Prologue

Harry was old and tired, but content with his life. At 260 years old he had experienced a lot in his life and was waiting to greet Death much like his ancestor Ignotus had. Over the years since Voldemort's final defeat, Harry's done a lot. He became an Auror for about a decade before retiring and learning about magic for the rest of his first century of life. He went through the effort of getting three masteries in Combat Magic, Charms, and Transfiguration. He even went through the process to become an Animagus and learn about the subjects he didn't take in Hogwarts.

However, things weren't easy. Only twenty years passed between Voldemort's final death and there being whispers of a new Dark Lord going around. Things escalated rapidly from there and soon the magical world was at war again, but on a much larger scale than Voldemort had ever managed to incite. Harry, having been the person who he was, had helped out in the fight. After another two decades passed, the wizarding nations finally banded together and put down this new Dark Lord, but at a high cost. The already low population of magical humans had dropped dramatically. Thanks to the war, Britain, France, and Italy were the only places that had a large enough population to be called magical nations left on the planet. It was widely recognized that wizards and other magical creatures and beings were dying.

The years passed and Harry grew older and wiser, researching magic and watching as what was left of the magical contingent in the world slowly die. His adopted children, for he had never married, all somehow managed to marry and have children of their own. However, it seems magic decided that the magicals had lasted long enough, and all of Harry's grandchildren and great grandchildren were without magic despite their obviously magical parents and grandparents. Harry was saddened by this, especially since his special instinct, which he had received from what he could only assume were the Deathly Hollows, told him that the world's end, both magical and mundane, was close.

Harry was surrounded by his remaining grandchildren and great grandchildren on his death bed. Only nine were there due to the rest dying before him from various causes. They were in a spacious room with the ceiling charmed to look like the sky, like Hogwarts' Great Hall. Harry had done this because he always felt at home in the sky and he never felt too comfortable under normal ceilings due to his childhood. This feeling of discomfort only grew when he achieved the Animagus transformation thanks to his form being that of a bird. As he had hoped, the sight of the sky and his remaining family would be the last thing he saw of this world alive. His breathing slowed until he sighed his last goodbye to his family and his chest stilled. They wept and said goodbye to him. Later in the week his family held a private funeral and burial, but what was left of the magicals all mourned the man when the news broke out.

When Harry was next aware, he was standing in a white train station that resembled King's Cross, a sight he never forgot no matter how long ago it's been since he last saw the place. The difference this time however was that it was empty except for Harry. Following a long-standing routine, which he's had since childhood when it came to waking up, he took stock of himself and noted that he looked and felt like he was in his twenty-year-old body and that the clothes he wore reflected what he usually wore during his twenties. After doing this, he idly observed the station as he waited to see if something would happen, since he didn't see any trains here, which was unlike last time. He didn't wait long however before something appeared within the station, though it was a ridiculously powerful something. In fact, it was so powerful he literally couldn't stand and so he fell to his hands and knees. Shaking his head, Harry straightened up as much as he could, still feeling like he had to stay on his knees for all that the power became less prominent, and looked up to where he felt the source of that power was.

In front of him several feet away was an androgynous figure cloaked in black and gray. That was where the logical description of features stopped. The only way to describe it in a way that fit the figure was that it was a dichotomy of constantly changing features and shifting heights. The figure felt powerful and old though, with power being visible in an undulating mist-like aura surrounding it. The feel of its power was unmistakable however and Harry felt an inexplicable rightness in being on his knees for this figure, for all that a part of his soul rebelled at that feeling. It did not help that a large portion of himself felt so uneasy about that rightness, his mind couldn't help being reminded of the effects of being under the Imperious Curse.

"I don't suppose you're Death, are you?" Harry asked not expecting an answer, going with the most logical thing he could figure out on what the figure could be while feeling drawn to it, given the circumstances. "I guess that there is a reason that you wanted me here and why I feel the need to kneel to you," he continued in an uneasy tone.

"Harold 'Harry' James Potter, chosen of the Hallows, I have been waiting for your proper arrival into my realm ever since you gained the cloak that I had gifted your ancestor. It is time for you to take your place as my Servant," was the reply in a voice that Harry could only think of as a legion speaking in perfect harmony, with an other-worldly echo-like quality to it. The words themselves left Harry shocked though, and holding back incredulous laughter when the thought of how Voldemort would have taken the information jumped into his head right then.

Harry, in the course of researching the Hollows, never thought that holding all three would make him Death's Master, or Servant for that matter. He wasn't arrogant or stupid enough to think that a mortal man or woman, or any mortal whatsoever, could be the master of something like Death. Especially with how small an amount that mortals understood about existence as a whole. However, he could easily see how people could assume that the Hallows would make them more than they did, what with how many things were lost from being passed down orally until reading became more prevalent, with information still being lost to time and translation. It was an entirely ridiculous notion that Harry threw out as a possibility almost immediately. He was kind of chafing at the thought of being an eternal servant though, but if all his years of life were good for something, it taught him to never assume.

"What exactly does it mean to be your servant, because I get the feeling that it isn't as straight forward as it sounds?" Harry questioned, both dreading and anticipating the answer.

