Author notes:

Hey guys, this is my first fanfic and I really wanted to make this idea, so I tried it out. Be gentle with me.

READ THE WARNINGS.

Warnings: The special things people should read before taking action.

This is my first fic and I've learned that I have to repeatedly post warnings in hopes of deterring certain types of readers. So, here you go:

-This is a GARY STU multiverse fic! BEWARE that this is a Gary sue fic for anyone who can't stand this type you have been warned.

-FOR THE LOVE OF FU*KING… Please google 'FANFICTION DEFINITION' before you read ANY fanfiction.

-This is a slight crackfic. NO, I do not care about CANON. YES, I understand CANON in the worlds I use. I ALSO wikia shit for extra info. If I choose to do so, I WILL change CANON for my own pleasure. AU characters and new world stuff. You have been warned.

-To all you mythology fans, this is a fanfic and I've changed up how some of the gods work so yeah, not massive changes but if anyone cares then you have been warned. I don't care what is canon mythology or not. My fic, my rules.

-This fic will start with the Harry Potter world and carry on into the Danmachi world. I'm not sure If I'll make it farther then that but we will see how it goes for now. I only have plans for these two worlds at the moment. You have been warned.

-The Harry Potter generation of wizards and witches will NOT be important to my fic.

- This will be a HAREM fic but not an insane one. One woman from the Harry Potter world plus two crossover women from another world and anywhere from one to three in Danmachi. I refuse to have more than 6 women since it will get way to complicated. You have been warned.

-When dialogue is not clear about who is speaking, I will try to list it. When I literally imply who is speaking then it shouldn't be hard to figure it out. You have been warned.

-Not everything will make sense. It doesn't have to. This is fanfiction. Don't try to use logic on my bullshit.

-For the release rate, I'll do my best but no promises. Sometimes I can release multiple times a week and others once in ten days. You have been warned.

Honestly, I ask of you guys to read the above warning before you do a review about it. It would be very appreciated, and no one will look stupid. Now let's begin the novel!

Please read the warnings. Seriously, it's getting exhausting to hear complaints that were already stated.

Disclaimer: I do not own harry potter, solo leveling, overlord, or danmachi.

Prologue

"Well, it was a fun life."

Looking around at the beautiful scenery before me, I can't help but smile, it looked as if it would seem in a storybook. The sights, the sounds, the smells, and the tastes were out of the world. The sky, filled with pockets of white clouds stretching for miles.

The lush green landscape, the warmth of the sunlight, everything seemed so coherent. You could hear the chorus of the pleasant-sounding birds. The trees looked like silhouettes in the glorious expanse.

I could smell the scent of the forest beneath me, and the light breeze flowing through the trees and into my face felt like the gentle caress of a mother I never knew. As the sun was setting over the horizon and the darkness grew more prominent, I knew it was time.

"Let's do this."

It was time to go so…. I jumped. As the wind intensified around me and the ground grew closer, I had the strange feeling of time slowing down and decided to recall my life up until this point.

My name is Magus E. Mor. I only know this because the orphanage I was left at had this name inscribed on the basket I was inside; my middle initial was always something I wondered about.

I didn't exactly have a lousy childhood considering my seclusive personality. I enjoyed learning new things, and for the first few years of my life. If my face was not in a book, then I was helping out the matrons of my orphanage.

They weren't forcing me or anything, and they were kind, but I learned that if you practice something enough, you can become good at it, and I wanted to learn as much as I could. My curiosity was insatiable, and I quickly became known by those around me as something of a small genius.

Around 10 years old, I attracted the jealousy of a few other kids, and when they tried to attack me and we had a basic child-level street fight, I discovered a new love in the act of fighting. When the adrenaline was pumping, and death was a possibility, it felt like my blood would boil. By the time I came back to my senses, I was the only one still standing, but it was not that bad, we were kids.

I wanted to learn more, but to do that I needed time and money. I spent a year studying specifically on how I could make money without needing to be seen (thank you internet for unlimited free information), and eventually made some online accounts under fake names and started investing.

It took me another year to turn the $100 I 'collected' from various people on the street into a few thousand, and while I might be intelligent for my age, I'm sure someone was watching out for me because it felt like everything I invested in ended up working out.

So I decided to test out of middle school, and at the age of 12, I earned myself some time, and while I left most of my money to continue investing, I started going to different martial art schools. And let me tell you most of my teachers were astonished at how quickly I absorbed everything.

