblin king thought for a second than smirked, one of his guards had been getting annoying lately. "Goreaxe, take these three to see their new key getting forged, then Mr. Potter's vaults."

The named goblin looked like he was going to object, but at his king's glare, he decided not to. Perhaps putting laxatives in his king's grog, for the fifth time that week, had been a bad idea.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.

After the group left he called in both the current, and future account managers. He knew the new manager would be raking in the money from all of the unlicensed and unauthorized Harry Potter merchandise.

The next few years would be very profitable for both the boy and the nation.

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.

They arrived at the forges just in time to see the new key being cooled and was soon back on the surface with a bag full of coins.

Then Harry took off with Lancer while Rider started the school shopping.

The robe shop was empty of customers at the time he arrived, so he was able to get measured in under half an hour.

The two drifted in and out f stored, and were absolutely disgusted at the Harry Potter merchandise, and especially the 'completely lifelike' Harry Potter sex dolls... supposedly of him at every age until his current one.

They ended up at an ice-cream shop for the end of their tie, while they waited for Rider. The servant arrived with the trunk and the vast majority of the items he needed, just in time to take over.

They did much the same, they picked up his robes, and then stopped at the wand shop.

Rider nearly gutted the man for sneaking up on them.

"Mr. Potter, and someone whom I don't know, you have come for your wand correct? Let's see."

The next two hours were taken up by Harry trying every single wand in the store, a process that left the shop in a complete mess, barely standing, and the wandmaker a female teen-aged cross between human and platypus.

She was very annoyed at that, and decided to destroy the holly and phoenix feather wand that changed him, now her.

"It looks like none of my wands match you. Which means I will need to custom craft you a wand, most unusual. You seem to react best to oak, and a full foot long, but the core escapes me." Ollivander said.

"I have an idea, my family had found some hairs and scales that might work for him," Rider replied.

"Let me see," the platypus girl replied then cast a few spells at the materials, and Harry. "Hmm, yes, these will work, in fact, they seem to have been donated for him, willingly, I hope you don't mind if I keep the remainder? I'll knock fifty percent of the price of my custom job for it."

"Agreed," Rider replied,

"Fifty Galleons is the normal price, so it will be twenty-five, and it'll take a week, is this okay?"

"Yes," an annoyed Harry said as he was sick and tired of being in the shop.

Rider promised a better time the next time they went out, as they collected Lancer, and headed home.

None of them remembered to send a letter, the contents of which would change after Rider read a book that night.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.

The next day, two letters arrived at the Potter, formerly Dursley, household.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.
