Omni Dimensional Incarnation System (Tower of God)

So is this death? This feeling of nothingness and darkness. At least it's not painful anymore.

You see I presumably most likely died just a few moments ago by suffering from multiple sclerosis. And boy is that one painful way to go. Even looking around was really painful at the end.

The only thing I regret is the painful look on the faces of...

Wait? Who am I again? I am starting to forget things like my name and my family. No no, this can't be happening.

While I was having another mental breakdown over gradually losing my memories, a grey colored light entered inside the place I was standing. I think I saw a glimpse of snake there but it also be my imagination.

[Host's soul is stabilized]

[Integration of system is starting]

[1% complete]

Oh this is going in an interesting direction. Somehow my mind is not panicking anymore, even if I don't know about most of the emotional part of my past. After all, what I don't know about can't hurt me in this case.

As soon as that light entered me, it somehow energized my mind. And my thinking went in rational direction.

Hmm let's wait for this to complete and see where this goes.

***

[100% complete]

Ah finally! It felt like forever for it to complete. Honestly, this reminded me of my gaming days when I used to wait for my games to download and then play them.

My favorite genre in gaming is probably the fantasy genre, since it has the best storylines in games in my opinion.

Anyway let's see where this system leads us to. It's probably a reincarnation system or something, though I have no idea why this is here.

[Host welcome to the Omnidimensional Incarnation System!]

This message came in front of my non-existent eyes. The name sounds interesting. What is it about? And why do I have this system thing?

[Host has been selected by the system to be its user because host's soul did not enter any cycle of reincarnation. System needed a stray soul, but all the stray souls so far dissipated before system found them. So you are the first successful host and hopefully the last.]

This texts appears in front of me.

Oh okay but what's the point of all this? I am dead already so what is the objective of this system?

[System's goal is pretty straightforward. It is to bind with a host and make that host a Conceptual Ruler who rules over countless dimensions.]

Okay, good luck with that because I ain't ruling over nobody. It's a troublesome thing.

Organizing a group project as a group leader in school was bad enough, now you want me to rule countless dimensions?! NO THANKS!

[Host doesn't need to become agitated. The type of ruling that system is mentioning is different from the type of ruling that Host is thinking about. By ruling the system means that the host will complete control over the laws of those dimensions. Most of the work will be done by the system so the host doesn't need to worry much.]

Oh well okay. So what's your current function? Also can you communicate with audio too or can you only communicate visually?

[Neither. Well the system can communicate in that manner, but currently it's directly sending information in host's soul and it's conveniently displaying the message as host can see. As for System's functions, there are many but the most relevant are.....]

In short, all the different fictional worlds and dream worlds are real. Since there are infinite dimensions that keep on increasing with something like time. There are also infinite systems and Conceptual Rulers. They are present to make sure that nothing goes wrong with them dimensions.

Anyway, the system allows me to incarnate into an already existing being in any dimension of my choosing, except my first. The first dimension will come from my deep desires, and that apparently is the Fate side of the Nasuverse. That makes me wonder if I am suicidal or something. Well I suppose at least it's not Tsukihime side. Gaia is not a very human friendly Counter Force after all.

Also the character choice in which I will incarnate in will affect how much support I will get from the system. If I choose an extremely weak character, I will get that much more support and easier main mission. If I choose an extremely overpowered character, I will have a debt with the system and also a harder main mission for the dimension. I can also manage the details of the time I will incarnate into the said being. This is all to make it more balanced and also a trial every System bearer must complete to be worthy of being a Conceptual Ruler. According to the System, anyone with a bit of intelligence can complete them with the System support.

About the main mission, once I complete my main mission for this first dimension. I will become the Conceptual Ruler of at least this side of Nasuverse. After that, I will be a completely immortal existence since the system will change my state of being with the help of Root (that's just my guess) probably. I will be able to completely control the dimension through my main body by then.

After completing the main mission, I will be able to incarnate in other dimensions as well. But there is a catch here, I can't use powers that are incompatible with the dimensions, since that will destabilize them. And since I and the system are supposed to look after them, we can't just destroy them ourselves because of our stupidity.

Alright enough explanations. Let's choose the first Incarnation.
