What if we tried to create a movie script together!

No problem, I can offer some advice, right?

1)

Once upon a time, in distant, or perhaps not so distant, times (a rather cliché beginning, isn't it?), when the lands were not filled with skyscrapers and garages, nor with brothels and nightclubs (with all sorts of ecstasy), but with magnificent eastern palaces of mages, impregnable bastions of humans, majestic and formidable fortresses of dwarves, mysterious and alluring dungeons of dark elves, when almost everywhere there were giant trees of elves, and when simply walking through the forest, one could easily stumble upon some undead or demon. It is about these times that our story will be told...

The beginning suggests that these events took place on Earth, but that is not the case. There should be no brothels, skyscrapers, or anything else that would suggest that the action takes place on Earth... Try starting with a description of someone (the second paragraph)... And in general, to make it easier, try sketching out a description of a dark elf city. The hero himself... Other cities and races. In general, whoever is working on the description of this race should try. You also need to roughly imagine the world – where are the mountains, what is the river system, how vast are the deserts or steppes, what are the forests... Create a world, taking into account the races, so that each one finds something pleasing to its heart... And the beginning can be added later. And connect the pieces of text, adding some elements that connect them...

2) You write at the beginning – (these are not quotes) "dwarven fortresses," "dark elf dungeons"... "let's move to the dark elf fortress..."
You need to decide on the names. For example, the names – city, village, settlement, citadel, underground settlement, underground city... perhaps even fortress (or is this the name for dwarven settlements) – will be common. There are possibilities...

About the names of cities...
I don't know what they were called in Heroes 1, 2, and 4, but even in 3 and 5 they were different... You need to decide what they will be called:
Humans – Castle
Wood Elves – ?
Orcs – Stronghold
Dwarves – Fortress?
Undead – Necropolis
Demons – Inferno
Dark Elves – Dungeon?

I don't remember about the elves. Maybe something else...

3) The phrase "impregnable bastions"...

This can be easily fixed by adding "seemingly."
Seemingly impregnable bastions...

Or "almost inaccessible," or "seemingly almost inaccessible..."

In short, we can think about this later...

4) Naturally, the main conflict is between Order and Chaos, i.e., humans, dwarves, elves (wood and dark), orcs against Inferno (Chaos).
That is, 4 races out of 6 against one? And another one is on its own? That's a big imbalance... why can't the orcs also be on their own? And help whoever they want (who pays more, who is stronger, etc.)...

5) Just off the top of my head, based on that little piece-beginning:

The first sentence is too long and cluttered. It needs to be broken up. The last line, about meeting a demon and an undead in the forest, can easily be made into a separate sentence...

Spststya – спустя (meaning "later")

6)

I was thinking and I want to say that we would not mind having an artist on our team who would illustrate some of the chapters with beautiful drawings, so if everyone agrees with me, we will look for an illustrator!

We can put this on hold for now. First, we just need to write, confirm that everything is written correctly, that nothing is confused, and that it suits all of you... At least write a few finished chapters...

P.S.: "dark elf dungeon" sounds like a tautology. Maybe these elves will have a "Dungeon"?

I wrote this post for a long time, and you already replied to the previous one:)
