That's true)) but there's one caveat))) - the Factions mysteriously transformed from part to part, so in Heroes 3, the centaurs are essentially in the Forest Union, then magically turn into orcs,... in some part, Inferno disappears, in the 6th, I think, representatives of "Japanese" mythology suddenly appear "from this small world" - Kirins, etc...... The Hydras get tired of "living in the Swamp" and move to the Dark Elves...))))
The disappearance and appearance of Factions is usually justified by the region in which the events take place, for example, the Nagas from the Hashima Islands appeared in the sixth game, where they lived near the Orcs of the Pao Islands, but with Inferno, everything is not so good - they appear only during an eclipse, all the other Factions usually beat them up and live peacefully until the next eclipse.
In any case, the lore already exists, and the regions are divided:
Gnomes live in the north, humans in the center, Orcs in the east, Elves in the west + Nagas - they live on the islands, and there is also a Buddhist version of the Nagas in the glaciers of the Misty Mountains, and there are desert Nagas that look like Arabs.
By the way, about the deserts - besides the Magi, Orcs and Crusaders live there (not a joke, Crusaders chase Orcs all over the world), and there is also Eris - the Undead live there.
In general, a strict block on new Factions appeared in the sixth game, now there are only 6 mortal races (not counting subspecies) + beastmen and Orcs created by the Magi, as well as world evil - Inferno.
There are RPG regions - there are city-states, Elven communities, and pirate fortresses, etc. There are also 2 Gnomish cities outside of Grimheim and ancient ruins filled with the Undead.

Here is a map of Ashan from the seventh game, it is interesting that the cities of the southern Orcs are not marked, apparently they are nomadic in pursuit of sand sharks, but they live in the Sahar desert, that's for sure
