Harry's Next Great Adventure in Sunnydale, Chapter 1

-Home Universe-

Harry was currently sitting in the overstuffed leather chair in his office. He was letting his powerful mind wander the vast amounts of different universes to see if any caught his fancy. Should such one capture his interest, he would head to that universe next to explore.

He heard his office door open and then close, followed by the sound of footsteps approaching him in his very comfortable chair. When Harry opened his eyes, he saw one of his many children walking toward him. Her name was Rose Hope Potter.

She's wearing black leather ankle boots and black low-cut skinny jeans that are so tight they look painted on her nubile body. She's wearing a short and tight white halter top exposing her midriff with the words Daddy's Lil Princess in red lettering. He could easily see Rose wasn't wearing any underwear or a bra. She didn't even need to wear a bra, seeing how her breasts were always perky and never sagged.

Rose is 18 years old, 5'4" tall, with a petite body that weighs 98 pounds. Her measurements are 33-23-33 with large C-cup breasts. She has an alabaster skin tone along with a blemish-free and clear complexion. Her facial features are a perfect mix of the best parts from her mothers, along with some from his own mother, Lily Potter, mixed in as well.

Lily Potter looked like a 21-year-old Scarlett Johansson, with bright red hair and emerald-green eyes.

Rose's hair ends about seven inches below the top of her shoulders, it is thick and slightly curly. Her hair is a bright and shimmering candy-apple red and has full-length bright silver streaks mixed in with it. Her eyes are a bright and vivid violet. She has a small button nose and naturally pouty heart-shaped rose-pink lips.

Rose is, in Harry's opinion, that he also keeps to himself, one of if not the most beautiful out of all his daughters. That also doesn't even take into account how she looks in her other form, which is even more amazingly beautiful in its own right.

Rose is unique in many ways, as she has his sense of adventure and his desire to explore other universes. Compared to his other children, who prefer to stay in the universe their mothers are from. Then there is also Rose's conception, which surprised even him with how it happened and how it all began.

As Harry locks his emerald-green eyes with Rose's eyes, he lets the memories come forward in his mind of how it all started while sharing them with her as well.

-Begin Flashback-

It was just another friend and family gathering in their primary home out of all the universes they had been to thus far. In the living room with Harry were his friends and many wives. He met all of them while exploring the many universes out there. They were talking about random things when Harry decided to bring something up.

"I need help with a new project of mine. Would one of my lovely wives like to assist me? You will mostly have free rein to do what you want while helping." Harry asked in a casual voice while looking around the room.

"What kind of project is it?" Asked Sam Carter, who was his wife from a Stargate universe.

"You know how when I first became an Ascended God, I absorbed the memories of some of my alternates and took over other versions of myself in the Harry Potter cluster?" Harry replied with a pleasant smile while admiring his blonde wife's beauty.

Clusters are a grouping of related universes that share a common theme or a key person. They were also known as a multiverse. In this case, Harry referred to the multiverse or cluster with all the universes that involve Harry Potter and the Wizarding World as its primary focus. There are some universes out there with a Harry Potter who is a wizard and is also a member of the Avengers or the Justice League. In that case, it would be a crossover universe of HP and either Marvel or DC.

"Yeah, why do you ask?" Buffy Summers said with a curious tone while the other people in the room were wondering the same thing she was.

"Well, I got to experience my original life as Harry Potter, with different events happening and the background origins changing things up for me. It made me want to experience the same thing again. But with the Buffy The Vampire Slayer cluster." Harry replied in a leading tone of voice.

"Why would you want to go back to Sunnydale and experience it again?" Faith asked in a tone that implied he was crazy.

Several of his wives were wondering why he was even asking for their help when he could easily handle it on his own.

'Maybe he wants some company there, or it could be something else. Hmm, if I did it. Then I could use the opportunity to fix a small problem I have.' Dawn thought to herself in the private part of her mind while looking at her husband.

Harry and all his wives are mind-linked, which allows them to see each other's memories and thoughts if they desire. However, they each have parts of their own minds that they can keep private thoughts and feelings to themselves. Granted, Harry, being who and what he is, could easily see those areas if he wanted to. But he never looks because he knows that doing so would greatly upset his wives. While he may be an Ascended God of Sex, he really hates sleeping on the couch, figuratively speaking.

"I will help you with the project, Harry. So what exactly do you need help with?" Dawn said while looking at the husband she shares with her sister wives.

