HP: The Gacha Archmage

As I was jogging I thought of something I completely forgot about yesterday.

'Hey Sis can you show me the features of my World Traveler ability?'

[Sure thing Host. World Travel contains:

World Travel: Able to transfer oneself to a variety of worlds in the omniverse. May be changed at the host will. Able to choose Random, Variant, and General worlds. General Worlds stick the closest to cannon. Variant Worlds stray from cannon in one way or another. Random will send host to a random world. Host is allowed to choose some changes in the Variant world. Current Home World: Harry Potter Variant. Host may change Home World once he enters a new world

Currency Converter: Host is allowed to convert any currency to any other currency. Prices may vary.

Randomize: Just like a random world but with a difference. This ability allows one to choose a general world and host can appear at any time or place at random.

Time Manipulation: Host can choose the ratio of time passing between worlds. Currently set to 1 second in the Home World to 1 day in the other world. Can not go under one day in new worlds

Baby Mode: Host can choose to be reborn as a baby in the new world and awaken his memory at any moment host specifies]

Well isn't that interesting. That ROB certainly added a bit more than I asked for. Variant worlds would be like fanfiction worlds. The random worlds and randomize is to make things more interesting for me or ROB either way is fine. Currency Converter is definitely something good to have when going to new worlds as you can't do much with no money. Time manipulation is good as well. Baby mode though… I'll think about it. Maybe for DxD where I can get a sacred gear.

It was just a bit before lunch when I heard some taps on the window. Looking up I see a rather large eagle owl tapping on it. So I put down my book to get up and lift the window open, I take the owls letter and give it a few owl treats before opening said letter

"Dear Harry Potter,

It has come to my attention, via goblin, that you wish to correspond with me. Well consider this my correspondence. When you are alone call for my house elf Drippy and he will come and pick you up to bring you to me at my manor. I'll see if you are worthy of House Black. If your results are lacking I will personally kick you out but if you prove worthy you will stay with me until the school year starts.

Articus Black"

Well well well already setting up a meeting. He sure is eager to meet me even if it is just to decide I am worthy of House Blacks name.

I go out to find Ms Cole only to find her in her office which was the first place I looked. I open the door which makes Ms Cole look up at me "Hey Ms Cole"

"Harry, you look excited. Did something good happen?"

"Yes Ms Cole. I just received a letter by owl, like I told you about yesterday, the letter was from my great grandfather. He says I will be staying with him til school begins to get to know me better" because I am definitely going to prove worthy.

"That is very good news Harry! I knew you would find a family someday."

"Heh well he is sending his butler to get me a little bit away from the orphanage and he wants me there before Lunch so I should probably leave now. After packing my things" which is already done, everything I own is currently in my trunk besides the piano, which I am donating to the orphanage, and Hedwig.

"That's alright dear. Just stay safe and remember you always have a place to stay here. Now run along, you don't want to be late to meet your great grandfather" I nod and head to my dorm room grabbing a change of clothes into a mini versions of the suit Raizek wore in the series. After putting on my noble looking suit I finally grab my trunk and Hedwig before leaving. Once away and out of site of the orphanage and seeing no cars or people around I shrink my truck, putting it my pocket. Then I call out "Drippy!"

I see a small creature in a pillow case appear in front of me. It had long floppy ears, big black eyes, and a long nose that dipped at the end. "Young Master be ready to meet Master Black?" Okay it's official house elves are kinda adorable and fugly at the same time.

"Yes Drippy take me to Lord Black please" I held out my hand to the creature when it grabs my hand and we pop up in what looks like a gothic Victorian tea room. That's where I first saw him, Articus Black. He had hair as black as night, a small mustache and beard, sharp black eyes, and he was dressed in a set of regal looking robes that brought a sense of nobleness. He was currently sitting down at a small table that had tea, fruit and cheese along with a small plate of pastries.

"Greetings Lord Black, I'm Harry Potter"

"I know who you are boy." He says as he eyes me over with a judgmental look "Well hurry up and take a seat" I steadily walk to the chair putting on my most noble stature to show I know how to walk the walk.

"Well, Harry Potter. The Boy Who Lived, don't think your title will make a difference in how I judge you."

"Yes Lord Black." I say elegantly.

"Well at least you can walk like a Pure Blood but let's see if you can talk like one. But no more of calling me Lord Black. You may call me grandfather, for now."

"Yes Grandfather" I give a tiny bit of a smile as I see this as a good sign so far.

I nods slightly. "Now imagine my surprise when a Gringotts owl delivered me a letter saying that Harry Potter wanted to talk with me. That my grandson Sirius had adopted you an entire year before that Halloween night when he was dubbed a traitor"

"I don't think he was a traitor grandfather"

"Of course he wasn't! Sirius may have no love for his family. Merlin knows I regret having let my son marry Walburga. But he loved James like a brother. The simple fact he adopted you is proof enough he would never betray the Potters. But people do not listen to my words as they once did so I have been unable to prove he wasn't one"

"Actually I may have a way to get proof, not that it is needed to free Sirius though."

He mildly glares at me "What do you mean boy?"

"Well I was studying the laws and customs of this world and one section mentions that a Pure Blood can only be held in detention for 30 days pending a trial. But from what I know is he was sent to Azkaban without a trial. So technically Sirius is free to leave whenever he wants. In fact I bet Sirius, overwhelmed by grief, didn't speak up to anyone during his arrest either."

He stops glaring at me and leans back with a calculating look in his eyes.

"In fact Grandfather can use that as leverage"

"How do you propose I do this?"

"Well you are a respected Pure Blood in their circles, even though some people don't trust the Blacks anymore, so you can go to Amelia Bones and demand the release of Sirius using what I stated as law. If that fails then demand for him to have a proper trial that he never got by declaring a miscarriage of justice in the DMLE. The fact that most other Death Eaters got a trial but Pure Blood Sirius Black didn't sets a bad example to other Pure Bloods. If he can be sent to Azkaban without a trial then who else could be sent to it. Just use that and you will get people moving. I planned to get a lawyer for this myself but I don't think it is needed for me anymore right grandfather"

"… That is quite a cunning plan you have. You planned this yourself just by reading Wizard Laws just yesterday?" I nod my head and he smiles a bit, well more like a smirk "Well looks like you have some Slytherin cunning in you"

"Well I have more than that in me. My full title could be said to be Harry James Potter-Black-Slytherin"

"What?! How can you be a Slytherin?" This is the first time I see him lose his demeanor "The only descendants he had was the Gaunts"

"Well according to the goblins my mother was the first true Slytherin in centuries that awoke magic making her the Heir. The Gaunts however were just a branch family of the true family. Just don't ask me how it came to be that the Slytherins produced squibs until only the Gaunts had magic. I hope to find the Chamber of Secrets and inside hope I can find some of Salazars notes"

"… I see." He seems to be lost in thought for a few moments before finally acknowledging me "You still have much to learn about being a Pure Blood. I will teach you and make you the Heir of House Black if you manage to please me with your training"

"Wait, isn't Sirius the Heir?"

He sighs "Truthfully Harry I doubt Sirius, after spending near a decade in Azkaban, will be stable enough to lead House Black. It would be a miracle if he didn't go insane from the Dementors."

"Then I will accept your offer of training. When do we begin?"

"Right now"
