There are human towns and cities, between kingdoms and capitals (of course), the world has different biomes each with different fauna of the place such as magical creatures

Now yes, getting into the intelligent races that exist.

humans, homo sapiens or whatever you call them: the main race that despite not being strong or magical like the other races, are the ones that have the greatest dominance in the biomes, being the race that is most numerous, the human race maintained some alliances with the other races, some humans can be special and be endowed with the gift of magic (1 in 10 thousand people), there are wizards and those who create potions, but the cheap way for those who do not have magic is black magic.

Elves: Elves are a magical race due to their connection with nature and Mother Earth. They are hidden in a specific biome and their population is medium-sized. They are thin and white, with blond hair, mostly green or blue eyes, and pointed ears.

Orcs: Humanoid beings with green skin and pointed ears, red eyes in total and they can measure more than 2m minimum, these are strong but have more muscle than brain most of the time when it comes to reasoning, they are a warrior race for the most part and no one faces them, although some intelligent ones have achieved diplomatic ties. Although they also have exceptions of intelligent orc villages.

Demons: They have red skin and horns on their heads. They are the same as humans, but unlike them, demons have claws and sharp eyes like those of a feline. They do not always seek destruction and they even establish ties.

Dwarves: These are stocky, they are the same as humans but they are Dwarves about the height of a child, but that does not discredit the fact that they are strong, these are such a good race and friends of humans that they go around selling their merchandise here or there or somewhere.

Dark elves: They are the same as elves but with dark or tanned skin, attractive in appearance, except for their fragility, blonde or black hair, green or blue and brown eyes.

I don't know how the hell people manage to write more than 1000 characters, I swear I'm trying hard to make sure this doesn't end up empty.
Because it does not matter if a text is written against my ideals, I have to do it so that the text does not remain that way in my way of seeing.

update, I think I'm getting there by being with more than 1800+ characters the configuration
...
It was achieved my people

We will say how the relationship between the races is (to make it easier)

The relationship between the human race and the elves is somewhat tense but not complicated.

The human race and the dwarves get along like a glove (they are like humans but dwarves) that doesn't affect them, they get along great.

The human race towards demons is between fear and repulsion, although sometimes there is not always repulsion when it comes to dealings.

the human race with the orcs, these are enemies because the orcs are stubborn and do not understand what they teach them, although they are not on bad terms either.

The human race is more stable with dark elves than with elves, being able to coexist normally and seeing them as companions.

the elven race, their relationship with humans is tense although they maintain a diplomatic bond, but seeing humans as evil beings.
the race of elves to the orcs, the orcs drive the elves crazy because they are hard-headed and not as intelligent as they are, including that the elves hate the orcs for their way of being since the elves are beings of peace.

The elf race is different with dwarves, although they are the same as humans but shorter, the elves are not bothered but sometimes they dislike the hygiene of the dwarves.

Elves with demons: Hate, total hate because demons are destruction and pain, the opposite of what elves are, although sometimes deals have been made between leaders among them.
Elves and dark elves are mortal enemies, they hate each other (white vs black).

Continuation of relations between Races.

Dwarves with elves: Elves see elves as very perfectionists and all pretty, but even so elves believe themselves superior for being cleaner, the relationship between them is somewhat tense.

The relationship between dwarves and orcs: A normal relationship, neither good nor bad, although the orcs' stubborn attitude makes their relationship a bit bad.

The relationship between dwarves and demons: Tense since demons are evil with humans as well as with all races, so their relationship is tense.

the Dwarf race with the dark elves: a curious relationship but one could not say so much, something similar to that of the elves.
