Speaking of Nagas: with this functionality, they can be added as a ninth town, rather than as a replacement for Elves or someone else. There are some nuances, but it is quite possible, although it will take a considerable amount of time to combine the existing Naga mod with this.
Posts from Conflux – 9th town for Heroes 5.
Frankly, I think that the magic of the Spirit faction is criminally underdeveloped in the lore of Ashan. It creates the impression that before the appearance of the undead and constructs, magic was not very powerful, which doesn't align with the history of the Orcs, because there had to be some forces to enslave them and drive them out of the country after the rebellion.
And titans are, in a way, an alternative to simurghs from the Material faction.

One could say that they tried to do this in the seventh installment, as a good portion of their strength – kabiri, jinn, simurghs – are essentially materialized spirits summoned by mages.
Well, titans are more like an alternative to simurghs from the House of the Material.
however, it doesn't feel like a home for the Spirit faction; I believe that T1-T3 create the base for the faction, and there's a spirit-blacksmith and 2 robots.
And thanks to the variability of T7, even though it's a controversial decision, it can be said that the player has a chance to influence the development of their city towards the Spirit or Construct house.
I still dream of a mod based on NCF, where they create three sub-factions for each of the Academy's houses. But even here, the question is: if something can be devised for the Anima and Chimera houses, it's unclear what to do with the Material house...

The idea behind the mod, not the work of Andrey. We need to focus on the Nagas. They are a lore-based faction in Ashan, but we will make them imbalanced elementals "because that's how they were in Heroes 3." Unfortunately, I don't have the skills to implement factions in the fifth game. I'm a complete novice in that area. I'm just a lore expert, texture artist, and inspirer for creating mods, sometimes even a sponsor.
In my ideal world, which I hope will come true, Ubisoft will release Heroes 8, featuring 10 factions: 8 from the fifth game, the Nagas, and the Void Necropolis, which they wanted to implement but couldn't in the seventh game.
Honestly, it's not that great. An unnecessary game faction in Ashan.

But I support any attempts to create something based on our favorite game. Even if something goes wrong, there is always a chance that some element will turn out to be cool and will be useful to other modders.
Definitely a like!

Well, it's easy to test: if the desert and the wastelands have different battle arenas and unit viewing areas, then these are different territories.
IchGViji asked me to fix the death of the light elemental and create an effect, and on my own, I fixed the glow in the hands — I shifted the start time to remove the fading during animation changes
