Bellatrix left the fortress as commanded by her new master, Xander. The orb she absorbed gave her power and healed all her ailments, but also gave her information about the second party of the contract.
Alexander Xander Harris, an orphanage matron loved the show Buffy the vampire slayer, so when the abandoned child was placed at the steps of the orphanage he was named after the happy go lucky guy in it.
Xander's orphanage was one of the good ones in Europe. This meant Xander had access to many resources, and the young genius used it.
He learned programing as a hobby which earned him a lot of money, but studied law and went to Harvard, where he died while finishing his doctorate because of his actions against a well-known real-estate company CEO.
Xander filed a lawsuit against the man for evicting people forcefully, from their homes. The CEO, seeing someone standing between him and his money, took the high road by having the sniper shoot Xander in the head.
That is where Xander was reborn as Harry and his story began as a reincarnated being who will travel to other worlds in the future.
This information was the price Xander had to pay for absolute loyalty. There were other options, but they would either corrupt the receiver or require a too high a price.
As Bellatrix was going through the information she received, a blue light flashed through the sky. A moment later she saw the bodies of the dementors falling to the ground, dead.
It is a well-known fact that you can't kill dementors, you can only repel them from you using the Patronus. Her new master is truly powerful, Bellatrix believed even more.
A few minutes later, she saw her master come out wearing what seems to be flexible armor. Following behind him were shadowy figures and dementors, no, they were different.
Her master walked forward and raised one of his arms
"ARISE" he bellowed
Bella felt a shiver go down her spine from the power exuding from the… man?... God? No KING.
Bella was taken of guard as from the bodies of the dementors came shadows. Bella watched wide eyed as the shadows all converged on her master and acted as if bowing.
"Sleep, I shall call upon you in the time of war" he spoke and the shadows vanished leaving only her and him there "come" he called to her with an extended hand
When she recovered from her shock, Bella found herself on the ground without realising it. She took a second but eventually she scurried to him and still on her newly scraped knees she took his hand and they vanished
---
The next moment Bella found herself in a place she couldn't recognise or see, she was confused until her master spoke "welcome to the Hanging Gardens"
That was when her vision focused and she can finally see where she was. The place was beautiful, but she had little to no time to look as her master started walking ahead with her only warning, him saying "follow"
She obeyed and followed. Soon enough they were met with two women. Her master greeted the warmly and then gestured to her "she will be a new maid of mine, please teach her the ropes Grayfia" Xander, no, Harry commanded "and make sure to fix whatever the orb didn't
"As you wish master" the maid, Grayfia bowed
Harry then turned to Bellatrix, retracting his helmet to reveal a handsome young man's face "we have an appointment tomorrow, for today call on Fiddy, he will be your assistant house elf" as if on call the house elf showed up "just remember, treat him with respect, or I'll be very upset" Harry warned and left Grayfia with her
Grayfia asked Bella to follow her and showed her to a large room with a bathroom attached. She then asked Bella to bathe before the medical examination.
Bella did as she was told. The medical examination showed that she was almost at hundred percent, just a bit malnourished.
As Bella rested in her new comfortable bed, fed and watered, she contemplated her new life. Grayfia briefed her on her duties, and honestly, it sounded too good to be true.
But she wasn't one to look at a gift horse in the mouth.

When Bella woke up the next morning she found the elf, Fiddy standing next to a chair with clothing on it "Master Harry Potter sir ask you dress and follow" the elf said and then popped towards the door and then popped again, out.
Bella wore the summer dress that was presented for her and walked out of the room. She found the elf waiting for her at the end of a hallway. Once she reached there the elf popped again and so on for about five minutes till she reached another building, where the elf gestured to it and disappeared.
Bella entered the large building and was met with Grayfia "Good morning" the maid greeted
"Good Morning" Bella replied through instinct as she was stunned by the causality of it
The maid then led Bella to a dining room, where there was the other woman, an old man and a young boy seated "Bella is here master" Grayfia spoke with a bow
"Stop doing that, we are in casual mode now" the boy complained "Bella" he called to her "have a seat, we're having breakfast"
Bella looked to Grayfia as if for permission, but when she saw the maid sitting, she followed suit "um, so m-m-master what do you need of me?" she asked
"The cup and your loyalty" the boy didn't even hesitate for a second "the cup that Voldi gave you is important for several reasons, but your loyalty is important for you. As long as you follow me, you will be my responsibility" Harry smiled gently at her
Throughout her life she was never loved or shown any kind of care. Her only value for her family was her marriageability, and so they sold her off to a man who would rather romp his own bloody brother.
It was why she liked Voldemort, he appreciated her for her talent, even if it was twisting her, she would rather be crazy but happy, rather than sane and unhappy.
Bella stopped her lamenting when a white owl swooped in and landed on Harry's shoulder "hey there lovely lady, do you have something for me?" Harry asked the proud snowy owl
With a prek and the bribery of several bacon strands the owl deposited her package and flew out, leaving the group amused.
"it looks like we're leaving to get the cup at noon today Bella" Harry informed the her with a smile
She could only nod but she gathered the courage and asked "won't we be in trouble if I just showed up there?"
Harry smiled and pulled out a strand of rope from the package "portkey into an inner office to activate at exactly noon" he then pulled a silver fabric "invisibility cloak for you to move around without being sighted" he spoke with a gentle smile that made her feel everything is going to be ok
---
Bella spent the time exploring the still mind boggling floating city. But soon enough noon came around and Harry and her are now standing in front of a gobbling "LongFang" Harry greeted
"Do I need to be worried?" the old goblin asked
"Not unless you attack me or her you don't" her master spoke in a low but threatening tone
"Fine" the goblin scowled "here to access the Lestrange vault I assume?"
Harry's pleasant demeanour returned "yes"
The Goblin took out a dagger and parchment "test" he spoke
---
Because Gringotts is sovereign land, it doesn't have to report a criminal when they come inside, nor does the ministry have authority inside Gringotts bank.
Because of this, her master was at the moment filling a trunk with all the books and artefacts in the vault while whatever gold in it was transferred to the black family vault.
She can do this because she is the last Lestrange alive, otherwise she can only access what her husband allowed, which wasn't much
Soon enough they were back in LongFang's office "thanks for this LongFang" Her master thanked the goblin
"Don't be a mopey idiot; with the amount of money you make me, I wouldn't be a goblin if I didn't give ya a little special treatment" the goblin replied with a toothy grin which her master returned
"One day I will have that tongue of yours LongFang" He said, still smiled
"Many have tried before you were even born child, I look forward to it" the goblin replied, his smile widening
That was the last thing said before the portkey activated. Once they reached the other end her master burst out laughing
"Oh I love that old bastard"
Bellatrix stood there not knowing what to do with this situation, but she knew one thing:
Her new master is… different
