Star Guardian RPG "Burning Bright": Lux can walk around and fly! Discussion inside

Before you say anything, I'm still learning Unreal Engine 4 and I google every feature that I add so that I can master it before moving on. I'm still a learner but I want to develop something of quality and worthy of a video game developer. I will continue to work on this project especially if I get assistance and then will release the final game for you guys to enjoy (for free of course).

Here is a video of my progress so far: https://youtu.be/NybMzPC0bIo

There are no enemies, no NPCs, and no objectives yet, but it's a start for someone who is just starting out in game developing.

The terrain is some generic desert I downloaded and I added medieval houses models I found online in it. Think of it as a village in Shurima for now. Maybe I will add enemy AI roaming in it that you can fight. (Azir Soldiers, Xer'Sai which are miniature light versions of Rek'Sai, etc?)

I'll need some new more fitting assets to add, such as a high school, Valoran Park from League of Legends, a basic city. Maybe some green plains with caverns and dungeons? I'm heavily going to be inspired by Dragon Quest VIII for the environment and combat.

For the setting:

Not sure when and where the universe of League is set, but I was initially thinking that Luxanna Crownguard would start out at a high school in Demacia then will be given her powers (before she became the Lady of Luminosity) and as the story progresses, the original Star Guardians join that school as "students". The Yordles and Janna are magical beings who join the school to be on guard with Lux, but I'm not sure how to insert Jinx in the story since she is from Zaun. Of course this is set before League of Legends, so before Jinx became a psycho and is studying normally, but it shows that she is a little crazy which shows from her desk covered with paint in Burning Bright.

Maybe Ekko will make an appearance as a student (although I originally imagined him without the mohawk while he was in high school) and he will have a crush on Jinx. Ezreal from Piltover, Ahri from Ionia, Vladimir and Darius probably will be shoehorned in because of their Academy skins. If I can, maybe even Professor Ryze and Headmistress Fiora.

For the plot:

Lux will be your typical student who walks around in the school and does a few things before the RPG starts and she is given her powers to defend Valoran from the Void. She will eventually meet the other Star Guardians and they will go into Lux's school and daily life. Overlord Malzahar is the true big bad and you will often find his Voidlings as powerful enemies. Eventually Malzahar will summon subordinates from the Void, Cho'Gath, Kha'Zix, Rek'Sai, Vel'Koz and Kog'Maw depending on the area of the game you're in. The final boss will be Baron Nashor. But there will be a twist, Jinx will be separated from Lux because of a disagreement (like in Burning Bright's trailer) and you will have to fight the first phase of the final boss without Jinx's help, then she will join in and all the star guardians will combine their powers so that Lux can fire her first ultimate attack.

You eventually fight the True Final Boss Malzahar but that's another story.

I won't reveal who will give Lux her powers, but the second Star Guardians won't get their powers until maybe a sequel where all the Star Guardians fight their final fight with the Dark Star/GreenVoid/Star fiends monsters in Valoran Park with the final boss being the improved Rift Herald. I'm thinking of including Aurelion Sol in the story since he is a cosmic god dragon who will probably assist the Star Guardians. I'm thinking of adding Dark Star characters as bonus bosses which will be huge and require flight combat (unlike standard RPG on ground combat).

For the gameplay:

It will play just like Dragon Quest VIII where you walk around and eventually encounter some enemies to fight every few steps. The only problem I have is that Lux can fly and thus avoid ground encounters. But I'll probably disable flight for some zones to make you obligated to fight monsters. You will be able to see the monsters in the World map before fighting them so you can avoid the random encounters.

Or I can just drop everything and just make Star Guardian Lux 64 where you fly through the rings with terrible controls. Just kidding.

I would like to discuss and see your ideas about this project. I really need some ideas.