"I want to set up a special Seed while also testing something I made recently." Harry said with a spark of amusement in his emerald-green eyes.

Seeds are what Harry calls the counterparts of himself that he sets up in a universe to see how things go, or he causes the Seed to merge with someone there. But neither of them is connected to him. This way, they aren't all he is, as an Ascended God, with all of his powers and access to the best technology. Nor are they fully aware of the true nature of all existence, including their own. For most of his Seeds, Harry mixes and matches some of his powers and abilities from his extended collection. He custom-builds the Seeds for what he wants to use in a particular universe to see how things go.

Dawn was about to reply to Harry, but the voice of her sister wife, Cordelia Chase, interrupted their conversation. Just as she usually does when Dawn is having a conversation with their shared husband. It is always annoying when Cordelia does this. Even more so at this particular moment, to the point that Dawn will make a few tweaks to punish her while helping Harry with his project.

"Going to another universe again sounds fun. But I don't want to go back to Sunnydale. How about we hit up this other universe instead? I found it from a TV show that I saw a while ago. They have a different type of vampires, werewolves, and magic users than Sunnydale had. The cluster is called The Vampire Diaries. You can join with one of your Seeds too." Cordelia spoke up, purposely taking Harry's attention away from Dawn and onto herself.

"Ohh, that sounds great, Cordy. Can I tag along? It's been a while since I got to kick some vampire ass." Faith said to Cordelia, also interrupting Dawn's conversation with Harry.

The brunette girl's left eye twitched in annoyance. So Dawn mentally tweaked her plans to punish Faith, too, for butting in on her conversation with Harry. Dawn opened her mouth to get back to the original topic. But again, she is interrupted by her older and, in her opinion, uglier sister wife.

"I was thinking that… " Cordelia started saying, which Dawn decided to ignore.

'Yep, I'm definitely going to be getting some revenge on them for this. It will be fun and sweet satisfaction to see both of their faces when they find out what happens.' Dawn thought to herself in a slightly vindictive mental voice in that private area of her mind.

"Let me deal with them quickly, and we can go somewhere quiet to hatch things out. Also, don't worry, because I'm going to have some fun with both of them in that TVD verse. To make up for them butting in while you were trying to help me. I will also link you in, so you can watch the results as it happens." Dawn heard Harry say to her in her mind, and she sent a mental hug and a kiss back to him in thanks.

Harry speaks up to get Cordelia and Faith's attention. He knows that Dawn hates it when her sister wives interrupt her or tries to cut in on something she wants to do alone with him.

"Cordelia, Faith." Harry says in a calm but commanding tone of voice. "I will get the both of you there. But I get to pick whether you are there as yourself or taking over someone else who is already in that universe. You will go with just Slayer powers and a sword that you can hide. But I will ensure you can keep up with the vampires there, strength and speed-wise, in that universe. Otherwise, you will not get to enjoy it if you just go in and God Mode it as they say. Also, I will put one of my Seeds there for you both to have fun with if you desire. I get to make a few tweaks if I want to, and you both will get to remember everything you know now, but I get to block certain memories or knowledge if I want to. Lastly, you won't remember any future knowledge you might have of what is to happen in that universe. I will drop you in that universe right before the events start in the first episode of that TV series." Harry told Cordelia and Faith to explain the conditions of his helping them with their own little adventure in a different universe.

Like Dawn, he has fun plans of his own, but they don't need to know that either. Harry was looking forward to getting his memories from the Seed he intends to plant in the TVD universe with Cordelia and Faith.

"Deal." Cordelia replied at the same time that Faith said. "Cool with me."

"Ok, we will hatch things out for that in a little while. But I'm going to get Dawn situated with my special project first. Also, no one is allowed to look into my next great adventure in Sunnydale until Dawn returns from it. I will even block myself from seeing into that universe, too. This way, no one can interfere with it." Harry said to Cordelia, Faith, and the room at large.

Harry had no idea that blocking the others out, even himself, was something that Dawn intended to ask him to do. But now she doesn't have to. There is less risk of them, or even Harry, finding out what her ultimate goal for helping him in all of this was.

Harry gets up and walks to where Dawn is sitting, then pulls her up and into his arms before teleporting them into his private little area where no one can see, hear, or get there. The only way to get there is for Harry to take them there himself. It was an area he made for himself if he wanted to get away for a bit or if some of his wives wanted some alone time with him without interruption. Then such a place is available.