"Your 'feeling' would be correct. As my Servant you will be sent to various worlds that are in need of having the Balance kept. You are the one that will be my physical enforcer in those worlds and it will be your job to make sure that living things die when they are supposed to, to stop tragedies like genocides and mass murders when they are not supposed to happen, and whatever else I need you to do. Since I am not cruel and I do know humans are social things, you will be capable of spending time with those you knew in your lives after you die and even talking to them while on the job so to speak, but you are incapable of staying with them permanently in the afterlife. When the End of all Things occurs however, well. That will be something we'll find out when it happens, together," Death explained as it made its way to stand in front of Harry's kneeling form, "There are powers that I will grant you, for each and every world you go to will require you to be born in a different body every time your soul enters them. While some abilities will be retained in worlds with similarities, you will in essence have a different set of abilities available each time you enter another world after finishing the mission in the previous world. The only things you'll be guaranteed to keep is your soul, all of the knowledge and memories you accumulate, and your bond to me. "

Death reached out and started to run a hand through Harry's hair, making Harry glare up in indignation and try to move away and finding he couldn't. His surprised face made Death laugh.

"You are my Servant Harry, as such you are mine to command, even if you haven't consciously recognized an action of mine to be a command. Your soul recognized it and you obeyed." Upon seeing Harry's horrified face Death took pity on him, "It won't be so bad Harry. I won't order you to do something that would make you end up a mindless and unfeeling creature due to being broken from an action I made you take. Harry, I chose you because of who you are as a person, it would be rather pointless of me to make you not that kind of person due to an action or actions I had you preform."

As Death was explaining this it continued to run its fingers through Harry's hair, slowly relaxing him and making him feel the urge to lean into the being in front of him. He really did not like that urge, nor why he had that urge, but he didn't say anything to the being that represented to the end of all things. Harry did have the distinct suspicion that the being knew anyway.

"Now, I will send you to the place where you can interact with you friends and family that died. It isn't properly the afterlife because you aren't capable of going there, but it is a place that I had made especially for my Servant for when I obtained one. It will be a place for you to relax, seeing as it is only minimally affected by the time the rest of existence is in. It also pulls the duty of pulling the old abilities you won't be able to use in the next worlds you visit out of you, storing them for when you do visit worlds that are compatible with said abilities. Relax and wait for my call Harry. There is no escaping this fate, so mull it over and hopefully you will find some peace with it." Death said.

With that, Harry's surroundings disappeared and the next thing he knew he was in front of a gathering of those he had cared about in a very comfortable looking place. Disoriented and feeling all sorts of things from the bombshell Death dropped on him, Harry didn't move towards them and just watched them interact with one another. It wasn't long before they all noticed him and rushed to greet him. With their welcomes and hugs, Harry soon relaxed. Perhaps he thought, it won't be so bad.

Harry was content, and relaxed, when Death summoned him for his mission. He had talked about what Death revealed about his new position with all of his former loved ones, and others he was surprised to see considering the animosity between him and them during life. The consensus that everyone had was that Harry had a good deal considering everything, and his mother did remind him that he would see and learn many things before coming back and telling them all about it between his missions as he recuperated. That, more than anything else, had him relax in regards to not being able to go on with them all, but he still was uneasy about the whole being unable to disobey Death's commands thing. He figured that as time wore on he would get used to it, so he just had to suck it up and march forward like the Gryffindor and war general he was.

The sight of a clearing in a totally white forest greeted him when he arrived wherever Death brought him to. The forest was as devoid of life as the King's Cross station replica was for all that it had the trees and undergrowth one would expect in a forest. It was actually very creepy if serene in its own way. Death stood in the middle of the clearing with Harry having appeared a foot away in front of the being. A minor flare of its power made Harry kneel and Death began to run its hand through his hair.

"I felt your relaxation and believe you to be ready for your first mission for me," the being said. Harry was still a little uneasy despite the time he had to accept things, but he listened to the being.

Death continued, "In the interest of making sure you are ready, I will explain what this world is like. You will be going to the world of Pokémon. The world was made from extremely powerful deities that were imbued with aspects of the Entities' powers. As I am an Entity myself, there is a pokémon with my aspect that is named Yveltal and is to be one of your connections to me." Death paused briefly and said, "Now, the problem with this world is that it will go through a series of world-shaking events that would have the potential to kill the world, with only one pure-hearted human child and his pokémon acting as the force to combat this. Something wants to disrupt this child's attempts to save the world though."

Pausing once more, Death gestured with a currently skeletal hand and an image appeared. The image was of a shadow-like being that was vaguely humanoid in shape. Death explained, "This is the thing that will influence the attempts at ending the world. It is an Armageddon Fiend. Its sole purpose is to end the world when the world is slated to die. The problem is that its sole purpose is to destroy things and make sure that they are destroyed. This means that it will constantly try to destroy the world before it is supposed to, so it must be suppressed until it is time for the world to end. It will also block attempts to save the world, no matter how futile depending on if it's the world's time to end or not, to make sure its purpose is completed. The deities of the world were successful in suppressing it until now." Looking at Harry, Death gave the impression that it wanted to know if he understood.

"So to get things straight, I'm being sent to make sure the…fiend…is suppressed so it doesn't prematurely destroy the world, help a kid make sure these events don't destroy the world, and make sure nothing else will stop this kid from preventing things from going to hell in a hand-basket. Anything else, like babysitting people to make sure they don't become mass murdering monsters?" He said, the last sentence in a sarcastic tone.

Death seemed amused at that, replying, "In fact, I do. There won't be many like that in this world, but it does happen. In fact, you will feel a pull that will guide you to one such person that will help you stay around the child hero. Now onto you getting into the world."

At that, Death had Harry stand and it shoved Harry through a portal that opened up behind him. Harry only had enough time to widen his eyes before the portal closed. Disconcerting laughter rang out in the clearing as Death thought about the surprises Harry would experience. It made a note to keep an eye on Harry, especially when the man learned what form he would take in that world.

A/N: So starts the first story. If Harry seems to be OOC, keep in mind that he was 260 years old when he died, with a majority of his family and friends dead before him. The next thing to keep in mind, what person is capable of arguing with Death when it has almost absolute control over its servant?