A few years down the line, I got myself more time by testing out of high school and got permission from the orphanage to live in an apartment on my own as long as my guardian (the head matron) checks in on me every now and then.

Not a big deal considering all my time is dedicated to learning and training with a side of some casual reading of light novels, fanfiction, and watching anime.

I learned about languages, cooking, programming, survival skills, psychology, a whole bunch of stuff. On the physical side, I kept training in every martial art I could find as well as weapon training. I wasn't much into guns, but anything with a blade was extremely comfortable to me.

The only exception to this was a few handguns that I fell in love with after being inspired by anime I watched.

Anyway, this continued until I reached legal adulthood at 18, and using the significant funds I built up from investing and a few apps I made, I decided to travel and see the world.

I spent the next few years exploring the world, learning life lessons, improving my linguistic skills in their own zones, and making real friends.

I learned meditation and spiritual teachings from monks who spent their lives in the mountains. I learned everything I could and enjoyed the ride, as I got older, I began to mellow out and accept what comes at me.

It was when I hit 25 that things took a strange turn.

You see, I always felt comfortable in the shadows. Weird I know, but whenever I was in the shadow of things I felt invigorated, It was strangely comforting. I wasn't emo or anything, and I enjoyed the rest of the world, but when I was in the shadows, I felt truly alive.

Through my physical training, I developed my own style of being in tune with my shadow and lowering my presence in any given place. It worked great for pranks and sneaking around or for disappearing if I was attracting the wrong kind of attention.

When I meditated in the shadows, it felt like I would sink into the warm embrace of the world, and I felt truly free.

It wasn't anything really supernatural just pure training and talent until I hit 25 and my shadow decided to start messing with me, a timer appeared in my shadow and apparently I was the only one who could see it. It showed as '364d 22h 25m 12s' followed by the words 'Forgive me son.'

As I began to ponder about what it could mean, the pain hit. It wasn't instantaneous, but it was gradual. Starting with numb pins and needles feeling and slowly raking up in the center of my body.

Thankfully, after all my years of training and self-discipline, It wasn't that bad, but I decided to go get checked out at a hospital. They did some scans and discovered the beginning of a heart disease.

They told me the healing process will require me to be hospitalized and could take a few years, but a quick look at my timer and I realized that whatever this was when that timer hit the end, it was my time.

Now, most people might freak out and break down, and sure it freaked me out for a bit, but after calming down and thinking logically, I realized I had a great life without any regrets.

So, I told the doctors that I would go to another country for treatment when in reality, I decided to continue my travels, the pain gradually increased, and I knew whatever it was wasn't really my heart. Thankfully like all things I learned in my life, my pain tolerance steadily increased, and I managed to continue at my own pace.

Interestingly enough, the more I accepted my situation and enjoyed the moment, the freer I felt in body and spirit. I still got a rush as an adrenaline junky, but I took whatever came at me.

In my final week, I donated everything I accumulated to the orphanage I grew up in and the few teachers and friends I felt closest to, which was a small fortune and decided how I wanted to go out. Ever ask yourself how you would want to go if you could choose?

Well, I decided to fly. I set up a thick line of rope between two giant stone outcroppings in the mountains in a European country because somehow it was legal there, hooked up a bungee cord to the center of the rope, and waited until nightfall.

The plan was to jump, and when I bounce back and reach my highest point ill cut the line and soar through the sky before well…plummeting into the ground and becoming fertilizer, but hey, it sounded cool in my head.

SO back to the present, the sun had just set, allowing me to see one of the most beautiful scenes on the planet, and the pain had begun to numb my body. Looking at my shadow, I saw the countdown hit the last few minutes, and the message changed from 'Forgive me son' to 'Do not fear, I'm waiting for you.'

Crazy as it may seem, I actually felt comforted by those words and let my body relax, and the shadows of the night fueled me. It almost felt like I was being cheered on by a collection of voices. I knew it was time.

"Let's do this."

I threw on some headphones, played what I felt was appropriate for the moment being the Skyrim intro soundtrack because damn is that an excellent way to get the blood pumping, and jumped.

The pain that became normal for me for the last year vanished with the shadows seeming to fill me as I passed them, and with the wind howling around me, the cord grew taught, and I got launched into the sky.

I drew out my two favorite black knives I personally created when I learned about forging blades and cut the line.

As I flew through the night sky and eventually began my descent I could swear the shadows opened up and welcomed me into its embrace, it wasn't the ground I hit but the shadows that swallowed me almost as if it were a mother welcoming its child home for the first time.

The shadows had welcomed back its son.