"Thanks, Harry, you are the best.'' Dawn said before pulling him into a heated and passionate kiss.

"You're welcome, Dawn. But like with Cordelia and Faith, I have a few things I want to happen that are non-negotiable." Harry told the sexy 18-year-old girl in front of him with amusement in his voice and a prankster's glee shining in his eyes.

"Ok, that should be fine. What is it?" Dawn asked curiously, hoping it won't interfere with her primary goal.

"First is a special Seed of mine, which we can talk about later. But I should warn you that he will be off-limits to you to have sex with." Harry said with a gleam in his eyes.

"Ok, that's fine. There are plenty of girls in Sunnydale for me to have fun with. I also want you to make me a Seed of my own." Dawn said with a sweet smile on her face and saw her husband give her a nod in agreement.

"After doing some exploring of the whole of existence, I have seen other versions of vampires out there. It made me want to create a brand-new vampire breed just to see how they would work out, along with being a nod towards my divine domain. It is why I figured Sunnydale would be perfect for it, and it was also where our adventure had first started. You love, will be that vampire, the Vampire Queen, as some would say." Harry replied with a playful grin while his eyes lit up with delight.

"Tell me about this new vampire breed of yours, and will I be able to pick the time when I become one?" Dawn asked before adding. "Also, I can't wait to see Buffy's face when she finds out about her sister, The Vampire Queen." Dawn said with an amused voice before giggling.

Dawn planned to spend several years in the universe she is going to to achieve her goal. So she has plenty of time to adjust her plans if needed and really drag out Cordelia and Faith's punishment if she wants to.

"Yeah, you can pick when you become one. But I want it to happen at least three years before you leave that universe. This way, you have plenty of time to test it out thoroughly." Harry replied before kissing the blue-eyed girl lightly on the lips.

He was also looking forward to seeing Buffy's reaction to her sister being a vampire. Harry then started filling Dawn in on all the details and the ins and outs of this new vampire breed that he was going to make. While he was talking, the raven-haired god was lovingly caressing Dawn's bare arms and playing with her fingers.

"So, what do you think?" Harry asked once he finished explaining everything.

As Dawn sat in Harry's lap and listened to his plans and description of the new vampire breed, she was letting out a mental whoop of joy. Because of her plans, she could easily accommodate his request without it affecting her goal, given the time frame stipulation that he had added.

After Harry finished describing his new vampire breed and Dawn absorbed the information about them, she thought they sounded really cool. She was looking forward to her role as the Queen of this new vampire breed. She also started to mentally tweak her plans because she could use this new type of vampire to her advantage.

"Sounds like it will be fun and interesting. This new vampire breed sounds like they fit you perfectly as an Ascended God of Sex. They could be your priests, of sorts, who spread your divine gift." Dawn enthusiastically said because she was happy with how this had turned out so far. "Have you named this new breed of vampires yet?" The blue-eyed girl asked with a curious look on her face.

"I didn't mean to make them my priests, as you said. It's just how they ended up when I let my powers guide me into making the new breed." Harry replied with a slight shrug of his shoulders before adding. "As for the name of the new breed, I call them quasi-vampires. I won't ask what you will be doing there. You have free rein, just as long as you don't mess with my Seed too much. But tell me how you want your Seed set up and anything else that you might need." Harry said to Dawn before pulling her into a short kiss.

He was glad she had accepted it so willingly. Otherwise, he would have had to oversee this project himself. That would mess with what he wanted to happen to his special Seed, as he would be too tempted to interfere.

"So here is how I need my Seed set up…" Dawn said while she started filling Harry in on how she needed it designed.

Technically, Dawn doesn't need Harry's help in setting up her own Seed body. Because of all the things she can do as a Goddess and access to the technology available to her. But there are a few things she requires that only he can do to make this work just the way it needed to. Besides, it was nice when Harry took the time and did things for her.

"Also, I will need a custom puddle jumper capable of time and reality travel, so I can get things set up properly." Dawn added at the end.

A puddle jumper is a small and highly advanced spaceship made and used by the Alterans. It was designed for carrying things and is a short-range vessel. They didn't come with hyperdrives for faster than light travel, but the ones that Harry makes all have hyperdrive engines.

"No problem, Dawn. Let's get this show on the road!" Harry said with a grin on his face.

He was looking forward to absorbing this Seed's memories when Dawn returned from helping him with his project.
