The most pressing issue I see now is in chapter 1 (which is as far as I've read yet). You use that chapter to outline a whole lot about the game - which makes sense, since it's a big part of the story - but almost nothing about the main character, Cian. I really know only a few things: he's a gamer, he's in debt, has a dead-end job and no prospects. Basically, he's every recent college grad I've ever met. But I know nothing about his personality, interests, etc. - the things that make him special. I don't know his
character, and that severely limits my ability to connect with him. I believe characters are the real substance of a story - no matter how cool your world is, or how exciting the plot, if the characters are flat or static the story won't work, because it's characters we care about.
You probably have a lot of Cian's character details planned out already, and maybe they appear in later installments. But I think they should appear now. In fact, I'd argue that chapter 1 shouldn't start with Cian getting his TIVI unit at all - it should start earlier, before he's won the scholarship, with some scenes of his routine and daily life, and some hints at his personality. Gradually show us him and his world in the first chapter.
On a somewhat related note, the info-dump about Worlds and Empires in chapter 1 often reads more like a manual for the game than a novel! I think you might consider not going into quite so much detail about the game just yet - again, give it to us gradually, over the first third of the novel.
There's a sort-of writer's golden rule, which you may have heard: "show, don't tell." Ideally everything that is written should be
part of a scene, even if it's mostly in the character's thoughts. There shouldn't be disembodied narrators explaining stuff - if you have to explain something in detail, make the explanation part of the action or the dialog. So perhaps weave what information you do give us about W&E into Cian's actions: show us Cian daydreaming about the game as he's mopping floors, or have him reading about it online, or talking about it with people, or planning his character, etc. These would be good ways to feed the reader some exposition, while still keeping us within the narrative flow. And it would make Cian getting the scholarship more exciting for us, since we've seen - that is, we've been
shown - how much it means to him, instead of just being
told that.
Now, all of that would take a far bit of rewriting, and maybe that's something you don't want to do at this stage. But I think it would really strengthen the first chapter if
1) we have a stronger sense of who the main character is, and
2) we aren't overwhelmed with info about the game, which we may not need to know for several chapters yet.

For the prologue: I'm not sure how to describe the problem I see here. But take a look at this first paragraph:
Three unusual, humanoid figures stood around a large table in front of a seated man in chains. One, a woman, was tall and lithe, with bright white skin, shimmering silver hair, and eyes so blue they almost glowed. The second, a man with dark brown skin and jet black hair and eyes, was short and stocky – his facial features rough and caveman-like, with a protruding brow and wide chin. The third was androgynous in appearance and stood at a height between the others, with blonde hair, brown eyes, and pale skin with a faint greenish tinge. All three of those standing wore a form fitting, jet black dress uniform with a multi pointed half star insignia on the lapels that seemed to represent a rising sun.
Lots of description, but no action; and the descriptions of each character come one after another, in an orderly sequence, and hit the same notes: build, hair, skin, eyes, dress. It doesn't really grab my attention - in fact, it almost rebuffs me with how much detail there is to take in, all at once, and I can't know how much of it is really significant.
If I were to write this prologue - and I offer this only as an example, certainly not a perscription! - I'd start off something like this:
The room was dark where the man sat, stripped to his boxers. His hands were chained to the chair...
That focuses instantly on the most interesting part of the scene: the naked chained dude. Who is he? Why is he naked? Why is he chained? It's mysterious, and more than a little perilous, and that grabs our attention.
Then I'd move on to the unusual figures around him, and rather than describing them all at once I'd do so when each speaks:
“It’s no use. None of them can understand us,” spoke the shortest one, a man with dark skin and jet-black hair, his face rough and troglodyte, with its protruding brow and wide chin.
The second figure, a tall woman with bright white skin, replied "But we’re speaking his language Kodai! He should be able to understand!” Unconsciously she flipped a lock of shimmering silver hair away from her eyes, so blue they almost glowed. (...)
And so on. Again it just keeps everything from piling onto us all at once.
The rest of the prologue is good, it's just that very first part that's hard to process. But that's the most important part!
